This patch series adds support for CPR on MSM8916. The first patch exposes a corner voting API to the CPR driver so that we can change the corner for the MX regulator. If possible I would like to make this patch prettier, but I don't have any great ideas right now. The next patch adds support to adjust voltages in the OPP layer, and then hooks that up to cpufreq-dt so that we can adjust the voltage in response to what CPR tells us to do. I've also thrown in a patch to make RCU lockdep warnings go away, but I'm not sure if it's right. There's still work to do. The final patch adds the CPR driver. This still has some rough edges. With the OPPv2 bindings I'm thinking of moving the frequency tables into DT and adding a custom vendor property to describe which fuse corner to use for each frequency. Once you have these patches in place along with a CPU clock driver you can eanble enable cpufreq-dt and add the cpufreq-dt device (maybe the CPR driver should add the cpufreq-dt device?) and you'll see interrupts for CPR and OPP voltage adjustments triggering CPUfreq to modify voltages. Andy Gross (1): regulator: smd: Add floor and corner operations Stephen Boyd (4): PM / OPP: Support adjusting OPP voltages at runtime OPP: Allow notifiers to call dev_pm_opp_get_{voltage,freq} RCU-free cpufreq-dt: Handle OPP voltage adjust events power: avs: Add support for CPR (Core Power Reduction)From the responses so far I gather there will be a v3?
