Hi Randy,

Thanks for the patch.

Could GENERIC_PHY_MIPI_DPHY select GENERIC_PHY instead of depending it?

There seem to be a few other drivers that appear to have the same issue.

Yes, I don't see why not.  Let's see what the PHY framework people have to say about it.

Vinod, Kishon, do you see any reason that GENERIC_PHY_MIPI_DPHY could not select
GENERIC_PHY instead of depending on it?

Yes, I see 4 others that have the same issue.
