Subject: [PATCH v20 2/5] dt-binding: i2c: mt65xx: add vbus-supply property
Date: Tue, 27 Apr 2021 13:36:14 +0800 [thread overview]
Message-ID: <20210427053617.27972-3-hsinyi@chromium.org> (raw)
In-Reply-To: <20210427053617.27972-1-hsinyi@chromium.org>
Add vbus-supply property for mt65xx. The regulator can be passed into
core and turned off during suspend/sleep to reduce power consumption.
