Subject: [PATCH v4 1/4] dt-bindings: input: touchscreen: goodix: Document AVDD28-supply property
Date: Tue, 12 Feb 2019 16:54:36 +0530 [thread overview]
Message-ID: <20190212112439.2025-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190212112439.2025-1-jagan@amarulasolutions.com>
Most of the Goodix CTP controllers are supply with AVDD28 pin.
which need to supply for controllers like GT5663 on some boards
to trigger the power.
So, document the supply property so-that the require boards
that used on GT5663 can enable it via device tree.
