[PATCH] watchdog: it87_wdt: Add support for IT8728F watchdog.

From: Diego Elio PettenÃ
Date: Wed Mar 14 2012 - 15:52:53 EST


This works the same way IT8721F works, but it supports WDT_PWROK
(checked on the datasheet).

This is the driver for the hardware watchdog on the ITE IT8702,
- IT8712, IT8716, IT8718, IT8720, IT8721, IT8726 Super I/O chips.

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.
