Merge tag 'pm-6.13-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These mostly are updates of cpufreq drivers used on ARM platforms plus
  one new DT-based cpufreq driver for virtualized guests and two cpuidle
  changes that should not make any difference on systems currently in
  the field, but will be needed for future development:

   - Add virtual cpufreq driver for guest kernels (David Dai)

   - Minor cleanup to various cpufreq drivers (Andy Shevchenko, Dhruva
     Gole, Jie Zhan, Jinjie Ruan, Shuosheng Huang, Sibi Sankar, and Yuan
     Can)

   - Revert "cpufreq: brcmstb-avs-cpufreq: Fix initial command check"
     (Colin Ian King)

   - Improve DT bindings for qcom-hw driver (Dmitry Baryshkov, Konrad
     Dybcio, and Nikunj Kela)

   - Make cpuidle_play_dead() try all idle states with :enter_dead()
     callbacks and change their return type to void (Rafael Wysocki)"

+description:
+  Virtual CPUFreq is a virtualized driver in guest kernels that sends performance
+  selection of its vCPUs as a hint to the host through MMIO regions. Each vCPU
+  is associated with a performance domain which can be shared with other vCPUs.
+  Each performance domain has its own set of registers for performance controls.
+
+properties:
+  compatible:
+    const: qemu,virtual-cpufreq

+  reg:
+    maxItems: 1
+    description:
+      Address and size of region containing performance controls for each of the
+      performance domains. Regions for each performance domain is placed
+      contiguously and contain registers for controlling DVFS(Dynamic Frequency
+      and Voltage) characteristics. The size of the region is proportional to
+      total number of performance domains.
