Hi Michal,

Thank you for the patch.

Based on DT binding dwc_usb3 is single entry without anything else. That's
why combination dwc3_usb3, otg is not allowed. That's why split it to host
and peripheral pair which both points to the same IRQ.
DWC3 code is reading these two properties first before generic dwc_usb3.

This should read

interrupts = <GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;

The issue isn't introduced by this patch, so it should probably be fixed
by a separate patch on top, to convert the whole zynqmp.dtsi file. Do
you have any plan to do so, or should I ?

I have sent it here.

Feel free to review it.

Thanks,
