From: Yuanjie Yang <yuanjie.yang@oss.qualcomm.com>
Kaanapali introduces DPU 13.0.0 and DSI 2.10. Compared to SM8750,
Kaanapali has significant register changes, making it incompatible
with SM8750. So add MDSS/MDP display subsystem for Qualcomm Kaanapali.

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.

Because DT_SCHEMA_FILES excludes display/msm/dsi-phy-7nm.yaml. Soon (in the next linux-next tree), you can do: make display/msm/qcom,kaanapali-mdss.yaml Which will test the example in the specified schema against all schemas. Rob
