Marek Vasut 6bd39dee63 ARM: dts: imx: Switch USB1 port control to GPIO on Data Modul i.MX8M Plus eDM SBC
The USB_PWR signal operation is not reliable on this DWC3 controller
instance in case the signal is active high. Switch to GPIO control,
which always behaves correctly. Perform the change in u-boot extras
until this hits Linux upstream.
