Subject: [PATCH v4 3/9] dt-bindings: input: touchscreen: add pressure threshold touchscreen property
Date: Mon, 30 Apr 2018 13:32:09 +0300 [thread overview]
Message-ID: <1525084335-11276-4-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1525084335-11276-1-git-send-email-eugen.hristev@microchip.com>
Add a common touchscreen optional property that will specify
the minimum pressure applied to the screen that is needed
such that the driver will report the touch event.
