This rewrites the IXP4xx watchdog driver as follows: - Spawn the watchdog driver as a platform device from the timer driver. It's one device in the hardware, and the fact that Linux splits the handling into two different devices is a Linux pecularity, and thus it becomes a Linux pecularity to spawn a separate watchdog driver. - Spawn the watchdog driver from the timer driver at probe(). This is well after the timer driver as actually registered and started and we know the register base is available. - Instead of looping back callbacks to the timer drivers for all watchdog calls, pass the register base to the watchdog driver and manage the registers there. The two drivers aren't even interested in the same register so the spinlock is totally surplus, delete it. - Replace pretty much all of the content in the watchdog driver with a simple, modern watchdog driver utilizing the watchdog core instead of registering its own misc device and ioctl() handling. - Drop module parameters as the same already exist in the watchdog core. What remains is a slim elegant (IMO) watchdog driver using the watchdog core, spawning from device tree or boardfile alike.

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.
