Daniel Mack b283d0c353 Input: eeti_ts - read hardware state once after wakeup
For systems in which the touch IRQ is acting as wakeup source, and that do
not support level-driven interrupts, the interrupt controller might not
latch the GPIO IRQ during sleep. In such cases, the interrupt will never
occur again after resume, hence the touch screen appears dead.

To fix this, check for the assertion of the attn gpio, and read form the
controller once in the resume path to read the hardware status and
to arm the IRQ again.

Introduce a mutex to guard eeti_ts_read() against parallel invocations
from different contexts.

README

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.
