-Subject: [PATCH 02/25] reset: Fix compile when reset RESET_CONTROLLER is not
- selected
-
-Drivers need to protect their reset api calls with #ifdef to avoid compile
-errors.
-
-This patch adds dummy wrappers in the same way that linux/of.h does it.

-Subject: [PATCH 11/25] MIPS: ralink: add support for systick timer found on
- newer ralink SoC
-
-Newer Ralink SoC (MT7620x and RT5350) have a 50KHz clock that runs independent
-of the SoC master clock. If we want to automatic frequency scaling to work we
-need to use the systick timer as the clock source.

-+Ralink SoC RT2880 SPI master controller.
-+
-+This SPI controller is found on most wireless SoCs made by ralink.
-+
-+Required properties:
-+- compatible : "ralink,rt2880-spi"
-+- reg : The register base for the controller.
-+- #address-cells : <1>, as required by generic SPI binding.
-+- #size-cells : <0>, also as required by generic SPI binding.
-+
-+Child nodes as per the generic SPI binding.
-+
-+Example:
-+
-+	spi@b00 {
-+		compatible = "ralink,rt2880-spi";
-+		reg = <0xb00 0x100>;
-+
-+		#address-cells = <1>;

-
-The Ralink RT3883 SoCs have a built-in PCI Host Controller
-device. The patch adds a platform driver and device tree
-binding documentation for that.
-
-The patch also enables the HW_HAS_PCI config option. This
-is required in order to be able to enable the PCI support.

-+* Mediatek/Ralink RT3883 PCI controller
-+
-+1) Main node
-+
-+   Required properties:
-+
-+   - compatible: must be "ralink,rt3883-pci"
-+
-+   - reg: specifies the physical base address of the controller and
-+     the length of the memory mapped region.
-+
-+   - #address-cells: specifies the number of cells needed to encode an
-+     address. The value must be 1.
-+
-+   - #size-cells: specifies the number of cells used to represent the size
-+     of an address. The value must be 1.
-+
-+   - ranges: specifies the translation between child address space and parent
-+     address space
-+
-+  Optional properties:
-+
-+   - status: indicates the operational status of the device.
-+     Value must be either "disabled" or "okay".
-+
-+2) Child nodes
-+
-+   The main node must have two child nodes which describes the built-in
-+   interrupt controller and the PCI host bridge.
-+
-+   a) Interrupt controller:
-+
-+   Required properties:
-+
-+   - interrupt-controller: identifies the node as an interrupt controller
-+
-+   - #address-cells: specifies the number of cells needed to encode an
-+     address. The value must be 0. As such, 'interrupt-map' nodes do not
-+     have to specify a parent unit address.
-+
-+   - #interrupt-cells: specifies the number of cells needed to encode an
-+     interrupt source. The value must be 1.
-+
-+   - interrupt-parent: the phandle for the interrupt controller that
-+     services interrupts for this device.
-+
-+   - interrupts: specifies the interrupt source of the parent interrupt
-+     controller. The format of the interrupt specifier depends on the
-+     parent interrupt controller.
-+
-+   b) PCI host bridge:
-+
-+   Required properties:
-+
-+   - #address-cells: specifies the number of cells needed to encode an
-+     address. The value must be 0.
-+
-+   - #size-cells: specifies the number of cells used to represent the size
-+     of an address. The value must be 2.
-+
-+   - #interrupt-cells: specifies the number of cells needed to encode an
-+     interrupt source. The value must be 1.
-+
-+   - device_type: must be "pci"
-+
-+   - bus-range: PCI bus numbers covered
-+
-+   - ranges: specifies the ranges for the PCI memory and I/O regions
-+
-+   - interrupt-map-mask,
-+   - interrupt-map: standard PCI properties to define the mapping of the
-+     PCI interface to interrupt numbers.
-+
-+   The PCI host bridge node migh have additional sub-nodes representing
-+   the onboard PCI devices/PCI slots. Each such sub-node must have the
-+   following mandatory properties:
-+
-+     - reg: used only for interrupt mapping, so only the first four bytes
-+       are used to refer to the correct bus number and device number.
-+
-+     - device_type: must be "pci"
-+
-+   If a given sub-node represents a PCI bridge it must have following
-+   mandatory properties as well:
-+
-+     - #address-cells: must be set to <3>
-+
-+     - #size-cells: must set to <2>
-+
-+     - #interrupt-cells: must be set to <1>
-+
-+     - interrupt-map-mask,
-+     - interrupt-map: standard PCI properties to define the mapping of the
-+       PCI interface to interrupt numbers.
-+
-+   Besides the required properties the sub-nodes may have these optional
-+   properties:
-+
-+     - status: indicates the operational status of the sub-node.
-+       Value must be either "disabled" or "okay".
-+
-+3) Example:
-+
-+   a) SoC specific dtsi file:
-+
-+	pci@10140000 {
-+		compatible = "ralink,rt3883-pci";
-+		reg = <0x10140000 0x20000>;
-+		#address-cells = <1>;
-+		#size-cells = <1>;
-+		ranges; /* direct mapping */
-+
-+		status = "disabled";
-+
-+		pciintc: interrupt-controller {
-+			interrupt-controller;
-+			#address-cells = <0>;
-+			#interrupt-cells = <1>;
-+
-+			interrupt-parent = <&cpuintc>;
-+			interrupts = <4>;
-+		};
-+
-+		host-bridge {
-+			#address-cells = <3>;
-+			#size-cells = <2>;
-+			#interrupt-cells = <1>;
-+
-+			device_type = "pci";
-+
-+			bus-range = <0 255>;
-+			ranges = <
-+				0x02000000 0 0x00000000 0x20000000 0 0x10000000 /* pci memory */

-+			>;
-+
-+			interrupt-map-mask = <0xf800 0 0 7>;
-+			interrupt-map = <
-+				/* IDSEL 17 */
-+				0x8800 0 0 1 &pciintc 18

-+				0x9000 0 0 1 &pciintc 19
-+				0x9000 0 0 2 &pciintc 19
-+				0x9000 0 0 3 &pciintc 19
-+				0x9000 0 0 4 &pciintc 19
-+			>;
-+
-+			pci-bridge@1 {
-+				reg = <0x0800 0 0 0 0>;
-+				device_type = "pci";
-+				#interrupt-cells = <1>;
-+				#address-cells = <3>;
-+				#size-cells = <2>;
-+
-+				interrupt-map-mask = <0x0 0 0 0>;
-+				interrupt-map = <0x0 0 0 0 &pciintc 20>;
-+
-+				status = "disabled";
-+			};
-+
-+			pci-slot@17 {
-+				reg = <0x8800 0 0 0 0>;
-+				device_type = "pci";
-+
-+				status = "disabled";
-+			};
-+
-+			pci-slot@18 {
-+				reg = <0x9000 0 0 0 0>;
-+				device_type = "pci";
-+
-+				status = "disabled";
-+			};
-+		};
-+	};
-+
-+   b) Board specific dts file:
-+
-+	pci@10140000 {
-+		status = "okay";
-+
-+		host-bridge {
-+			pci-bridge@1 {
-+				status = "okay";
-+			};
-+		};

-Subject: [PATCH 117/133] NET: add of_get_mac_address_mtd()
-
-Many embedded devices have information such as mac addresses stored inside mtd
-devices. This patch allows us to add a property inside a node describing a
-network interface. The new property points at a mtd partition with an offset
-where the mac address can be found.

-+ * Gadget Zero only needs two bulk endpoints, and is an example of how you

-+ *
-+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
-+ * affect most of the driver.
-+ *
-+ * Use it with the Linux host/master side "usbtest" driver to get a basic
-+ * functional test of your device-side usb stack, or with "usb-skeleton".
-+ *
-+ * It supports two similar configurations.  One sinks whatever the usb host
-+ * writes, and in return sources zeroes.  The other loops whatever the host
-+ * writes back, so the host can read it.  Module options include:
-+ *
-+ *   buflen=N		default N=4096, buffer size used
-+ *   qlen=N		default N=32, how many buffers in the loopback queue
-+ *   loopdefault	default false, list loopback config first
-+ *
-+ * Many drivers will only have one configuration, letting them be much
-+ * simpler if they also don't support high speed operation (like this

-+ * The Core Interface Layer provides basic services for accessing and

-+ * Host Controller Driver and the Peripheral Controller Driver.
-+ *
-+ * The CIL manages the memory map for the core so that the HCD and PCD
-+ * don't have to do this separately. It also handles basic tasks like
-+ * reading/writing the registers and data FIFOs in the controller.
-+ * Some of the data access functions provide encapsulation of several
-+ * operations required to perform a task, such as writing multiple
-+ * registers to start a transfer. Finally, the CIL performs basic
-+ * services that are not specific to either the host or device modes
-+ * of operation. These services include management of the OTG Host
-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.
-+ *
-+ * The Core Interface Layer has the following requirements:
-+ * - Provides basic controller operations.
-+ * - Minimal use of OS services.
-+ * - The OS services used will be abstracted by using inline functions

-+/** @file
-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_driver_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM platform_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This
-+ * has the benefit that Linux can expose attributes of the driver and device
-+ * in its special sysfs file system. Users can then read or write files in
-+ * this file system to perform diagnostics on the driver components or the
-+ * device.

-+ * This file implements the Peripheral Controller Driver.
-+ *
-+ * The Peripheral Controller Driver (PCD) is responsible for
-+ * translating requests from the Function Driver into the appropriate
-+ * actions on the DWC_otg controller. It isolates the Function Driver
-+ * from the specifics of the controller by providing an API to the
-+ * Function Driver.
-+ *
-+ * The Peripheral Controller Driver for Linux will implement the
-+ * Gadget API, so that the existing Gadget drivers can be used.
-+ * (Gadget Driver is the Linux terminology for a Function Driver.)
-+ *
-+ * The Linux Gadget API is defined in the header file
-+ * <code><linux/usb_gadget.h></code>.  The USB EP operations API is
-+ * defined in the structure <code>usb_ep_ops</code> and the USB
-+ * Controller API is defined in the structure
-+ * <code>usb_gadget_ops</code>.
-+ *
-+ * An important function of the PCD is managing interrupts generated
-+ * by the DWC_otg controller. The implementation of the DWC_otg device
-+ * mode interrupt service routines is in dwc_otg_pcd_intr.c.
-+ *
-+ * @todo Add Device Mode test modes (Test J mode, Test K mode, etc).
-+ * @todo Does it work when the request size is greater than DEPTSIZ
-+ * transfer size

-+ * @file
-+ *
-+ * This file contains the data structures for accessing the DWC_otg core registers.
-+ *
-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they
-+ * would be after a power-on reset.

-Subject: [PATCH 126/133] spi: introduce macros to set bits_per_word_mask
-
-Introduce two macros to make setting up spi_master.bits_per_word_mask
-easier, and avoid mistakes like writing BIT(n) instead of BIT(n - 1).
-
-SPI_BPW_MASK is for a single supported value of bits_per_word_mask.
-
-SPI_BPW_RANGE_MASK represents a contiguous set of bit lengths.

-+Ethtool readme for selecting different PHY address.
-+
-+Before doing any ethtool command you should make sure the current PHY
-+address is expected. The default PHY address is 1(port 1).
-+
-+You can change current PHY address to X(0~4) by doing follow command:
-+# echo X > /proc/rt2880/gmac
-+
-+Ethtool command also would show the current PHY address as following.
-+
-+# ethtool  eth2
-+Settings for eth2:
-+        Supported ports: [ TP MII ]
-+        Supported link modes:   10baseT/Half 10baseT/Full
-+                                100baseT/Half 100baseT/Full
-+        Supports auto-negotiation: Yes
-+        Advertised link modes:  10baseT/Half 10baseT/Full
-+                                100baseT/Half 100baseT/Full
-+        Advertised auto-negotiation: No
-+        Speed: 10Mb/s
-+        Duplex: Full
-+        Port: MII
-+        PHYAD: 1
-+        Transceiver: internal
-+        Auto-negotiation: off
-+        Current message level: 0x00000000 (0)
-+        Link detected: no
-+
-+
-+The "PHYAD" field shows the current PHY address.
-+
-+
-+
-+Usage example
-+1) show port1 info
-+# echo 1 > /proc/rt2880/gmac		# change phy address to 1
-+# ethtool eth2
-+
-+2) show port0 info
-+# echo 0 > /proc/rt2880/gmac		# change phy address to 0
-+# ethtool eth2
