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

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/dma/mtk-cqdma.example.dt.yaml: dma-controller@...12000: '#dma-cells', 'dma-channel-mask' do not match any of the regexes: 'pinctrl-[0-9]+'


See https://patchwork.ozlabs.org/patch/1346576

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.
