Hi Marek, Thank you for the patch. On Sat, May 15, 2021 at 10:46:55PM +0200, Marek Vasut wrote: > Decoder input LVDS format is a property of the decoder chip or even > its strapping.

The information could also be derived by the driver from the compatible string in the case when this is an intrinsic property of the device (or when it's configurable by software), but the fact that it can also be controlled by strapping makes a DT property needed. We may want to limit the usage of the DT property to the strapping case though, but I don't have a real preference here, so I'm fine with this approach. > Signed-off-by: Marek Vasut <marex@xxxxxxx> > Cc: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> > Cc: Rob Herring <robh+dt@xxxxxxxxxx> > Cc: Sam Ravnborg <sam@xxxxxxxxxxxx> > Cc: devicetree@xxxxxxxxxxxxxxx > To: dri-devel@xxxxxxxxxxxxxxxxxxxxx > --- > .../bindings/display/bridge/lvds-codec.yaml | 19 +++++++++++++++++++ > 1 file changed, 19 insertions(+) > > diff --git a/Documentation/devicetree/bindings/display/bridge/lvds-codec.yaml b/Documentation/devicetree/bindings/display/bridge/lvds-codec.yaml > index f4dd16bd69d2..f0abb94f8f2e 100644 > --- a/Documentation/devicetree/bindings/display/bridge/lvds-codec.yaml > +++ b/Documentation/devicetree/bindings/display/bridge/lvds-codec.yaml > @@ -64,6 +64,15 @@ properties: > - port@0 > - port@1 > > + data-mapping: > + enum: > + - jeida-18 > + - jeida-24 > + - vesa-24 > + description: | > + The color signals mapping order.

You can group them in a 'allOf' property. -- Regards, Laurent Pinchart
