From: qianfan Zhao <qianfanguijin@xxxxxxx> Change history: =============== v5(2022-05-17): - Move opp tables to sun8i-r40-cpu-opp.dtsi - cpufreq supports 720M, 912M, 1G, 1.1G, 1.2G - Add cooling supports v4(2022-05-16): - Invert two patches. - Drop the cpufreqs that exceeds 1G in opp tables. v3: - remove "allwinner-r40" compatible from allowlist. - split dts in two part. Test: ===== cpufreq was tested by tools: https://github.com/ssvb/cpuburn-arm 1. cpufreq-ljt-stress-test - root@ubuntu:~/cpuburn-arm-master# ./cpufreq-ljt-stress-test - CPU stress test, which is doing JPEG decoding by libjpeg-turbo - at different cpufreq operating points. - - Testing CPU 0 - 1200 MHz ............................................................
