Add a PHY configuration sequence for the sdm845 which uses a Qualcomm

The PHY can be configured as two phase or three phase in C-PHY or D-PHY

too much or, according to my understand D-PHY use 2 phase, C-PHY use 3
phase?

The PHY can be configured as two phase (D-PHY) or three phase (C-PHY) ?
Yes, I'll address the wrong wording in the next version then 🙂

Can you look at what's required to convert to the new driver ?

I think some Linux plumbing to represent cphy v dphy to the phy subsystem might be nice, plus differentiating inside of the new driver and camss with media-graph used to find the PHY.
