How to enable USB OTG for LS1046A

Hello,

We are currently try to use the #OTG feature for USB on the LS1046A. We have added:

- CONFIG_USB_DWC3_DUAL_ROLE=y

- CONFIG_USB_OTG=y

to the kernel defconfig and changed the dr_mode in the device tree to "otg".

When using the USB in "peripheral" mode the USB is working as a mass storage device as expected. but when using "otg" the USB port is not working as host or device.

What steps are needed to enable the OTG? What did we forget or did wrong?

Thanks!

Regards,

Andreas
