2012-11-28watchdog: remove use of __devexitBill Pemberton
CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed.

2012-07-23watchdog: sch311x_wdt: Fix Polarity when starting watchdogWim Van Sebroeck
Some motherboards like the Advantech ARK3400 documentation use a non-inverted GPIO pin. We fix this by assuming that the BIOS will set the Polarity bit for the GPIO correctly at startup and we keep the Bit-setting intact when we start and stop the watchdog.

2012-05-23watchdog: sch311x_wdt.c: Remove RESGENDave Mueller
The SCH311x chip contains 2 watchdogs. One is the watchdog programmable by the runtime register at address 0x65-0x68, the other is the watchdog inside the power on reset generator. This second watchdog has a fixed timeout value of ~1.6 seconds and is configurable only by the RESGEN register. The BIOS normally takes care of the RESGEN watchdog and disables it (at least) before the OS is booted. Unfortunately the sch311x_wdt driver clears bit 0 of the RESGEN register which has the effect that at the latest 1.6 seconds later, a POR is triggered. The attached patch fixes this problem by completely removing any reference to the RESGEN watchdog from the sch311x_wdt driver.

nowayout is actually a boolean value. So make it bool for all watchdog device drivers. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

Use the current logging styles. Make sure all output has a prefix. Add missing newlines. Remove now unnecessary PFX, NAME, and miscellaneous other #defines. Coalesce formats. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2011-07-26watchdog: remove empty pm-functionsWolfram Sang
While checking what watchdog drivers usually do in suspend/resume to spot common behaviour for the watchdog framework, I found these drivers which do nothing but add some cruft. Remove it, it is superfluous. New approaches should probably be done with pm_ops anyway. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
