Instead of having separate implementations for all of them, where all will eventually lack something or the other, lets try to implement a common solution for everyone. This takes care of setting regulators, bw, required opps, etc for all device types. Dmitry, please go ahead and try this series. This is based of opp tree's linux-next branch. Sibi, since you added dev_pm_opp_set_bw() earlier, it would be good if you can give this a try. In case this breaks anything for you. I have already tested this on hikey board for CPU devices. To get this tested better and as early as possible, I have pushed it here: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/linux-next This will be part of linux-next tomorrow. Note, all the patches need to go through OPP tree here. Please provide your Acks for platform specific bits. -- Viresh Viresh Kumar (13): opp: Rename _opp_set_rate_zero() opp: No need to check clk for errors opp: Keep track of currently programmed OPP opp: Split _set_opp() out of dev_pm_opp_set_rate() opp: Allow _set_opp() to work for non-freq devices opp: Allow _generic_set_opp_regulator() to work for non-freq devices opp: Allow _generic_set_opp_clk_only() to work for non-freq devices opp: Update parameters of _set_opp_custom() opp: Implement dev_pm_opp_set_opp() cpufreq: qcom: Migrate to dev_pm_opp_set_opp() devfreq: tegra30: Migrate to dev_pm_opp_set_opp() drm: msm: Migrate to dev_pm_opp_set_opp() opp: Remove dev_pm_opp_set_bw() drivers/cpufreq/qcom-cpufreq-hw.c | 2 +- drivers/devfreq/tegra30-devfreq.c | 2 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 8 +- drivers/opp/core.c | 314 ++++++++++++++------------ drivers/opp/opp.h | 2 + include/linux/pm_opp.h | 6 +- 6 files changed, 184 insertions(+), 150 deletions(-) -- 2.25.0.rc1.19.g042ed3e048af
