Subject: [PATCH v5 1/4] dt-bindings: input: touchscreen: goodix: Document regulator properties
Date: Sun, 17 Feb 2019 14:44:33 +0530 [thread overview]
Message-ID: <20190217091436.3702-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190217091436.3702-1-jagan@amarulasolutions.com>
Goodix CTP controllers support analog, digital and gpio regulator
supplies on relevant controller pin configurations.
Out of which AVDD28 regulator is mandatory supplied regulator in most
of the board designs, so document AVDD28 as required property and
rest marked as optional regulators.
