The SoQuartz CM4-IO should support otg mode, however it currently
defaults to device mode when otg is enabled. Force it to host mode to
retain the previous behavior.

Fixes: bc405bb3eeee ("arm64: dts: rockchip: enable otg/drd operation of usb_host0_xhci in rk356x")

It would seem the role-switch issue is more widespread than originally
thought, affecting other boards where automatic control should work.
Please hold this patch while I investigate further.

Thanks!

ok!

I guess this also applies to

No, on Quartz64 Model A it can't work, the requisite pin isn't connected.
I think I've found the problem, I've requested a few people to test a fix.
Do you have a Model B or SoQuartz to test against (or any other rk356x
board that has the id pin hooked up)?

Thanks,
Peter

No, on Quartz64 Model A it can't work, the requisite pin isn't connected.
I think I've found the problem, I've requested a few people to test a fix.
Do you have a Model B or SoQuartz to test against (or any other rk356x
board that has the id pin hooked up)?

Thanks,
Peter

The rk356x in my boardfarm is a Quartz-B ... though an very early model,
so hopefully nothing changed on the board since then.

Although there is nothing connected to usb right now and I only have
remote access this weekend, so any usb tests would need to wait till next
week on my end.
