Currently, users of Mediatek OD (display overdrive) DT bindings set mediatek,gce-client-reg node property, which is missing from the DT schema. For example, device tree arch/arm64/boot/dts/mediatek/mt8173.dtsi is causing the following dtb check error: ``` $ make CHECK_DTBS=y mediatek/mt8173-elm.dtb SCHEMA Documentation/devicetree/bindings/processed-schema.json DTC [C] arch/arm64/boot/dts/mediatek/mt8173-elm.dtb [...] arch/arm64/boot/dts/mediatek/mt8173-elm.dtb: od@14023000 (mediatek,mt8173-disp-od): 'mediatek,gce-client-reg' does not match any of the regexes: '^pinctrl-[0-9]+$' ``` This commit adds the missing node property in the DT schema and updates the example as well.
