-Subject: clk: qcom: common: Add API to register board clocks backwards
- compatibly
-
-We want to put the XO board clocks into the dt files, but we also
-need to be backwards compatible with an older dtb. Add an API to
-the common code to do this. This also makes a place for us to
-handle the case when the RPM clock driver is enabled and we don't
-want to register the fixed factor clock.

-Subject: clk: qcom: Move cxo/pxo/xo into dt files
-
-Put these clocks into the dt files instead of registering them
-from C code. This provides a few benefits. It allows us to
-specify the frequency of these clocks at the board level instead
-of hard-coding them in the driver. It allows us to insert an RPM
-clock in between the consumers of the crystals and the actual
-clock. And finally, it helps us transition the GCC driver to use
-RPM clocks when that configuration is enabled.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The MSM8660, APQ8060, IPQ806x and MSM8960 have a GCC clock
-to the message RAM used by the RPM. This needs to be enabled
-for messages to pass through. This is a crude solution that
-simply prepare/enable at probe() and disable/unprepare
-at remove(). More elaborate PM is probably possible to
-add later.
-
-The construction uses IS_ERR() to gracefully handle the
-platforms that do not provide a message RAM clock. It will
-bail out of probe only if the clock is hitting a probe
-deferral situation.
-
-Of course this requires the proper device tree set-up:
-
-rpm: rpm@104000 {
- compatible = "qcom,rpm-msm8660";
- clocks = <&gcc RPM_MSG_RAM_H_CLK>;
- clock-names = "ram";
- ...
-};
-
-I have provided this in the MSM8660 device tree, and will
-provide patches for the other targets.

-Subject: watchdog: core: add restart handler support
-
-Many watchdog drivers implement the same code to register a restart
-handler. This patch provides a generic way to set such a function.
-
-The patch adds a new restart watchdog operation. If a restart priority
-greater than 0 is needed, the driver can call
-watchdog_set_restart_priority to set it.

-Subject: watchdog: core: add reboot notifier support
-
-Many watchdog drivers register a reboot notifier in order to stop the
-watchdog on system reboot. Thus we can factorize this code in the
-watchdog core.
-
-For that purpose, a new notifier block is added in watchdog_device for
-internal use only, as well as a new watchdog_stop_on_reboot helper
-function.
-
-If this helper is called, watchdog core registers the related notifier
-block and will stop the watchdog when SYS_HALT or SYS_DOWN is received.
-
-Since this operation can be critical on some platforms, abort the device
-registration if the reboot notifier registration fails.

-Subject: watchdog: Use static struct class watchdog_class in stead of pointer
-
-We need few sysfs attributes to know different status of a watchdog device.
-To do that, we need to associate .dev_groups with watchdog_class. So
-convert it from pointer to static.
-Putting this static struct in watchdog_dev.c, so that static device
-attributes defined in that file can be attached to it.

-Subject: watchdog: Read device status through sysfs attributes
-
-This patch adds following attributes to watchdog device's sysfs interface
-to read its different status.
-
-* state - reads whether device is active or not
-* identity - reads Watchdog device's identity string.
-* timeout - reads current timeout.
-* timeleft - reads timeleft before watchdog generates a reset
-* bootstatus - reads status of the watchdog device at boot
-* status - reads watchdog device's internal status bits
-* nowayout - reads whether nowayout feature was set or not
-
-Testing with iTCO_wdt:
- # cd /sys/class/watchdog/watchdog1/
- # ls
-bootstatus dev device identity nowayout power state
-subsystem timeleft timeout uevent
- # cat identity
-iTCO_wdt
- # cat timeout
-30
- # cat state
-inactive
- # echo > /dev/watchdog1
- # cat timeleft
-26
- # cat state
-active
- # cat bootstatus
-0
- # cat nowayout
-0

-Subject: watchdog: Create watchdog device in watchdog_dev.c
-
-The watchdog character device is currently created in watchdog_dev.c,
-and the watchdog device in watchdog_core.c. This results in
-cross-dependencies, since device creation needs to know the watchdog
-character device number as well as the watchdog class, both of which
-reside in watchdog_dev.c.
-
-Create the watchdog device in watchdog_dev.c to simplify the code.
-
-Inspired by earlier patch set from Damien Riegel.

-From b4ffb1909843b28f3b1b60197d517b123b7a9b66 Mon Sep 17 00:00:00 2001
-From: Guenter Roeck <linux@roeck-us.net>
-Date: Fri, 25 Dec 2015 16:01:42 -0800
-Subject: watchdog: Separate and maintain variables based on variable lifetime
-
-All variables required by the watchdog core to manage a watchdog are
-currently stored in struct watchdog_device. The lifetime of those
-variables is determined by the watchdog driver. However, the lifetime
-of variables used by the watchdog core differs from the lifetime of
-struct watchdog_device. To remedy this situation, watchdog drivers
-can implement ref and unref callbacks, to be used by the watchdog
-core to lock struct watchdog_device in memory.
-
-While this solves the immediate problem, it depends on watchdog drivers
-to actually implement the ref/unref callbacks. This is error prone,
-often not implemented in the first place, or not implemented correctly.
-
-To solve the problem without requiring driver support, split the variables
-in struct watchdog_device into two data structures - one for variables
-associated with the watchdog driver, one for variables associated with
-the watchdog core. With this approach, the watchdog core can keep track
-of its variable lifetime and no longer depends on ref/unref callbacks
-in the driver. As a side effect, some of the variables originally in
-struct watchdog_driver are now private to the watchdog core and no longer
-visible in watchdog drivers.
-
-As a side effect of the changes made, an ioctl will now always fail
-with -ENODEV after a watchdog device was unregistered with the character
-device still open. Previously, it would only fail with -ENODEV in some
-situations. Also, ioctl operations are now atomic from driver perspective.
-With this change, it is now guaranteed that the driver will not unregister
-a watchdog between a timeout change and the subsequent ping.
-
-The 'ref' and 'unref' callbacks in struct watchdog_driver are no longer
-used and marked as deprecated.

-Subject: watchdog: qcom: add option for standalone watchdog not in timer block
-
-Commit 0dfd582e026a ("watchdog: qcom: use timer devicetree
-binding") moved to use the watchdog as a subset timer
-register block. Some devices have the watchdog completely
-standalone with slightly different register offsets as
-well so let's account for the differences here.
-
-The existing "kpss-standalone" compatible string doesn't
-make it entirely clear exactly what the device is so
-rename to "kpss-wdt" to reflect watchdog timer
-functionality. Also update ipq4019 DTS with an SoC
-specific compatible.

-Subject: watchdog: da9052_wdt: Drop reference counting
-
-Reference counting is now implemented in the watchdog core and no longer
-required in watchdog drivers.
-
-Since it was implememented a no-op, and since the local memory is allocated
-with devm_kzalloc(), the reference counting code in the driver really did
-not really work anyway, and this patch effectively fixes a bug which could
-cause a crash on unloading if the watchdog device was still open.

-This adds initial support for clocks controlled by the Resource
-Power Manager (RPM) processor on some Qualcomm SoCs, which use
-the qcom_smd_rpm driver to communicate with RPM.
-Such platforms are msm8916, apq8084 and msm8974.
-
-The RPM is a dedicated hardware engine for managing the shared
-SoC resources in order to keep the lowest power profile. It
-communicates with other hardware subsystems via shared memory
-and accepts clock requests, aggregates the requests and turns
-the clocks on/off or scales them on demand.
-
-This driver is based on the codeaurora.org driver:

-+Qualcomm RPM Clock Controller Binding
-+------------------------------------------------
-+The RPM is a dedicated hardware engine for managing the shared
-+SoC resources in order to keep the lowest power profile. It
-+communicates with other hardware subsystems via shared memory
-+and accepts clock requests, aggregates the requests and turns
-+the clocks on/off or scales them on demand.
-+
-+Required properties :
-+- compatible : shall contain only one of the following. The generic
-+ compatible "qcom,rpmcc" should be also included.
-+
-+ "qcom,rpmcc-msm8916", "qcom,rpmcc"
-+
-+- #clock-cells : shall contain 1
-+
-+Example:
-+ smd {
-+ compatible = "qcom,smd";
-+
-+ rpm {
-+ interrupts = <0 168 1>;
-+ qcom,ipc = <&apcs 8 0>;
-+ qcom,smd-edge = <15>;
-+
-+ rpm_requests {
-+ compatible = "qcom,rpm-msm8916";
-+ qcom,smd-channels = "rpm_requests";
-+
-+ rpmcc: clock-controller {
-+ compatible = "qcom,rpmcc-msm8916", "qcom,rpmcc";
-+ #clock-cells = <1>;
-+ };

-Subject: clk: qcom: Add support for RPM Clocks
-
-This adds initial support for clocks controlled by the Resource
-Power Manager (RPM) processor on some Qualcomm SoCs, which use
-the qcom_rpm driver to communicate with RPM.
-Such platforms are apq8064 and msm8960.

-Subject: thermal: qcom: tsens: Add a skeletal TSENS drivers
-
-TSENS is Qualcomms' thermal temperature sensor device. It
-supports reading temperatures from multiple thermal sensors
-present on various QCOM SoCs.
-Calibration data is generally read from a non-volatile memory
-(eeprom) device.
-
-Add a skeleton driver with all the necessary abstractions so
-a variety of qcom device families which support TSENS can
-add driver extensions.
-
-Also add the required device tree bindings which can be used
-to describe the TSENS device in DT.

-Date: Thu, 5 May 2016 14:21:40 +0530
-Subject: thermal: qcom: tsens-8916: Add support for 8916 family of SoCs
-
-Add support to calibrate sensors on 8916 family and also add common
-functions to read temperature from sensors (This can be reused on
-other SoCs having similar TSENS device)
-The calibration data is read from eeprom using the generic nvmem
-framework apis.
-
-Based on the original code by Siddartha Mohanadoss and Stephen Boyd.

-Subject: thermal: qcom: tsens-8960: Add support for 8960 family of SoCs
-
-8960 family of SoCs have the TSENS device as part of GCC, hence
-the driver probes the virtual child device created by GCC and
-uses the parent to extract all DT properties and reuses the GCC
-regmap.
-
-Also GCC/TSENS are part of a domain thats not always ON.
-Hence add .suspend and .resume hooks to save and restore some of
-the inited register context.
-
-Also 8960 family have some of the TSENS init sequence thats
-required to be done by the HLOS driver (some later versions of TSENS
-do not export these registers to non-secure world, and hence need
-these initializations to be done by secure bootloaders)
-
-8660 from the same family has just one sensor and hence some register
-offset/layout differences which need special handling in the driver.
-
-Based on the original code from Siddartha Mohanadoss, Stephen Boyd and
-Narendran Rajan.

-Subject: nvmem: core: return error for non word aligned access
-
-nvmem providers have restrictions on register strides, so return error
-when users attempt to read/write buffers with sizes which are less
-than word size.
-
-Without this patch the userspace would continue to try as it does not
-get any error from the nvmem core, resulting in a hang or endless loop

-Subject: nvmem: core: fix error path in nvmem_add_cells()
-
-The current code fails to nvmem_cell_drop(cells[0]) - even worse, if
-the loop above fails already at i==0, we'll enter an essentially
-infinite loop doing nvmem_cell_drop on cells[-1], cells[-2], ... which
-is unlikely to end well.
-
-Also, we're not freeing the temporary backing array cells on the error
-path.

-Subject: nvmem: Add flag to export NVMEM to root only
-
-Legacy AT24, AT25 EEPROMs are exported in sys so that only root can
-read the contents. The EEPROMs may contain sensitive information. Add
-a flag so the provide can indicate that NVMEM should also restrict
-access to root only.

-This adds a 'select' Kconfig statement to ensure it's always

-If the maximum_speed is not set, set it to a known value, either
-SuperSpeed or SuperSpeedPlus based on the type of controller we are
-using. If we are on DWC_usb31 controller, check the PHY interface to see
-if it is capable of SuperSpeedPlus.
-
-Also this check is moved after dwc3_core_init() so that we can check
-dwc->revision.

-Subject: usb: dwc3: core: improve reset sequence
-
-According to Synopsys Databook, we shouldn't be
-relying on GCTL.CORESOFTRESET bit as that's only for
-debugging purposes. Instead, let's use DCTL.CSFTRST
-if we're OTG or PERIPHERAL mode.
-
-Host side block will be reset by XHCI driver if
-necessary. Note that this reduces amount of time
-spent on dwc3_probe() by a long margin.
-
-We're still gonna wait for reset to finish for a
-long time (default to 1ms max), but tests show that
-the reset polling loop executed at most 19 times
-(modprobe dwc3 && modprobe -r dwc3 executed 1000
-times in a row).

-Subject: usb: dwc3: drop FIFO resizing logic
-
-That FIFO resizing logic was added to support OMAP5
-ES1.0 which had a bogus default FIFO size. I can't
-remember the exact size of default FIFO, but it was
-less than one bulk superspeed packet (<1024) which
-would prevent USB3 from ever working on OMAP5 ES1.0.
-
-However, OMAP5 ES1.0 support has been dropped by
-commit aa2f4b16f830 ("ARM: OMAP5: id: Remove ES1.0
-support") which renders FIFO resizing unnecessary.

-Subject: usb: dwc3: remove num_event_buffers
-
-We never, ever route any of the other event buffers
-so we might as well drop support for them.
-
-Until someone has a real, proper benefit for
-multiple event buffers, we will rely on a single
-one. This also helps reduce memory footprint of
-dwc3.ko which won't allocate memory for the extra
-event buffers.

-Subject: [PATCH] usb: dwc3: add generic OF glue layer
-
-For simple platforms which merely enable some clocks
-and populate its children, we can use this generic
-glue layer to avoid boilerplate code duplication.
-
-For now this supports Qcom and Xilinx, but if we
-find a way to add generic handling of regulators and
-optional PHYs, we can absorb exynos as well.

-Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
- enabled
-
-If multiple PCIe devices are present in the system, the kernel will
-panic at boot time when trying to scan the PCI buses. This happens on
-IPQ806x based platforms, which has 3 PCIe ports.
-
-Enabling this option allows the kernel to assign the pci-domains
-according to the device-tree content. This allows multiple PCIe
-controllers to coexist in the system.

-Krait CPUs have a handful of L2 cache controller registers that
-live behind a cp15 based indirection register. First you program
-the indirection register (l2cpselr) to point the L2 'window'
-register (l2cpdr) at what you want to read/write. Then you
-read/write the 'window' register to do what you want. The
-l2cpselr register is not banked per-cpu so we must lock around
-accesses to it to prevent other CPUs from re-pointing l2cpdr
-underneath us.

-Subject: [PATCH 1/2] clk: mux: Split out register accessors for reuse
-
-We want to reuse the logic in clk-mux.c for other clock drivers
-that don't use readl as register accessors. Fortunately, there
-really isn't much to the mux code besides the table indirection
-and quirk flags if you assume any bit shifting and masking has
-been done already. Pull that logic out into reusable functions
-that operate on an optional table and some flags so that other
-drivers can use the same logic.

-Subject: [PATCH 2/2] clk: Avoid sending high rates to downstream clocks during
- set_rate
-
-If a clock is on and we call clk_set_rate() on it we may get into
-a situation where the clock temporarily increases in rate
-dramatically while we walk the tree and call .set_rate() ops. For
-example, consider a case where a PLL feeds into a divider.
-Initially the divider is set to divide by 1 and the PLL is
-running fairly slow (100MHz). The downstream consumer of the
-divider output can only handle rates =< 400 MHz, but the divider
-can only choose between divisors of 1 and 4.
-
- +-----+ +----------------+
- | PLL |-->| div 1 or div 4 |---> consumer device
- +-----+ +----------------+
-
-To achieve a rate of 400MHz on the output of the divider, we
-would have to set the rate of the PLL to 1.6 GHz and then divide
-it by 4. The current code would set the PLL to 1.6GHz first while
-the divider is still set to 1, thus causing the downstream
-consumer of the clock to receive a few clock cycles of 1.6GHz
-clock (far beyond it's maximum acceptable rate). We should be
-changing the divider first before increasing the PLL rate to
-avoid this problem.
-
-Therefore, set the rate of any child clocks that are increasing
-in rate from their current rate so that they can increase their
-dividers if necessary. We assume that there isn't such a thing as
-minimum rate requirements.

-Subject: [PATCH] clk: Add safe switch hook
-
-Sometimes clocks can't accept their parent source turning off
-while the source is reprogrammed to a different rate. Most
-notably CPU clocks require a way to switch away from the current
-PLL they're running on, reprogram that PLL to a new rate, and
-then switch back to the PLL with the new rate once they're done.
-Add a hook that drivers can implement allowing them to return a
-'safe parent' that they can switch their parent to while the
-upstream source is reprogrammed to support this.

-instantiated within the Krait processor subsystem as separate
-register regions. Add a driver for these PLLs so that we can

-The Krait clocks are made up of a series of muxes and a divider
-that choose between a fixed rate clock and dedicated HFPLLs for
-each CPU. Instead of using mmio accesses to remux parents, the
-Krait implementation exposes the remux control via cp15
-registers. Support these clocks.

-The Krait CPU clocks are made up of a primary mux and secondary
-mux for each CPU and the L2, controlled via cp15 accessors. For
-Kraits within KPSSv1 each secondary mux accepts a different aux
-source, but on KPSSv2 each secondary mux accepts the same aux
-source.

-This patch removes the crci information from the dma channel property. At least
-one client device requires using more than one CRCI value for a channel. This
-does not match the current binding and the crci information needs to be removed.
-
-Instead, the client device will provide this information via other means.

-Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
-controller found in the MSM8x60 and IPQ/APQ8064 platforms.
-
-The ADM supports both memory to memory transactions and memory
-to/from peripheral device transactions. The controller also provides flow
-control capabilities for transactions to/from peripheral devices.
-
-The initial release of this driver supports slave transfers to/from peripherals
-and also incorporates CRCI (client rate control interface) flow control.

-Some controllers can access the factory bad block marker from OOB only
-when they read it in raw mode. When ECC is enabled, these controllers
-discard reading/writing bad block markers, preventing access to them
-altogether.
-
-The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
-This results in the nand driver's ecc->read_oob() op to be called, which
-works with ECC enabled.
-
-Create a new BBT option flag that tells nand_bbt to force the mode to
-MTD_OPS_RAW. This would result in the correct op being called for the
-underlying nand controller driver.

-
-The Qualcomm NAND controller is found in SoCs like IPQ806x, MSM7xx,
-MDM9x15 series.
-
-It exists as a sub block inside the IPs EBI2 (External Bus Interface 2)
-and QPIC (Qualcomm Parallel Interface Controller). These IPs provide a
-broader interface for external slow peripheral devices such as LCD and
-NAND/NOR flash memory or SRAM like interfaces.
-
-We add support for the NAND controller found within EBI2. For the SoCs
-of our interest, we only use the NAND controller within EBI2. Therefore,
-it's safe for us to assume that the NAND controller is a standalone block
-within the SoC.
-
-The controller supports 512B, 2kB, 4kB and 8kB page 8-bit and 16-bit NAND
-flash devices. It contains a HW ECC block that supports BCH ECC (4, 8 and
-16 bit correction/step) and RS ECC(4 bit correction/step) that covers main
-and spare data. The controller contains an internal 512 byte page buffer
-to which we read/write via DMA. The EBI2 type NAND controller uses ADM DMA
-for register read/write and data transfers. The controller performs page
-reads and writes at a codeword/step level of 512 bytes. It can support up
-to 2 external chips of different configurations.
-
-The driver prepares register read and write configuration descriptors for
-each codeword, followed by data descriptors to read or write data from the
-controller's internal buffer. It uses a single ADM DMA channel that we get
-via dmaengine API. The controller requires 2 ADM CRCIs for command and
-data flow control. These are passed via DT.
-
-The ecc layout used by the controller is syndrome like, but we can't use
-the standard syndrome ecc ops because of several reasons. First, the amount
-of data bytes covered by ecc isn't same in each step. Second, writing to
-free oob space requires us writing to the entire step in which the oob
-lies. This forces us to create our own ecc ops.
-
-One more difference is how the controller accesses the bad block marker.
-The controller ignores reading the marker when ECC is enabled. ECC needs
-to be explicity disabled to read or write to the bad block marker. For
-this reason, we use the newly created flag NAND_BBT_ACCESS_BBM_RAW to
-read the factory provided bad block markers.
-
-v3:
-- Refactor dma functions for maximum reuse
-- Use dma_slave_confing on stack
-- optimize and clean upempty_page_fixup using memchr_inv
-- ensure portability with dma register reads using le32_* funcs
-- use NAND_USE_BOUNCE_BUFFER instead of doing it ourselves
-- fix handling of return values of dmaengine funcs
-- constify wherever possible
-- Remove dependency on ADM DMA in Kconfig
-- Misc fixes and clean ups
-
-v2:
-- Use new BBT flag that allows us to read BBM in raw mode
-- reduce memcpy-s in the driver
-- some refactor and clean ups because of above changes

-+* Qualcomm NAND controller
-+
-+Required properties:
-+- compatible: should be "qcom,ebi2-nand" for IPQ806x
-+- reg: MMIO address range
-+- clocks: must contain core clock and always on clock
-+- clock-names: must contain "core" for the core clock and "aon" for the
-+ always on clock
-+- dmas: DMA specifier, consisting of a phandle to the ADM DMA
-+ controller node and the channel number to be used for
-+ NAND. Refer to dma.txt and qcom_adm.txt for more details
-+- dma-names: must be "rxtx"
-+- qcom,cmd-crci: must contain the ADM command type CRCI block instance
-+ number specified for the NAND controller on the given
-+ platform
-+- qcom,data-crci: must contain the ADM data type CRCI block instance
-+ number specified for the NAND controller on the given
-+ platform
-+
-+Optional properties:
-+- nand-bus-width: bus width. Must be 8 or 16. If not present, 8 is chosen
-+ as default
-+
-+- nand-ecc-strength: number of bits to correct per ECC step. Must be 4 or 8
-+ bits. If not present, 4 is chosen as default
-+- nand-on-flash-bbt: Create/use on-flash bad block table
-+
-+The device tree may optionally contain sub-nodes describing partitions of the
-+address space. See partition.txt for more detail.
-+
-+Example:
-+
-+nand@1ac00000 {

-Subject: PM / OPP: Support adjusting OPP voltages at runtime
-
-On some SoCs the Adaptive Voltage Scaling (AVS) technique is
-employed to optimize the operating voltage of a device. At a
-given frequency, the hardware monitors dynamic factors and either
-makes a suggestion for how much to adjust a voltage for the
-current frequency, or it automatically adjusts the voltage
-without software intervention. Add an API to the OPP library for
-the former case, so that AVS type devices can update the voltages
-for an OPP when the hardware determines the voltage should
-change. The assumption is that drivers like CPUfreq or devfreq
-will register for the OPP notifiers and adjust the voltage
-according to suggestions that AVS makes.

-Subject: OPP: Allow notifiers to call dev_pm_opp_get_{voltage, freq} RCU-free
-
-We pass the dev_pm_opp structure to OPP notifiers but the users
-of the notifier need to surround calls to dev_pm_opp_get_*() with
-RCU read locks to avoid lockdep warnings. The notifier is already
-called with the dev_opp's srcu lock held, so it should be safe to
-assume the devm_pm_opp structure is already protected inside the
-notifier. Update the lockdep check for this.

-Subject: clk: qcom: Add support for regmap mux-div clocks
-
-Add support for hardware that support switching both parent clocks and the
-divider at the same time. This avoids generating intermediate frequencies
-from either the old parent clock and new divider or new parent clock and
-old divider combinations.

-Currently the RPM/RPM-SMD clock drivers do not register the xo clocks,
-so we should always add factor clock. When we later add xo clocks support
-into the drivers, we should update this function to skip registration.
-By doing so we avoid any DT dependencies.

-Subject: [PATCH] HACK: arch: arm: force ZRELADDR on arch-qcom
-
-ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
-on most ARM architectures. This automatically calculate ZRELADDR by
-masking PHYS_OFFSET with 0xf8000000.
-
-However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
-network accelerators, and the bootloader removes this section from the
-layout passed from the ATAGS (when used).
-
-For newer bootloader, when DT is used, this is not a problem, we just
-reserve this memory in the device tree. But if the bootloader doesn't
-have DT support, then ATAGS have to be used. In this case, the ARM
-decompressor will position the kernel in this low mem, which will not be
-in the RAM section mapped by the bootloader, which means the kernel will
-freeze in the middle of the boot process trying to map the memory.
-
-As a work around, this patch allows disabling AUTO_ZRELADDR when
-ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
-which don't support device-tree, which is the case on certain early
-IPQ806x based designs.

-Subject: soc: qcom: ipq806x: Increase Atomic Coherent Pool size
-
-Linux 3.14, by default allocates a 256K Atomic Coherent Pool.
-However, Linux 3.4 seems to have allocated ~1.8M for the same.
-256K doesn't seem to be enough for the WiFi driver. Hence,
-setting the size to be similar to 3.4.

-This patch contains initial init & registration code for QCA8337. It
-will detect a QCA8337 switch, if present and declared in DT/platform.
-
-Each port will be represented through a standalone net_device interface,
-as for other DSA switches. CPU can communicate with any of the ports by
-setting an IP@ on ethN interface. Ports cannot communicate with each
-other just yet.
-
-Link status will be reported through polling, and we don't use any
-encapsulation.

-+* Qualcomm Atheros AR8xxx switch family
-+
-+Required properties:
-+
-+- compatible: should be "qca,ar8xxx"
-+- dsa,mii-bus: phandle to the MDIO bus controller, see dsa/dsa.txt
-+- dsa,ethernet: phandle to the CPU network interface controller, see dsa/dsa.txt
-+- #size-cells: must be 0
-+- #address-cells: must be 2, see dsa/dsa.txt
-+
-+Subnodes:
-+
-+The integrated switch subnode should be specified according to the binding
-+described in dsa/dsa.txt.
-+
-+Optional properties:
-+
-+- qca,port6-phy-mode: if specified, the driver will configure Port 6 in the
-+ given phy-mode. See Documentation/devicetree/bindings/net/ethernet.txt for
-+ the list of valid phy-mode.
-+
-+- qca,port6-phy-id: if specified, the driver will connect Port 6 to the PHY
-+ given as a parameter. In this case, Port6 and the corresponding PHY will be
-+ isolated from the rest of the switch. From a system perspective, they will
-+ act as a regular PHY.
-+
-+Example:
-+
-+ dsa@0 {
-+ compatible = "qca,ar8xxx";
-+ #address-cells = <2>;
-+ #size-cells = <0>;
-+
-+ dsa,ethernet = <&ethernet0>;
-+ dsa,mii-bus = <&mii_bus0>;
-+
-+ switch@0 {
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+ reg = <0 0>; /* MDIO address 0, switch 0 in tree */
-+
-+ qca,port6-phy-mode = "sgmii";
-+ qca,port6-phy-id = <4>;
-+
-+ port@0 {
-+ reg = <11>;
-+ label = "cpu";

-
-Wait to signal done until we get all of the interrupts we are expecting
-to get for a transaction. If we don't wait for the input done flag, we
-can be inbetween transactions when the done flag comes in and this can
-mess up the next transaction.

-Subject: [PATCH] spi: qup: Fix DMA mode to work correctly
-
-This patch fixes a few issues with the DMA mode. The QUP needs to be
-placed in the run mode before the DMA transactions are executed. The
-conditions for being able to DMA vary between revisions of the QUP.
-This is due to v1.1.1 using ADM DMA and later revisions using BAM.

-Subject: [PATCH] spi: qup: properly detect extra interrupts
-
-It's possible for a SPI transaction to complete and get another
-interrupt and have it processed on the same spi_transfer before the
-transfer_one can set it to NULL.
-
-This masks unexpected interrupts, so let's set the spi_transfer to
-NULL in the interrupt once the transaction is done. So we can
-properly detect these bad interrupts and print warning messages.

-If there is a property "append-rootblock" in DT under /chosen

-Only command line ATAG will be processed, the rest of the ATAGs
