Sascha, Michael,

I'm using v11 series on 5.18-rc5 on rk3566 tvbox with great success.
Recently i started to work on rock3-a (rk3568).
v11 gives me video, audio - but cec is not working on rock3-a.

I was told:

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

I was trying to do this in dts https://pastebin.com/67wu9QrH but cec is still 
non-functional

Maybe You have some hints/pointers here?

br

btw: my dts gives me working usb2 port0/port1 and usb3 port0. but usb3 port1 is 
non-working
maybe you know what is missing?
