Hi Rob, Thank you for the patch.

Fair enough, but then shouldn't there be a comment in the data-lanes property to tell that i.MX7 only supports up to 2 data lanes ? > The error in this schema is masked by a fixup in the tools causing the > 'allOf' to get overwritten.

I'll add this to data-lanes: description: Note that 'fsl,imx7-mipi-csi2' only supports up to 2 data lines. I assume it is 1 or 2 and not only 2, right? Rob

The if/then schema for 'data-lanes' doesn't work as 'compatible' is at a different level than 'data-lanes'.
