Subject: [PATCH 1/2] dt-bindings: usb: mediatek,mtk-xhci: add keep-clock-on
Date: Mon, 2 Nov 2020 15:18:48 +0800	[thread overview]
Message-ID: <1604301530-31546-1-git-send-email-macpaul.lin@mediatek.com> (raw)

Option "mediatek,keep-clock-on" means to keep clock on during system
suspend and resume. Some platform will flush register settings if clock has
been disabled when system is suspended. Set this option to avoid clock off.
