Hi Rajendra,
I see lowest rpmhpd_opp_low_svs opp is for 75MHz. It is a bit higher
for a serial.
I am just curious about this.
I also want to confirm that the rpmhpd_opp_low_svs voltage restriction
is for serial
controller, not for clock controller? Because I see there is similar
restriction to clock
controller on another platform, the restriction is for branch clock,
not leaf clock that
consumer device will get.
