[PATCH 3/8] ARM: MCS814x: add Device Tree bindings documentation

[Florian Fainelli]

This patch adds the device tree bindings documentation for the basic
Moschip MCS814x bindings that we support:
- soc
- interrupt controller
- timer
- pci controller

+Moschip MCS814x interrupt controller bindings
+----------------------------------------------
+
+Required properties:
+- compatible: should be "moschip,mcs814x-intc"
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: the number of cells to define the interrupts. Should be 1.
+The cells are the IRQ number
+- reg: contains the base address register and length, there should be only 1
+  cell
+
+Example:
+	intc: interrupt-controller at 400e4000 {
+		compatible = "moschip,mcs814x-intc";
+		interrupt-controller;
+		#interrupt-cells = <1>;
+		reg = <0x400e4000 0x48>;
+	};

+Moschip MCS814x PCI controller bindings
+---------------------------------------
+
+Required properties:
+- compatible: should be "moschip,mcs814x-pci"
+- reg: should contain the base register address and length of the PCI controller
+  configuration register as well as the base register address and length of the
+  PCI eeprom emulator
+- interrupts: should contain the interrupt line of the abort interrupt
+- #address-cells: should be 3
+- #size-cells: should be 2
+- ranges: should contain the properly encoded PCI ranges of the IO, non-prefetchable
+  and prefetchable memory regions
+- #interrupt-cells: should be 1
+- interrupt-map-mask: should be 0
+- interrupt-map: should be the properly encoded PCI slot/pin to interrupt line
