From bf8f0392306869412887bf4a681fea9cb8062fc5 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 2 Sep 2014 09:57:09 -0600 Subject: [PATCH] ARM: tegra: add touchpad to Venice2 DT Venice2 contains an Atmel MXT touchpad. Add an I2C node for it to DT. The Linux driver doesn't quite work on this platform yet, but adding the DT node causes no issues, and will allow the device to work once the driver is fixed.
