Subject: [PATCH V3 0/2] firmware: arm_scmi: Register and handle limits change notification

This series registers for scmi limits change notifications to determine
the throttled frequency and apply HW pressure.

V3:
* Sanitize range_max received from the notifier. [Pierre]
* Drop patches 1/2 from v2. [Cristian]
* Update commit message in patch 2.

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

Depends on:
HW pressure v5: https://patchwork.kernel.org/project/linux-arm-msm/cover/20240220145947.1107937-1-vincent.guittot@linaro.org/
boost frequency support: https://patchwork.kernel.org/project/linux-arm-msm/cover/20240227173434.650334-1-quic_sibis@quicinc.com/

Sibi Sankar (2):
  cpufreq: Export cpufreq_update_pressure
  cpufreq: scmi: Register for limit change notifications
