[PATCH v7 4/8] dt-bindings: usb: dwc3: Allow clock list & resets to be more flexible

From: John Stultz
Date: Wed Dec 11 2019 - 20:42:47 EST


Rather then adding another device specific binding to support
hikey960, Rob Herring suggested we expand the current dwc3
binding to allow for variable numbers of clocks and resets.
