Subject: [PATCH 6/6] dt-bindings: usb: dwc3-imx8mp: add imx8mp dwc3 glue bindings
Date: Tue, 9 Jun 2020 19:12:45 +0800 [thread overview]
Message-ID: <1591701165-12872-7-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1591701165-12872-1-git-send-email-jun.li@nxp.com>
NXP imx8mp integrates 2 dwc3 3.30b IP and add some wakeup logic
to support low power mode, the glue layer is for this wakeup
functionality, which has a separated interrupt, can support
wakeup from U3 and connect events for host, and vbus wakeup for
device.
