- scaling
-
- If the USB HCD is running and the cpu is scaled too low, then the USB stops

-Subject: [PATCH 47/57] GPIO: MIPS: ralink: add gpio driver for ralink SoC
-
-Add gpio driver for Ralink SoC. This driver makes the gpio core on
-RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

-+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 {

-From: Jonas Gorski <jogo@openwrt.org>
-Date: Mon, 25 May 2015 16:51:34 +0200
-Subject: [PATCH] MIPS: ralink: fix clearing the illegal access interrupt
-
-Due to a typo the illegal access interrupt is never cleared in by
-the interupt handler, causing an effective deadlock on the first
-illegal access.
-
-This was broken since the code was introduced in 5433acd81e87 ("MIPS:
-ralink: add illegal access driver"), but only exposed when the Kconfig
-symbol was added, thus enabling the code.
-
-Cc: <stable@vger.kernel.org> [3.18+]
-Fixes: a7b7aad383c ("MIPS: ralink: add missing symbol for RALINK_ILL_ACC")
-Signed-off-by: Jonas Gorski <jogo@openwrt.org>

-Subject: [OpenWrt-Devel,RFC] A patch for mt7621 nand controler. Revision 2.
-From: Kirill Berezin <fyiwdt@gmail.com>
-X-Patchwork-Id: 544092
-Message-Id: <CAOFwh=DZieEa4ZA0ex6G3OR2OgEeP6Fh+SSw=Zg-L0wWm1QRTA@mail.gmail.com>

-
-Hello,
-
-It turned out that mtk_nand driver uses some sophisticated accounting and a
-general nand code must be patched.
-
-This patch adds required read and erase calls to a general nand code. I
-used a code for re6500 released by Linksys as a reference.
-
-All required operations (erase, write and read) are usable. However I found
-that jffs2 filesystem can be created only on top of a ubi volume. I tried
-to create jffs2 directly on mtd device but pages with clean markers are
-became uncorrectable.
-
-This patch also includes changes that I sent earlier.
-
-Best regards,
-Kirill.

+ 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";

++I2C for Ralink platforms
++
++Required properties :
++- compatible : Must be "link,rt3052-i2c"
++- reg: physical base address of the controller and length of memory mapped
++ region.
++- #address-cells = <1>;
++- #size-cells = <0>;
++
++Optional properties:
++- Child nodes conforming to i2c bus binding
++
++Example :
++
++palmbus@10000000 {
++ i2c@900 {
++ compatible = "link,rt3052-i2c";
++ reg = <0x900 0x100>;

++ #size-cells = <0>;
++
++ hwmon@4b {
