A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Add a binding for the HDMI TX v2 Encoder found in MediaTek MT8195 and MT8188 SoCs. This fully supports the HDMI Specification 2.0b, hence it provides support for 3D-HDMI, Polarity inversion, up to 16 bits Deep Color, color spaces including RGB444, YCBCR420/422/444 (ITU601/ITU709) and xvYCC, with output resolutions up to 3840x2160p@60Hz. Moreover, it also supports HDCP 1.4 and 2.3, Variable Refresh Rate (VRR) and Consumer Electronics Control (CEC). This IP also includes support for HDMI Audio, including IEC60958 and IEC61937 SPDIF, 8-channel PCM, DSD, and other lossless audio according to HDMI 2.0.
