I guess this is dead, but I'll comment here anyway because this issue has come up several times and I think something is needed. > > Signed-off-by: Peter Rosin <p...@axentia.se> > --- > .../bindings/display/bridge/lvds-transmitter.txt | 6 ++++++ > drivers/gpu/drm/bridge/lvds-encoder.c | 25 > ++++++++++++++++++++++ > 2 files changed, 31 insertions(+) > > diff --git > a/Documentation/devicetree/bindings/display/bridge/lvds-transmitter.txt > b/Documentation/devicetree/bindings/display/bridge/lvds-transmitter.txt > index 50220190c203..8d40a2069252 100644 > --- a/Documentation/devicetree/bindings/display/bridge/lvds-transmitter.txt > +++ b/Documentation/devicetree/bindings/display/bridge/lvds-transmitter.txt > @@ -30,6 +30,12 @@ Required properties: > device-specific version corresponding to the device first > followed by the generic version. > > +Optional properties: > + > +- interface-pix-fmt: > + List of valid input bus formats of the encoder.

It's the same problem though the bus/pixel formats are somewhat different. "bus-width" is probably enough to handle your particular case, but I'd imagine that could easily not be the case. If so, we should extend the existing binding rather than diverge with something new.
