Merge tag 'devfreq-next-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for v6.4 from Chanwoo Choi:

"1. Remove unneeded SRCU selection in Kconfig because it's always set from
    devfreq core.

 2. Fix minor updates of devfreq drivers
  - Drop of_match_ptr macro from exynos-bus.c because this driver is
    always using the DT table for driver probe.
  - Use the preferred of_property_present instead of the low-level
    of_get_property on exynos-bus.c
  - Use devm_platform_get_and_ioream_resource on exyno-ppmu.c"

* tag 'devfreq-next-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux:
  PM / devfreq: exynos-ppmu: Use devm_platform_get_and_ioremap_resource()
  PM / devfreq: exynos: Use of_property_present() for testing DT property presence
  PM / devfreq: exyos-bus: drop of_match_ptr for ID table
  PM / devfreq: Remove "select SRCU"
