On SM8550, two sets of UFS PHY settings are provided, one set is to support
HS-G5, another set is to support HS-G4 and lower gears. The two sets of PHY
settings are programming different values to different registers, mixing
the two sets and/or overwriting one set with another set is definitely not
blessed by UFS PHY designers. In order to add HS-G5 support for SM8550, we
need to split the two sets into their dedicated tables, and leave only the
common settings in the .tlbs. To have the PHY programmed with the correct
set of PHY settings, the submode passed to PHY driver must be either HS-G4
or HS-G5.
I guess I'll need to rebase my SM8650 UFS PHY driver to support both G4 and G5 modes
at some point ?
