dt-bindings: devfreq: event: rockchip,dfi: Add rk3588 support (2023-10-19 21:27:11 +0900)
----------------------------------------------------------------
Update devfreq next for v6.7
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.
