Fabio, Sorry for the confusion. This imx8mm dt sync patch will hang on imx8mm boards that use 'both' usbotg1 and usbotg2. You can reproduce this hang on your imx8mm-evk by enabling usbotg2 in the dt (the board has it but it is not enabled due to the gpio based usb 3.0 mux not being sorted out yet): +&usbotg2 { + dr_mode =3D "otg"; + status =3D "okay"; +}; + u-boot=3D> usb start && usb tree starting USB... Bus usb@32e40000: Bus usb@32e50000: ^^^ imx8mm-evk hangs This hang issue is not resolved by the regulator reference counter support and I am assuming that the power domain changes in this patch need to go along with a change in the power domain driver as well. I don't know yet if the imx8mn/imx8mp dt sync's in your series show issues during testing. Best Regards, Tim
