Subject: [PATCH v4 2/3] ARM: dts: Add Peach Pi dts entry for Atmel touchpad
Date: Wed, 10 Sep 2014 13:31:30 +0200	[thread overview]
Message-ID: <1410348691-18317-3-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1410348691-18317-1-git-send-email-javier.martinez@collabora.co.uk>

The Peach Pi board has an Atmel maXTouch trackpad device.
Add the needed Device Tree nodes to support it.

This Device Tree change is based on the Chrome OS 3.8 tree
but adapted to use the mainline Atmel maXTouch DT binding.

Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk>

Changes since v3: None, new patch.
