Subject: [PATCH v2 2/5] dt-bindings: usb: mtk-xhci: add wakeup interrupt
Date: Sat, 10 Apr 2021 13:10:03 +0800 [thread overview]
Message-ID: <1618031406-15347-2-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1618031406-15347-1-git-send-email-chunfeng.yun@mediatek.com>
Add an interrupt which is EINT usually to support runtime PM,
meanwhile add "interrupt-names" property, for backward
compatibility, it's optional and used when wakeup interrupt
exists
