[PATCH v2 1/2] dt-bindings/display/bridge: sii902x: add optional power supplies

From: Philippe Cornu
Date: Wed Apr 25 2018 - 03:54:16 EST

Add optional power supplies using the description found in
"SiI9022A/SiI9024A HDMI Transmitter Data Sheet (August 2016)".

There is a single 1v2 supply voltage named vcc12 from which cvcc12
(digital core) and avcc12 (TMDS analog) are derived because according
to this data sheet:
"cvcc12 and avcc12 can be derived from the same power source"
