Subject: [PATCH] arm64: dts: rockchip: fix RK3576 CPU OPP voltages for cpufreq
Fix severe CPU performance issues on RK3576 mainline kernel 6.16 caused
by incorrect OPP voltage values. Current values are too conservative,
preventing proper cpufreq scaling and causing suboptimal performance.
Update voltage tables for both CPU clusters based on Rockchip vendor BSP:
- Increase base voltage from 700mV to 712.5mV for stability
- Adjust high-frequency OPP voltages for proper scaling
- Add intermediate frequency points (1920MHz cluster0, 2112MHz cluster1)
- Remove unstable frequency points
This enables proper CPU frequency scaling and significantly improves
system performance.
