Subject: [PATCH 4/4] ARM: dts: rockchip: Add quirk for resetting rk3288's dwc2 host on wakeup
Date: Fri, 12 Apr 2019 15:41:49 -0700 [thread overview]
Message-ID: <20190412224149.106971-5-dianders@chromium.org> (raw)
In-Reply-To: <20190412224149.106971-1-dianders@chromium.org>
The "host" USB port on rk3288 has a hardware errata where we've got to
assert a PHY reset whenever we see a remote wakeup. Add that quirk
property to the device tree.
