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.

Wave521c has capability to use SRAM carveout to store reference data with purpose of reducing memory bandwidth. To properly use this pool, the driver expects to have an sram and sram-size node. Without sram-size node, driver will default value to zero, making sram node irrelevant.
