-+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>;

-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.

-+Ralink SoC RT2880 SPI master controller.

-+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.

-+Child nodes as per the generic SPI binding.

-+ #address-cells = <1>;

-+Required properties :

-+- reg: physical base address of the controller and length of memory mapped

-+- #address-cells = <1>;

-+- Child nodes conforming to i2c bus binding

-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.

-Make the behaviour of clk_get_rate consistent with common clk's
-clk_get_rate by accepting NULL clocks as parameter. Some device
-drivers rely on this, and will cause an OOPS otherwise.

-There is a variant of MT7621 which contains only one CPU core instead of 2.
-This is not reflected in the config register, so the kernel detects more

-Add a hack to detect missing cores.
