From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ahmet Inan Subject: [PATCH 2/2] dt-bindings: Add I2C attached EETI EXC3000 bindings Date: Fri, 6 Oct 2017 09:37:28 +0200 Message-ID: <20171006073728.14724-2-inan@distec.de> References: <20171006073728.14724-1-inan@distec.de> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <20171006073728.14724-1-inan@distec.de> Sender: linux-input-owner@vger.kernel.org To: Dmitry Torokhov Cc: Ahmet Inan , linux-input@vger.kernel.org, Rob Herring , devicetree@vger.kernel.org, Ahmet Inan List-Id: devicetree@vger.kernel.org This documents the use of the dt-bindings for the EETI EXC3000 driver with the following example configuration: Using the I2C address 0x2a of the touch controller in the driver. Using pin 9 as low level-sensitive interrupt to signal the driver. Using a 4096x4096 touch screen resolution. Inverting the x-axis and swapping the result with the y-axis.
