Subject: [REPOST PATCH 2/3] Documentation: dt-bindings: Add snps,need-phy-for-wake for dwc2 USB
Date: Mon, 6 Jul 2015 11:27:03 -0700 [thread overview]
Message-ID: <1436207224-21849-3-git-send-email-dianders@chromium.org> (raw)
In-Reply-To: <1436207224-21849-1-git-send-email-dianders@chromium.org>
Some SoCs with a dwc2 USB controller may need to keep the PHY on to
support remote wakeup. Allow specifying this as a device tree
property.
