Merge tag 'pm-5.18-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These update ARM cpufreq drivers, the OPP (Operating Performance Points) library and the power management documentation. Specifics: - Add per core DVFS support for QCom SoC (Bjorn Andersson), convert to yaml binding (Manivannan Sadhasivam) and various other fixes to the QCom drivers (Luca Weiss). - Add OPP table for imx7s SoC (Denys Drozdov) and minor fixes (Stefan Agner). - Fix CPPC driver's freq/performance conversions (Pierre Gondois). - Minor generic cleanups (Yury Norov). - Introduce opp-microwatt property to the OPP core, bindings, etc (Lukasz Luba). - Convert DT bindings to schema format and various related fixes (Yassine Oudjana). - Expose OPP's OF node in debugfs (Viresh Kumar). - Add Intel uncore frequency scaling documentation file to its MAINTAINERS entry (Srinivas Pandruvada). - Clean up the AMD P-state driver documentation (Jan Engelhardt)" * tag 'pm-5.18-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (24 commits) Documentation: amd-pstate: grammar and sentence structure updates dt-bindings: cpufreq: cpufreq-qcom-hw: Convert to YAML bindings dt-bindings: dvfs: Use MediaTek CPUFREQ HW as an example Documentation: EM: Describe new registration method using DT OPP: Add support of "opp-microwatt" for EM registration PM: EM: add macro to set .active_power() callback conditionally OPP: Add "opp-microwatt" supporting code dt-bindings: opp: Add "opp-microwatt" entry in the OPP MAINTAINERS: Add additional file to uncore frequency control cpufreq: blocklist Qualcomm sc8280xp and sa8540p in cpufreq-dt-platdev cpufreq: qcom-hw: Add support for per-core-dcvs dt-bindings: power: avs: qcom,cpr: Convert to DT schema arm64: dts: qcom: qcs404: Rename CPU and CPR OPP tables arm64: dts: qcom: msm8996: Rename cluster OPP tables dt-bindings: opp: Convert qcom-nvmem-cpufreq to DT schema dt-bindings: opp: qcom-opp: Convert to DT schema arm64: dts: qcom: msm8996-mtp: Add msm8996 compatible dt-bindings: arm: qcom: Add msm8996 and apq8096 compatibles opp: Expose of-node's name in debugfs cpufreq: CPPC: Fix performance/frequency conversion ...
