Trying to make my understanding clear.
eUSB repeater is a peripheral in the PMIC. Do we need a separate
compatible even if the peripheral is same in two different PMIC chips?
I believe eUSB peripheral has some identification registers to apply any
quirks in future.
Adding Jack who would know more about any deltas between the PMICs in
sdx75 and sm8550.
