If the first interrupt is the same on all devices, then this items 
list should be moved to the top level and just have a 'minItems: 4' 
here.

If the first interrupt is the same on all devices, then this items list
should be moved to the top level and just have a 'minItems: 4'
here.

From the hardware point, it is same "HSUSB interrupt"

But HW manual is  representing  it differently

R-Car Gen2, RZ/G1:-USB2.0_597 (OTG)
R-Car Gen3, RZ/G2:- EHCI/OHCI OTG.ch0
RZ/G2L: U2P_IXL_INT

Other devices ??.

So it make sense to leave as it is. Please let me know if you think other wise.

Regards,
Biju
