From what I see in the other thread, the USB never worked with the
series. If the controller returns 0s as EHCI version, something is obviously broken and I don't even understand how that could be an acceptable positive test result. The USB HCD version register can NOT EVER contain zeroes as per the specification. I am really unhappy here.
This is untrue, the controller returns 0's only when single node enabled not with both ehci0 and echi1 atleast on BPI-M64. and we do enable both controller on dts even with other boards too. having single node enablement is not a proper test or not with my dts atleast.
Clock for EHCI0 or OHCI0 was never enabled on your series, so reading USB HCD version for EHCI0/OHCI0 always returned 0 and you should have seen 0.0 as version for EHCI0 and OHCI0.
With both nodes enabled you had only EHCI1/OHCI1 functional.
