Subject: [PATCH v8 4/6] dt-bindings: usb: dwc3: Allow clock list & resets to be more flexible
Date: Tue, 25 Feb 2020 17:53:02 +0000	[thread overview]
Message-ID: <20200225175304.36406-5-john.stultz@linaro.org> (raw)
In-Reply-To: <20200225175304.36406-1-john.stultz@linaro.org>

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.
