[PATCH v2 07/13] dt-bindings: display: sun4i: Add binding for A31 HDMI controller

Show all headers | View raw

The HDMI controller in the A31 SoC is slightly different from the
earlier version. In addition to the TMDS clock and DDC controls,
this version now takes a second DDC clock input.

Add a compatible string for it, and add the DDC clock input to the
list of clocks required.
