Markus Burri e71087ebcd Input: matrix_keypad - use fsleep for delays after activating columns
The delay is specified in a device property, so the duration can be
arbitrarily large. fsleep() determines the best way of delaying (sleep
vs spin) based on duration.

see Documentation/timers/delay_sleep_functions.rst

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 reStructuredText 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.
