How to interface USB HSIC on iMX8QM in devicetree?

Hello

On L4.14 releases there has always been a device-tree-node called &usbh1 (@ 0x5b0e0000) with that we were able to interface the USB HSIC interface to our USB Hub.

In the latest L5.4.24-2.1.0 release there is no such interface anymore. I searched with the address (0x5b0e0000) if it is newly named but was not successful. This interface seems to be completely gone.

I then tried to bring up the usb interface with fsl,imx7ulp-usb compatible but without success. It always crashed when trying to load so I gave up.

Our original question from 2.5 years ago was here: USB HSIC support for iMX8QM

This issue seems to be tracked in your internal system as: MLK-16715

Could you please send us a patch where you add support back for interface 0x5b0e0000 on iMX8QM (pads USB_HSIC0_STROBE and USB_HSIC0_DATA)

Thanks in advance,
Philippe Schenker
