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.

Are you sure these are using same units? Old code used us. Your example: i2c-scl-clk-low-timeout-ms = <10000>; 10s timeout? Best regards, Krzysztof

The clock stretching goes in order of milliseconds and in any case doesn't need to be precisely that, as long as it's longer. I don't see any need for it to be us... if it 12500us, let it be 13ms. I will update the example. Can I keep your r-b with: i2c-scl-clk-low-timeout-ms = <10>; ? Thanks for noticing it, it would have been a wacky mistake, Andi
