in chipidea-imx.c there is :

	mode =3D of_usb_get_dr_mode(ci->dev->device_node, NULL);

	switch (mode) {
	case USB_DR_MODE_HOST:
	default:
		ci->mode =3D IMX_USB_MODE_HOST;
		break;
	case USB_DR_MODE_PERIPHERAL:
		ci->mode =3D IMX_USB_MODE_DEVICE;
		break;
	}

so we could omit the dr_mode=3Dhost as it will default to host.

Eric
