What is the reason? > Your datasheet naming does not matter. Glymur CAMSS has populated inputs for CSIPHY0, CSIPHY1 and CSIPHY4, so I used a sparse pattern for those ports only. That is confusing for the schema. I will allow the continuous range port@0 through port@4 and keep the example limited to the populated Glymur ports. -- Regards, Nihal Kumar Gupta
