sam, This is my latest yaml file https://github.com/vinaysimhabn/kernel-msm/blob/5.6.0-rc3-d2l-wip/Documentation/devicetree/bindings/display/bridge/toshiba%2Ctc358775.yaml make CROSS_COMPILE=$TC64 ARCH=arm64 DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/bridge/toshiba,tc358775.yaml dt_binding_check i am getting these errors Documentation/devicetree/bindings/display/bridge/toshiba,tc358775.example.dt.yaml: lvds-out: 'data-mapping', 'height-mm', 'panel-timing', 'width-mm' do not match any of the regexes: 'pinctrl-[0-9]+' Documentation/devicetree/bindings/display/bridge/toshiba,tc358775.example.dt.yaml: lvds-out: compatible: Additional items are not allowed ('panel-lvds' was unexpected) Documentation/devicetree/bindings/display/bridge/toshiba,tc358775.example.dt.yaml: lvds-out: compatible: ['auo,b101xtn01', 'panel-lvds'] is too long Please suggest how to add the references of panel/lvds.yaml or panel/panel-common.yaml and panel/advantech,idk-2121wr.yaml in my yaml file.
