Makes sense.

Can, please propose a separate series if you want to pursue the effort.
Also, I'd say that instead of moving the tables to a header (which defeats the
purpose of the header), the tables can be moved to a separate .c file. Like,

phy-qcom-qmp-ufs-tables.c
phy-qcom-qmp-ufs.c

Btw, why do we have "phy-qcom" prefix inside drivers/phy/qualcomm/?
