SoC specific compatible.


This is a generic Module Power Manager Sleep Counter which is present in
all Qcom Socs, so SoC specific compatible is not given here.

Not really a good reason and it is actually very difficult to verify
this. If I understand correctly any moment FW can change and this will
stop being valid, so no.

Since this does not have clocks, what frequency you are setting here?

Module Power Manager(MPM) Sleep Counter is a clock that starts ticking
from Primary Boot Loader(PBL) Stage. This is usually a 32 Khz clock and
the frequency for the same is stored here.

You just said all devices have the same MPM, so I would argue that all
devices have the same clock.

Anyway, this is a legacy property.

Ack. Will drop clock frequency.
