+Subject: [PATCH] BCM270X_DT: usb: Refactor DTS and overlays
+
+Move the IRQ interrupt declaration in the usb node before the FIQ
+declaration, so that the dwc2 driver will find it. Name the
+interrupts appropriately so that the dwc_otg driver can still find
+them. Then remove the interrupt rewriting from the overlays.
