[PATCH 7/8] arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices

Tony Prisk
2012-08-08T01:41:20Z

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.
