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.

Very probably only the number matters on this device. Therefore minimum and maximum should suffice. (Or an enum. 3 is probably an invalid number of lanes here, too.)

I heard rumour that it 'might' be possible to support 2 lanes, but I haven't seen any documentation for that and I don't think it's likely expected to be supported. -- Kieran > > -- > Kind regards, > > Sakari Ailus > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
