[PATCH] usb: dwc3: imx8mp: detect dwc3 child nodes with name "usb*"

[PATCH] usb: dwc3: imx8mp: detect dwc3 child nodes with name "usb*"

[Heiko Schocher]

commit:
d1689cd3c0f4: ("arm64: dts: imx8mp: Use the correct name for child node "snps, dwc3")

renamed "dwc3@3*" nodes in imx8mp.dtsi to "usb@3*"

glue layer dwc3-imx8mp.c searches for "dwc3" and so drop failure
on boot:
imx8mp-dwc3 32f10100.usb: failed to find dwc3 core child
imx8mp-dwc3: probe of 32f10100.usb failed with error 1
imx8mp-dwc3 32f10108.usb: failed to find dwc3 core child
imx8mp-dwc3: probe of 32f10108.usb failed with error 1

now. Fix this (and allow old style too)

Tested on "PHYTEC phyBOARD-Pollux i.MX8MP" board.

fixes: d1689cd3c0f4: ("arm64: dts: imx8mp: Use the correct name for child node "snps, dwc3")
