This patch fixes the following bugs in the original yaml conversion: - Fixed dependency between 'data-lanes' and 'lane-polarities', which was backwards. Now you can only specify 'lane-polarities' if you specified 'data-lanes'. I could have sworn I tried this before. - We can't remap input lanes in this hardware. This patch doesn't do, but if someone knew how I'd love to: - Make sure if we have both 'lane-polarities' and 'data-lanes' that they have the same number of elements. Signed-off-by: Douglas Anderson --- This patch could be squashed atop the patch adding the yaml [1]. I'm sending separately for now to avoid churning the series another time.
