Subject: [PATCH v19 2/6] dt-binding: i2c: mt65xx: add vbus-supply property
Date: Thu, 15 Apr 2021 01:29:12 +0800
Message-ID: <20210414172916.2689361-3-hsinyi@chromium.org> (raw)
In-Reply-To: <20210414172916.2689361-1-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.
