Merge branch 'pm-devfreq'

Merge devfreq updates for 6.7-rc1:

 - Switch to dev_pm_opp_find_freq_(ceil/floor)_indexed() APIs to support
   specific devices like UFS which handle multiple clocks through OPP
   (Operationg Performance Point) framework (Manivannan Sadhasivam).

 - Add perf support to the Rockchip DFI (DDR Monitor Module) devfreq-
   event driver:
   * Generalize rockchip-dfi.c to support new RK3568/RK3588 using
     different DDR type (Sascha Hauer).
   * Convert devicetree bidning document format to yaml (Sascha Hauer).
   * Add perf support for DFI (a unit suitable for measuring DDR
     utilization) to rockchip-dfi.c to extend DFI usage (Sascha Hauer).

 - Add locking to the OPP handling code in the Mediatek CCI devfreq
   driver, because the voltage of shared OPP might be changed by
   multiple drivers (Mark Tseng, Dan Carpenter).

 - Use device_get_match_data() in the Samsung Exynos PPMU devfreq-event
   driver (Rob Herring).
