Subject: [PATCH v4 4/9] dt-bindings: usb: dwc3: Allow clock list & resets to be more flexible
Date: Mon, 28 Oct 2019 21:59:14 +0000	[thread overview]
Message-ID: <20191028215919.83697-5-john.stultz@linaro.org> (raw)
In-Reply-To: <20191028215919.83697-1-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.
