The first generation i.MX6 processors does not send an interrupt when the power key is pressed. It sends a power down request interrupt if the key is released before a hard shutdown (5 second press). This should allow software to bring down the SoC safely. For this driver to work as a regular power key with the older SoCs, we need to send a keypress AND release when we get the power down request irq.

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.
