[PATCH v2 3/6] ARM: dts: cm-t54: add HDMI/DVI display data

Wed Sep 17 05:10:05 PDT 2014


Add DSS related pinmux and display data nodes required to support HDMI
and DVI video out on CM-T54.

Signed-off-by: Dmitry Lifshitz <lifshitz at compulab.co.il>

v2: * Fixed comment style issue for mux mode.
      Follow the convention mode0_name.modeX_name for pins
      which mux mode differs from MUX_MODE0

    * Moved aliases node to the top of dts file
