Is this regulator really always on?
This feeds on to RTC which is a free running clock. So i guess always on is
justified no?
Well the dts entries should describe the hardware. If the
regulator can be enabled and disabled, we should not claim it's
always on.
From the PMIC perspective every regulator can be enabled and
disabled. From a Board perspective there are some which need
to be always on. For Ex: SMPS123 which feeds on to the MPU.
I guess RTC also needs the supply to be on as long as we want
the clock to be ticking.
Also adding temporary dts entries just causes more churn on the
dts files which is a PITA for everybody.
