Have a look here:
https://lore.kernel.org/all/CAA8EJpr8rKMBzcm-=HGu7-C5hPkNMrnG1cA78O00UjgJVT7p6Q@mail.gmail.com/
I currently implemented this locally, using the is-edp property.
Whatever property we will end up using for specifying the mode in the
controller mode, the set_mode op is still needed in the phy driver.
