Related to my comments on patch 16 [1], I believe this should be set
differently between DPHY and CPHY. As I test more cameras I've patched
this to allow CPHY link frequencies up to 2500MHz. I'm also wondering
whether these should be driver-specific rather than defined at the
framework level to allow for higher capacities in future silicon.
