Update the binding to accommodate this usage by introducing a data-lanes and a mode-switch property on endpoints. Also include the link to the product brief in the bindings. Signed-off-by: Pin-yen Lin --- Changes in v7: - Fixed issues reported by dt_binding_check - Updated the schema and the example dts for data-lanes. - Changed to generic naming for the example dts node. Changes in v6: - Remove switches node and use endpoints and data-lanes property to describe the connections. .../display/bridge/analogix,anx7625.yaml | 101 +++++++++++++++++- 1 file changed, 98 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.yaml b/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.yaml index 4590186c4a0b..536dbe8eaf60 100644 --- a/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.yaml +++ b/Documentation/devicetree/bindings/display/bridge/analogix,anx7625.yaml @@ -12,7 +12,8 @@ maintainers: description: | The ANX7625 is an ultra-low power 4K Mobile HD Transmitter - designed for portable devices. + designed for portable devices.
