+From a2073bd47b86b1ad3ba0600e772cd0f14ba73838 Mon Sep 17 00:00:00 2001
+From: Linus Walleij <linus.walleij@linaro.org>
+Date: Fri, 31 Jan 2014 14:34:35 +0100
+Subject: [PATCH 1/7] MFD: driver for Atmel Microcontroller on iPaq h3xxx
+
+This adds a driver for the Atmel Microcontroller found on the
+iPAQ h3xxx series. This device handles some keys, the
+touchscreen, and the battery monitoring.
+
+This is a port of a driver from handhelds.org 2.6.21 kernel,
+written by Alessandro Gardich based on Andrew Christians
+original HAL-driver. It has been heavily cleaned and
+converted to mfd-core by Dmitry Artamonow and rewritten
+again for the v3.x series kernels by Linus Walleij,
+bringing back some of the functionality lost from Andrew's
+original driver.
