[PATCH 0/3] OPP: Simplify set_required_opp handling

From: Viresh Kumar
Date: Wed Feb 22 2023 - 06:07:07 EST


Hello,

The required-opps configuration is closely tied to genpd and performance
states at the moment and it is not very obvious that required-opps can
live without genpds. Though we don't support configuring required-opps
for non-genpd cases currently.

This patchset aims at cleaning up this a bit, just like what's done for clk and
regulators. This also makes it possible for platforms to provide their own
version of set_required_opps() helper, which can be used to configure the
devfreq device propertly.

Jun,

I haven't found time to test this through yet, though there isn't much anyway I
guess. Can you see if these can solve your problem properly ?

OPP: Handle all genpd cases together in _set_required_opps()
OPP: Move required opps configuration to specialized callback
OPP: Allow platforms to add a set_required_opps() callback
