[WATCHDOG] w83977f-watchdog-driver.patch

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON.  The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.

I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.

+          This is the driver for the hardware watchdog on the W83977F I/O chip
+          as used in AAEON's PCM-5335 SBC (and likely others).  This
+          watchdog simply watches your kernel to make sure it doesn't freeze,
+          and if it does, it reboots your computer after a certain amount of
+          time.

+          To compile this driver as a module, choose M here: the
+          module will be called w83977f_wdt.
