Subject: [PATCH v2 1/4] dt-bindings: media: add mediatek ISP3.0 sensor interface

From: Louis Kuo <[email protected]>

This adds the bindings, for the mediatek ISP3.0 SENINF module embedded in
some Mediatek SoC, such as the mt8365

+description:
+ The ISP3.0 SENINF is the CSI-2 and parallel camera sensor interface found in
+ multiple MediaTek SoCs. It can support up to three physical CSI-2
+ input ports, configured in DPHY (2 or 4 data lanes) or CPHY depending on the SoC.
+ On the output side, SENINF can be connected either to CAMSV instance or
+ to the internal ISP. CAMSV is used to transfer the sensor data (Raw, YUV)
+ to DRAM directly, without internal ISP processing.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. 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.

Drop

Drop all this. Don't need to define endpoint as
/schemas/graph.yaml#/properties/port already does.

Same on other ports.
