Merge tag 'devfreq-next-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Merge devfreq updates for v6.7 from Chanwoo Choi:

" Detailed description for this pull request:
 1. Update devfreq core
 - Switch to dev_pm_opp_find_freq_(ceil/floor)_indexed() APIs
   to support the specific device like UFS which handle the multiple clocks
   through OPP (Operationg Performance Point) framework.

 2. Update the devfreq / devfreq-event drivers
 - 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.
 : Covert devicetree bidning document format to yaml.
 : DFI is a unit which is suitable for measuring DDR utilization
   for the DDR frequency scaling driver. Add perf support feature
   to rockchip-dfi.c to extend DFI usage. The perf support has been tested
   on a RK3568 and a RK3399.

 - Protect the OPP handling code in critical section
   because the voltage of shared OPP might be changed by multiple drivers
   on Mediatek CCI devfreq driver.

 - Use device_get_match_data() on Samsung Exynos PPMU devfreq-event driver."
