watchdog: i6300esb: use the watchdog subsystem
Radu Rendec authored

Change the i6300esb driver to use the watchdog subsystem instead of the
legacy watchdog API. This is mainly just getting rid of the "write" and
"ioctl" methods and part of the watchdog control logic (which are all
implemented by the watchdog subsystem).

Even though the watchdog subsystem supports registering and handling
multiple watchdog devices at the same time, the i6300esb driver still
has a limitation of only one i6300esb device due to some global variable
usage that comes from the original design. However, the driver can now
coexist with other watchdog devices (supported by different drivers).

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
