* watchdog: Use "request_muxed_region" in it87 watchdog driversNat Gurumoorthy2011-07-221-78/+90
| | | | | | | | | | | | | | | | | | | Changes the it87 watchdog drivers to use "request_muxed_region". Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. The use of the above macro makes it possible to get rid of spinlocks in it8712f_wdt.c and it87_wdt.c watchdog drivers. This also greatly simplifies the implementation of it87_wdt.c driver. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

| | | | | | | | | | | | | | This patch adds support for a watchdog in IT8721F Super IO chip to it87_wdt driver. This new chips differ from the older IT87xxxF chips in the following ways: * WDT_GAMEPORT is not in IT8721F. * WDT_PWROK is not in IT8721F.
