Subject: [PATCH 06/14] MIPS: ralink: adds OF code
Until there is a generic MIPS way of handing the DTB over from bootloader to
kernel we rely on a built in devicetrees. The OF code also remaps those register
ranges that we use global in our drivers.

+MIPS CPU interrupt controller
+
+On MIPS the mips_cpu_intc_init() helper can be used to initialize the 8 CPU
+IRQs from a devicetree file and create a irq_domain for IRQ controller.
+
+With the irq_domain in place we can describe how the 8 IRQs are wired to the
+platforms internal interrupt controller cascade.
+
+Below is an example of a platform describing the cascade inside the devicetree
+and the code used to load it inside arch_init_irq().
+
+Required properties:
+- compatible : Should be "mti,cpu-interrupt-controller"
+
+Example devicetree:
+ cpu-irq: cpu-irq@0 {
+ #address-cells = <0>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ compatible = "mti,cpu-interrupt-controller";
+ };
+
+ intc: intc@200 {
+ compatible = "ralink,rt2880-intc";
+ reg = <0x200 0x100>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&cpu-irq>;
+ interrupts = <2>;
+ };
+
+
+Example platform irq.c:
+static struct of_device_id __initdata of_irq_ids[] = {
+ { .compatible = "mti,cpu-interrupt-controller", .data = mips_cpu_intc_init },
+ { .compatible = "ralink,rt2880-intc", .data = intc_of_init },
+ {},
+};
+
+void __init arch_init_irq(void)

ralink wisoc
The MIPS based Ralink WiSoC platform has 1 or more 8250 compatible serial cores.
To make them work we require the same quirks that are used by AU1x00.

Add a dtsi file for RT5350 Soc. This SoC is almost the same as RT3050 but has
OHCI/EHCI in favour of the Synopsis DWC2 core.

From 9d13fedc08f4e2cd9640983c2af8b9e9c64c094b Mon Sep 17 00:00:00 2001

Subject: [PATCH 110/121] MIPS: add rt3883 dts files
Add a dtsi file for RT3883 SoC. This SoC is almost the same as RT3050 but has
OHCI/EHCI in favour of the Synopsis DWC2 core. There is also a 3x3 802.11n
wifi core.

Subject: [PATCH 201/208] owrt: OF: NET: add of_get_mac_address_mtd()
Many embedded devices have information such as mac addresses stored inside mtd
devices. This patch allows us to add a property inside a node describing a
network interface. The new property points at a mtd partition with an offset
where the mac address can be found.

Subject: [PATCH 204/208] owrt: MIPS: ralink: add usb platform support
Add code to load the platform ehci/ohci driver on Ralink SoC. For the usb core
to work we need to populate the platform_data during boot, prior to the usb
driver being loaded.

Subject: [PATCH 207/208] owrt: MIPS: ralink: add support for runtime memory
detection
This allows us to add a device_node called "memorydetect" to the DT with
information about the memory windoe of the SoC. Based on this the memory is
detected ar runtime.

The pinctrl node must have "#gpio-range-cells" property to show number of
arguments to pass with phandle from gpio controllers node.
+
+3) gpio-export
+--------------
+
+gpio-export will allow you to automatically export gpio
+
+required properties:
+- compatible: Should be "gpio-export"
+
+in each child node will reprensent a gpio or if no name is specified
+a list of gpio to export
+
+required properties:
+- gpios: gpio to export
+
+optional properties:
+ - gpio-export,name: export name
+ - gpio-export,output: to set the as output with default value
+ if no present gpio as input
+ - pio-export,direction_may_change: boolean to allow the direction to be controllable
+
+Example:
+
+
+gpio_export {
+ compatible = "gpio-export";
+ #size-cells = <0>;
+
+ in {
+ gpio-export,name = "in";
+ gpios = <&pioC 20 0>;
+ };
+
+ out {
+ gpio-export,name = "out";
+ gpio-export,output = <1>;
+ gpio-export,direction_may_change;
+ gpios = <&pioC 21 0>;
+ };
+
+ in_out {
+ gpio-export,name = "in_out";
+ gpio-export,direction_may_change;
+ gpios = <&pioC 21 0>;
