I appreciate your efforts to get this upstream, but this is not
how upstream development typically works. We usually iterate a patch
until all stakeholders are happy and then merge it.

So unless Rob changes its mind and gives his Reviewed-by for the
devicetree bits from this v5, then this cannot be merged as is.

Regards,

Hans
