Subject: [PATCH RESEND v3 1/2] dt-bindings: input: atmel,maxtouch: add poweroff-sleep property
Date: Fri,  9 Feb 2024 11:50:11 +0100	[thread overview]
Message-ID: <20240209105012.22470-2-eichest@gmail.com> (raw)
In-Reply-To: <20240209105012.22470-1-eichest@gmail.com>

From: Stefan Eichenberger <stefan.eichenberger@toradex.com>

Add a new property to indicate that the device should power off rather
than use deep sleep. Deep sleep is a feature of the controller that
expects the controller to remain powered in suspend. However, if a
display shares its regulator with the touch controller, we may want to
do a power off so that the display and touch controller do not use any
power.
