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@xxxxxxxxxxxxxx>
---
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
