2012-05-23watchdog: sch311x_wdt.c: Remove RESGENDave Mueller1-34/+5
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>
2012-03-27watchdog: Use pr_<fmt> and pr_<level>Joe Perches1-7/+6
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>
2011-07-27watchdog: remove empty pm-functionsWolfram Sang1-5/+0
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>

"==" has higher precedence than "&". Since if (sch311x_sio_inb(sio_config_port, 0x30) & (0x01 == 0)) is always false the message is never printed. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
