[RFC PATCH 3/3] ARM: vexpress: configure CLCD driver device tree support for A9 CoreTile

Ryan Harkin ryan.harkin at linaro.org
Thu Sep 20 02:04:26 EST 2012


Configuration for the amba-clcd PL111 driver is added to the A9 CoreTile's DTS
file.

Configuration of the motherboard CLCD driver is removed from the DTSI files to
prevent duplicate CLCD drivers being registered.

A generic set of CLCD panel descriptions has been split into its own DTSI file.
Currently, only XVGA and VGA monitors are described.
