Merge branch 'cpufreq/arm/linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm

Pull ARM cpufreq driver changes for v5.15 from Viresh Kumar:

"This contains:

 - Update cpufreq-dt blocklist with more platforms (Bjorn Andersson).

 - Allow freq changes from any CPU for qcom-hw driver (Taniya Das).

 - Add DSVS interrupt's support for qcom-hw driver (Thara Gopinath).

 - A new callback (->register_em()) to register EM at a more convenient
   point of time."
