I think i have this already (pls see L231/L232 in https://pastebin.com/67wu9QrH )
I see you have hdmitxm1_cec as the enabled pin. Are you certain it's the m1 pin and not the m0 pin?
It depends on board ver. pls look: https://github.com/radxa/kernel/commit/c1d727692e85c0a265913a72e517cf2bd7113...
Maybe i miss something but adding:
&usb2phy0_otg { phy-supply = <&vcc5v0_usb_host>; status = "okay"; };
breaks working usb3 port0 (so none of usb3 ports are working)
Please pass along a full dmesg in this configuration.
