+Subject: [PATCH 08/53] 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.

++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>;
++ #size-cells = <0>;
++
++ m25p80@0 {
++ compatible = "m25p80";
++ reg = <0>;
++ spi-max-frequency = <10000000>;
++ };
++ };
