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.

The DMA IP of Sophgo CV18XX/SG200X is based on a DW AXI CORE, with an additional channel remap register located in the top system control area. The DMA channel is exclusive to each core. In addition, the DMA multiplexer is a subdevice of system controller, so this binding only contains necessary properties for the multiplexer itself. Add the dmamux binding for CV18XX/SG200X series SoC.
