Subject: [PATCH v2 1/4] dt-bindings: usb: dwc2: Document quirk to reset PHY upon wakeup
Date: Tue, 16 Apr 2019 14:53:48 -0700 [thread overview]
Message-ID: <20190416215351.242246-2-dianders@chromium.org> (raw)
In-Reply-To: <20190416215351.242246-1-dianders@chromium.org>
On Rockchip rk3288 there's a hardware quirk where we need to assert
the reset signal to the PHY when we get a remote wakeup on one of the
two ports. Document this quirk in the bindings.
