arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices
Bindings for gpio, interrupt controller, power management controller, timer, realtime clock, serial uart, ehci and uhci controllers and framebuffer controllers used on the arch-vt8500 platform. Framebuffer binding also specifies a 'display' node which is required for determining the lcd panel data. Signed-off-by: Tony Prisk <linux@prisktech.co.nz>

1VIA/Wondermedia VT8500 GPIO Controller
2-----------------------------------------------------
3
4Required properties:
5- compatible : "via,vt8500-gpio", "wm,wm8505-gpio"
6 or "wm,wm8650-gpio" depending on your SoC
7- reg : Should contain 1 register range (address and length)
8- #gpio-cells : should be <3>.
9 1) bank
10 2) pin number
11 3) flags - should be 0
12
13Example:
14
15 gpio: gpio-controller@d8110000 {
16 compatible = "via,vt8500-gpio";
17 gpio-controller;
18 reg = <0xd8110000 0x10000>;
19 #gpio-cells = <3>;
20 };
21
22 vibrate {
23 gpios = <&gpio 0 1 0>; /* Bank 0, Pin 1, No flags */
24 };
