This adds the code for the Atmel touchscreens such as mXT224 to obtain power regulators for the supply voltages AVDD and VDD. On mobile phones such as Samsung GT-I8190 (Golden) this is needed to explicitly bring power online. We just enable the regulators at probe() and disable them at remove() or in the error path for now. As regulators are naturally stubbed if not available, this should have no impact on existing systems.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
