Subject: [PATCH v11 4/7] dt-bindings: sun6i-dsi: Add VCC-DSI supply property
Date: Thu, 3 Oct 2019 12:15:24 +0530 [thread overview]
Message-ID: <20191003064527.15128-5-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191003064527.15128-1-jagan@amarulasolutions.com>
Allwinner MIPI DSI controllers are supplied with SoC DSI
power rails via VCC-DSI pin.
Some board still work without supplying this but give more
faith on datasheet and hardware schematics and document this
supply property in required property list.
