[PATCH v2 1/3] dt-bindings: display: rockchip: Add schema for RK3588 HDMI TX Controller
Posted by Cristian Ciocaltea 1 year, 6 months ago
Rockchip RK3588 SoC integrates the Synopsys DesignWare HDMI 2.1
Quad-Pixel (QP) TX controller IP.

Since this is a new IP block, quite different from those used in the
previous generations of Rockchip SoCs, add a dedicated binding file.

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

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.

This is because the referenced synopsys,dw-hdmi-qp.yaml is provided by a
separate patchset:

So you made things untestable. No, this must be one patchset. Do not
send some library/helper and users of it in separate patchsets.
