+
+Interrupts for DWC3 node were completely mixed up - SPI interrupt 62 is
+not listed in reference manual at all. It was also causing dtbs_check
+warnings:
+
+ ipq5018-rdp432-c2.dtb: usb@8af8800 (qcom,ipq5018-dwc3): interrupt-names:0: 'pwr_event' was expected
+ ipq5018-rdp432-c2.dtb: usb@8af8800 (qcom,ipq5018-dwc3): interrupt-names: ['hs_phy_irq'] is too short
+
+Warning itself was introduced by commit 53c6d854be4e ("dt-bindings: usb:
+dwc3: Clean up hs_phy_irq in binding"), but this was trying to bring
+sanity to the interrupts overall, although did a mistake for IPQ5018.
+IPQ5018 does not have QUSB2 PHY and its interrupts should rather match
+ones used in IPQ5332.
+
+Correct it by using interrupts matching the bindings and reference
+manual.
