[PATCH 00/12] watchdog: sp5100_tco: Various improvements

[Guenter Roeck]

The sp5100_tco watchdog driver does not really support recent AMD CPUs,
even though it claims to do so. On top of that, it doesn't use the
watchdog subsystem, and various other problems have crept in. Let's
clean it up for good.

The code was tested on AMD Ryzen 1700 with motherboards from MSI and
Gigabyte. Tests on older hardware would be useful to make sure that
nothing broke.
