Thanks for your review. Does a new 'panel-simple-lvds-dual-ports.yaml' binding look ok? I assume it would inherit all properties of panel-simple.yaml and all existing compatibles of LVDS panels with dual ports in panel-simple.yaml can be moved to it. > a dedicated binding for the specific panel. > > I trust that if other readers of this mail disagrees with this > recommendation that they will speak up. > > Sam > > > Cc: Thierry Reding <thierry.red...@gmail.com> > > Cc: Sam Ravnborg <s...@ravnborg.org> > > Cc: David Airlie <airl...@linux.ie> > > Cc: Daniel Vetter <dan...@ffwll.ch> > > Cc: Rob Herring <robh...@kernel.org> > > Signed-off-by: Liu Ying <victor....@nxp.com> > > --- > > Documentation/devicetree/bindings/display/panel/panel-simple.yaml > > | 1 + > > 1 file changed, 1 insertion(+) > > > > diff --git a/Documentation/devicetree/bindings/display/panel/panel- > > simple.yaml > > b/Documentation/devicetree/bindings/display/panel/panel-simple.yaml > > index f9750b0..5ccb22b 100644 > > --- a/Documentation/devicetree/bindings/display/panel/panel- > > simple.yaml > > +++ b/Documentation/devicetree/bindings/display/panel/panel- > > simple.yaml > > @@ -288,6 +288,7 @@ properties: > > backlight: true > > enable-gpios: true > > port: true > > + ports: true > > power-supply: true > > > > additionalProperties: false > > -- > > 2.7.4 -- Liu Ying _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
