Looking at the component documentation and the schematics I think the
component is "PMM8155AU" and we have two of them.

Unless I'm mistaken we should have the compatible describe the single
component and we should have DT describe the fact that we have 2 of
them.

If we refer to the PM8155AU device specifications, there are two
regulators mentioned there PMM8155AU_1 and PMM8155AU_2. Although most
parameters of the regulators seem similar the smps regulator summary
for both appear different (Transient Load, mA ratings etc).

Although most of these differences don't probably matter to the Linux
world, others like the gpios on the pmic are different.

So, IMO, it makes sense to mention the different pmic types on the board.

Please let me know your views on the same.

Thanks,
Bhupesh
