-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.
