Merge tag 'cpufreq-arm-updates-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm

Pull cpufreq ARM updates for 6.2 from Viresh Kumar:

"- Generalize of_perf_domain_get_sharing_cpumask phandle format (Hector
   Martin).

 - New cpufreq driver for Apple SoC CPU P-states (Hector Martin).

 - Lots of Qualcomm cpufreq driver updates, that include CPU clock
   provider support, generic cleanups or reorganization, fixed a
   potential memleak and the return value of cpufreq_driver->get()
   (Manivannan Sadhasivam, and Chen Hui).

 - Few updates to Qualcomm cpufreq driver's DT bindings, that include
   support for CPU clock provider, fixing missing cache related
   properties, and support for QDU1000/QRU1000 (Manivannan Sadhasivam,
   Rob Herring, and Melody Olvera).

 - Add support for ti,am625 SoC and enable build of ti-cpufreq for
   ARCH_K3 (Dave Gerlach, and Vibhore Vardhan).

 - tegra186: Use flexible array to simplify memory allocation (Christophe
   JAILLET)."
