[PATCH 1/7] dt-bindings: usb: qcom,dwc3: add SC8280XP binding

From: Johan Hovold
Date: Wed Jul 13 2022 - 09:18:12 EST


Add SC8280XP to the DT schema.

Note that the SC8280XP controllers use the common set of five clocks and
an additional set of four interconnect clocks whose purpose is not
entirely clear at this point.

The set of wakeup interrupts is also different for SC8280XP.
