The ADV7510 is available and there's a pinout comparison with the 7511: http://www.analog.com/media/en/technical-documentation/evaluation-documentation/ADV7510_to_ADV7511_differences.pdf These 2 seem to have the same supplies... > > Cc: Rob Herring <robh@xxxxxxxxxx> > Cc: devicetree@xxxxxxxxxxxxxxx > Signed-off-by: Archit Taneja <architt@xxxxxxxxxxxxxx> > --- > Documentation/devicetree/bindings/display/bridge/adi,adv7511.txt | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/Documentation/devicetree/bindings/display/bridge/adi,adv7511.txt b/Documentation/devicetree/bindings/display/bridge/adi,adv7511.txt > index 6532a59..669b6f2 100644 > --- a/Documentation/devicetree/bindings/display/bridge/adi,adv7511.txt > +++ b/Documentation/devicetree/bindings/display/bridge/adi,adv7511.txt > @@ -56,6 +56,12 @@ Optional properties: > - adi,disable-timing-generator: Only for ADV7533.

The 7511 has DVDD, AVDD, and PVDD. > +- v1p2-supply: Only for ADV7533. A supply that powers up the V1P2 pin on the > + chip. Can be either 1.2V or 1.8V.

Not clear what the voltage is.
