++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

++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>;

++Required properties :
++- compatible : Must be "link,rt3052-i2c"
++- reg: physical base address of the controller and length of memory mapped

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

++Optional properties:
++- 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.

+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
+physical cores, which leads to a hang on SMP bringup.
+Add a hack to detect missing cores.
