The code in serial.c looks up GPIOs corresponding to a line
on the UART when muxed in as GPIO to use this as a wakeup
on serial activity for OMAP1.
Utilize the NULL device to define some board-specific
GPIO lookups and use these to immediately look up the
same GPIOs, set as input and convert to IRQ numbers,
then set these to wakeup IRQs. This is ugly but should work.
This is only needed on the OSK1 and Nokia 770 devices that
use the OMAP16xx.

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.
