drm/rockchip: Add driver for the new DSI2 controller

[PATCH 2/3] dt-bindings: display: rockchip: Add schema for RK3588 DW DSI2 controller

Posted by Heiko Stuebner 2 weeks, 3 days ago

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The Display Serial Interface 2 (DSI-2) is part of a group of communication
protocols defined by the MIPI Alliance. The RK3588 implements this
specification in its two MIPI DSI-2 Host Controllers that are based on a
new Synopsis IP.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/display/rockchip/rockchip,rk3588-mipi-dsi2.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20241106123304.422854-3-heiko@sntech.de

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.
