2017-02-24watchdog: constify watchdog_ops structuresBhumika Goyal
Declare watchdog_ops structures as const as they are only stored in the ops field of a watchdog_device structure. This field is of type const, so watchdog_ops structures having this property can be made const too. Done using Coccinelle: @r disable optional_qualifier@ identifier x; position p; @@ static struct watchdog_ops x@p={...}; @ok@ struct watchdog_device w; identifier r.x; position p; @@ w.ops=&x@p; @bad@ position p != {r.p,ok.p}; identifier r.x; @@ x@p @depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct watchdog_ops x; File size details before and after patching.

2015-09-09Watchdog: Fix parent of watchdog_devicesPratyush Anand
/sys/class/watchdog/watchdogn/device/modalias can help to identify the driver/module for a given watchdog node. However, many wdt devices do not set their parent and so, we do not see an entry for device in sysfs for such devices. This patch fixes parent of watchdog_device so that /sys/class/watchdog/watchdogn/device is populated. Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not have any parent. Not sure, how we can identify driver for these devices.

2013-11-17watchdog: sirf: don't depend on dummy value of CLOCK_TICK_RATEUwe Kleine-König
As CSR SiRF is converted to multi platform CLOCK_TICK_RATE is a dummy value that seems to match the right value is used. (arch/arm/mach-prima2/include/mach/timex.h which defined CLOCK_TICK_RATE to 1000000 was removed in commit cf82e0e (ARM: sirf: enable multiplatform support); marco used the same file.) To not depend on that dummy value use a local #define instead. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2013-11-17watchdog: sirf: add watchdog driver of CSR SiRFprimaII and SiRFatlasVIXianglong Du
On CSR SiRFprimaII and SiRFatlasVI, the 6th timer can act as a watchdog timer when the Watchdog mode is enabled. watchdog occur when TIMER watchdog counter matches the value software pre-set, when this event occurs, the effect is the same as the system software reset.
