+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.

+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.

+
+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.

+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.

+This patch is good enough for Krait, but soon I'll need to
+support a "safe rate" where we ask a clock what rate it needs to be running
+at to be sure it's within voltage constraints. Right now safe parent
+handles that problem on Krait, but on other platforms it won't work.

+On some devices (MSM8974 for example), the HFPLLs are
+instantiated within the Krait processor subsystem as separate
+register regions. Add a driver for these PLLs so that we can
+provide HFPLL clocks for use by the system.

+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.

+purposes probe these devices and expose a mux clock that chooses
+between PXO and PLL8.

+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.

+Date: Fri, 30 May 2014 16:36:11 -0700
+Subject: [PATCH] FROMLIST: cpufreq: Add a cpufreq-krait based on cpufreq-cpu0
+
+Krait processors have individual clocks for each CPU that can
+scale independently from one another. cpufreq-cpu0 is fairly
+close to this, but assumes that there is only one clock for all
+CPUs. Add a driver to support the Krait configuration.
+
+TODO: Merge into cpufreq-cpu0? Or make generic?

+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: [PATCH 1/8] stmmac: add phy-handle support to the platform layer
+
+On stmmac driver, PHY specification in device-tree was done using the
+non-standard property "snps,phy-addr". Specifying a PHY on a different
+MDIO bus that the one within the stmmac controller doesn't seem to be
+possible when device-tree is used.
+
+This change adds support for the phy-handle property, as specified in
+Documentation/devicetree/bindings/net/ethernet.txt.

+We will want to do additional clean-up on certain errors. Therefore,

+This patch doesn't change anything functionally.

+Subject: [PATCH 3/8] stmmac: add fixed-link device-tree support
+
+In case DT is used, this change adds the ability to the stmmac driver to
+detect a fixed-link PHY, instanciate it, and use it during
+phy_connect().
+
+Fixed link PHYs DT usage is described in:
+Documentation/devicetree/bindings/net/fixed-link.txt

+
+The ethernet controller available in IPQ806x is a Synopsys DesignWare
+Gigabit MAC IP core, already supported by the stmmac driver.
+
+This glue layer implements some platform specific settings required to
+get the controller working on an IPQ806x based platform.

++* IPQ806x DWMAC Ethernet controller
++
++The device inherits all the properties of the dwmac/stmmac devices
++described in the file net/stmmac.txt with the following changes.
++
++Required properties:
++
++- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
++ and any applicable more detailed version number
++ described in net/stmmac.txt
++
++- qcom,nss-common: should contain a phandle to a syscon device mapping the
++ nss-common registers.
++
++- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
++ qsgmii-csr registers.
++
++Example:
++
++ gmac: ethernet@37000000 {
++ device_type = "network";
++ compatible = "qcom,ipq806x-gmac";
++ reg = <0x37000000 0x200000>;
++ interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
++ interrupt-names = "macirq";
++
++ qcom,nss-common = <&nss_common>;
++ qcom,qsgmii-csr = <&qsgmii_csr>;
++
++ clocks = <&gcc GMAC_CORE1_CLK>;
++ clock-names = "stmmaceth";
++
++ resets = <&gcc GMAC_CORE1_RESET>;
++ reset-names = "stmmaceth";
++ };
