+Subject: [PATCH 23/57] MIPS: ralink: mt7620: fix usb issue during frequency
+ scaling
+
+ If the USB HCD is running and the cpu is scaled too low, then the USB stops
+ working. Increase the idle speed of the core to fix this if the kernel is
+ 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.

++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 ];

+
+Add gpio driver for Ralink SoC. This driver makes the gpio core on
+RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

++This SPI controller is found on most wireless SoCs made by ralink.

++Required properties:

++- 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.
