Hi Michal,
I recently rebased my librem5 tree onto the latest u-boot-imx branch and the dwc3 host mode stopped working.
Further debugging indicates that the "U-Boot XHCI Host Controller" is detected but downstream USB 2 hubs and storage devices are not.
I bisected it down to this commit:
142d50fbce7c364a74f5e8204dba491b9f066e6c usb: dwc3: Add support for usb3-phy PHY configuration
Reverting that commit allows usb host mode to work on the librem5 again.
Should this initialization go into an SOC specific glue_configure function ?
Is the imx8mq.dtsi missing something that will keep usb host working with this patch ?
Does this break usb host on other imx8mq devices ?
Thanks Angus
