For instance how > come you are modifying the power domains? This was experiment as I was advised: "32k clock needed for cec and this clock is generated by the rtc which is embedded in the rk8xx regulator. So you should make sure it is enabled when hdmi is powerd on, eg adding it to the RK3568_PD_VO powerdomain should help" power domains entries in dts was attempt to play with above cec clock sugestion. M0/M1 logs in this email are from cleaned dts: https://pastebin.com/0pgwpdsS > USB3 is broken because the rock3-a is a rk3568 device and you're > missing combophy0. Perfect. all 4 usb ports are now working. Also no errors in dmesg. Thx!
