Subject: [PATCH 6/6] doc: dt-binding: cdns,usb3: add wakeup-irq
Date: Thu, 22 Oct 2020 09:44:11 +0800 [thread overview]
Message-ID: <20201022014411.2343-1-peter.chen@nxp.com> (raw)
To support low power mode for controller, the driver needs wakeup-irq
to reflect the signal changing after controller is stopped, and waking
the controller up accordingly.
