Subject: [PATCH 06/53] MIPS: ralink: add cpu frequency scaling
This feature will break udelay() and cause the delay loop to have longer delays
when the frequency is scaled causing a performance hit.

+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 ];
+
+ };

Subject: [PATCH 27/53] 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.

Subject: [PATCH 2/3] phy: ralink-usb: add driver for Mediatek/Ralink
Add a driver to setup the USB phy on Mediatek/Ralink SoCs.
The driver is trivial and only sets up power and host mode.

+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 :

mtd: spi-nor: add support for switching between 3-byte and 4-byte addressing on w25q256 flash
On some devices the flash chip needs to be in 3-byte addressing mode during
reboot, otherwise the boot loader will fail to start.
This mode however does not allow regular reads/writes onto the upper 16M
half. W25Q256 has separate read commands for reading from >16M, however
it does not have any separate write commands.
This patch changes the code to leave the chip in 3-byte mode most of the
time and only switch during erase/write cycles that go to >16M
addresses.
