+ built with USB support.
+
+ The values are taken from the Ralink SDK Kernel.

+Subject: [PATCH 34/57] 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.

++
++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

++ * Gadget Zero only needs two bulk endpoints, and is an example of how you
++ * can write a hardware-agnostic gadget driver running inside a USB device.
++ *
++ * 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
++ * driver does).

++/** @file
++ *
++ * The Core Interface Layer provides basic services for accessing and
++ * managing the DWC_otg hardware. These services are used by both the
++ * 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
++ * or macros.

++ * 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

++ * 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.

++Ralink SoC GPIO controller bindings
++
++Required properties:
++- compatible:
++ - "ralink,rt2880-gpio" for Ralink controllers
++- #gpio-cells : Should be two.
++ - first cell is the pin number
++ - second cell is used to specify optional parameters (unused)
++- gpio-controller : Marks the device node as a GPIO controller
++- reg : Physical base address and length of the controller's registers
++- interrupt-parent: phandle to the INTC device node
++- interrupts : Specify the INTC interrupt number
++- ralink,num-gpios : Specify the number of GPIOs
++- ralink,register-map : The register layout depends on the GPIO bank and actual
++ SoC type. Register offsets need to be in this order.
++ [ INT, EDGE, RENA, FENA, DATA, DIR, POL, SET, RESET, TOGGLE ]
++
++Optional properties:
++- ralink,gpio-base : Specify the GPIO chips base number
++
++Example:
++
++ gpio0: gpio@600 {
++ compatible = "ralink,rt5350-gpio", "ralink,rt2880-gpio";
++
++ #gpio-cells = <2>;
++ gpio-controller;
++
++ reg = <0x600 0x34>;
++
++ interrupt-parent = <&intc>;
++ interrupts = <6>;
++
++ ralink,gpio-base = <0>;
++ ralink,num-gpios = <24>;
++ ralink,register-map = [ 00 04 08 0c
++ 20 24 28 2c
++ 30 34 ];

++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>;
