[PATCH V2 11/13] devfreq: tegra30: Migrate to dev_pm_opp_set_opp()

From: Viresh Kumar <viresh.kumar@linaro.org>
Date: 2021-01-27 09:16:55
Also in: linux-tegra, lkml
Subsystem: device frequency (devfreq), memory frequency scaling drivers for nvidia tegra, the rest · Maintainers: MyungJoo Ham, Kyungmin Park, Chanwoo Choi, Dmitry Osipenko, Linus Torvalds

dev_pm_opp_set_bw() is getting removed and dev_pm_opp_set_opp() should
be used instead. Migrate to the new API.

We don't want the OPP core to manage the clk for this driver, migrate to
dev_pm_opp_of_add_table_noclk() to make sure dev_pm_opp_set_opp()
doesn't have any side effects.

Dmitry,

This is based over the patches sent here:

https://lore.kernel.org/lkml/6c2160ff30a8f421563793020264cf9f533f293c.1611738228.git.viresh.kumar@linaro.org/ (local)

This should fix the problem you mentioned earlier. Will push this for
linux-next unless you have any issues with it.
