[PATCH V2 0/4] firmware: arm_scmi: Register and handle limits change notification

[Sibi Sankar]

This series registers for scmi limits change notifications and adds
perf_notify_support/perf_opp_xlate interfaces which are used by the
scmi cpufreq driver to determine the throttled frequency and apply HW
pressure.

V2:
* Rename opp_xlate -> freq_xlate [Viresh]
* Export cpufreq_update_pressure and use it directly [Lukasz]

Depends on:
HW pressure v4: https://patchwork.kernel.org/project/linux-arm-msm/cover/20240109164655.626085-1-vincent.guittot@xxxxxxxxxx/
