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>

+VIA VT8500 Framebuffer
+-----------------------------------------------------
+
+Required properties:
+- compatible : "via,vt8500-fb"
+- reg : Should contain 1 register ranges(address and length)
+- interrupts : framebuffer controller interrupt
+- display: a phandle pointing to the display node
+
+Required nodes:
+- display: a display node is required to initialize the lcd panel
+ This should be in the board dts.
+- default-mode: a videomode within the display with timing parameters
+ as specified below.
+
+Example:
+
+ fb@d800e400 {
+ compatible = "via,vt8500-fb";
+ reg = <0xd800e400 0x400>;
+ interrupts = <12>;
+ display = <&display>;
+ default-mode = <&mode0>;
+ };
+
+VIA VT8500 Display
+-----------------------------------------------------
+Required properties (as per of_videomode_helper):
+
+ - hactive, vactive: Display resolution
+ - hfront-porch, hback-porch, hsync-len: Horizontal Display timing parameters
+ in pixels
+ vfront-porch, vback-porch, vsync-len: Vertical display timing parameters in
+ lines
+ - clock: displayclock in Hz
+ - bpp: lcd panel bit-depth.
+ <16> for RGB565, <32> for RGB888
+
+Optional properties (as per of_videomode_helper):
+ - width-mm, height-mm: Display dimensions in mm
+ - hsync-active-high (bool): Hsync pulse is active high
+ - vsync-active-high (bool): Vsync pulse is active high
+ - interlaced (bool): This is an interlaced mode
+ - doublescan (bool): This is a doublescan mode
+
+Example:
+ display: display@0 {
+ modes {
+ mode0: mode@0 {
+ hactive = <800>;
+ vactive = <480>;
+ hback-porch = <88>;
+ hfront-porch = <40>;
+ hsync-len = <0>;
+ vback-porch = <32>;
+ vfront-porch = <11>;
+ vsync-len = <1>;
+ clock = <0>; /* unused but required */
+ bpp = <16>; /* non-standard but required */
+ };
+ };
+ };
