Missing CONFIG_ROCKCHIP_OPP in rk3308_linux_defconfig in branch linux-6.1-stan-rkr1 #295

Closed pavhofman closed 5 months ago

Missing CONFIG_ROCKCHIP_OPP=y in rk3308_linux_defconfig results in no compilation of rockchip_opp_select.c which results in cpufreq features not available, operating points defined in rk3308.dtsi ignored, and all cores running only at the initial 800MHz.

We do not support RK3308 on linux-6.1-stan-rkr1 branch right now. Currently we are using upstream kernel for RK3308 based devices.

I am afraid the upstream is broken in I2S - DMA integration https://forum.radxa.com/t/rock-pi-s-radxa-kernel-linux-6-1-stan-rkr1-inactive-usb-host/20552/4
