rtc: ds1374: wdt: Fix stop/start ioctl always returning -EINVAL

2018-05-23T01:33:51Z

[ Upstream commit 538c08f4c89580fc644e2bc64e0a4b86c925da4e ] The WDIOC_SETOPTIONS case in the watchdog ioctl would alwayss falls through to the -EINVAL case. This is wrong since thew watchdog does actually get stopped or started correctly.

rtc: ds1374: wdt: Fix issue with timeout scaling from secs to wdt ticks

2018-05-23T01:33:51Z

[ Upstream commit 453d0744f6c6ca3f9749b8c57c2e85b5b9f52514 ] The issue is that the internal counter that triggers the watchdog reset is actually running at 4096 Hz instead of 1Hz, therefore the value given by userland (in sec) needs to be multiplied by 4096 to get the correct behavior.

drivers/rtc/rtc-ds1374.c: add watchdog support

2014-12-11T01:41:15Z

Add support for the watchdog functionality of the DS1374 rtc. Based on the m41t80 watchdog functionality Note: watchdog uses the same registers as alarm.

devm_* functions are device managed and make cleanup code simpler. Signed-off-by: Sachin Kamat Cc: Scott Wood Cc: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-ds1374.c: add CONFIG_PM_SLEEP to suspend/resume functions

2013-04-30T01:28:33Z

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/rtc/rtc-ds1374.c:413:12: warning: 'ds1374_suspend' defined but not used [-Wunused-function] drivers/rtc/rtc-ds1374.c:422:12: warning: 'ds1374_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
