2016-03-01watchdog: Add 'action' and 'data' parameters to restart handler callbackGuenter Roeck1-1/+2
The 'action' (or restart mode) and data parameters may be used by restart handlers, so they should be passed to the restart callback functions. Cc: Sylvain Lemieux <slemieux@tycoint.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2015-09-09Watchdog: Fix parent of watchdog_devicesPratyush Anand1-0/+1
/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.

2014-03-31watchdog: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-03-01watchdog: bcm47xx_wdt.c: add hard timerHauke Mehrtens1-6/+63
The more recent devices have a watchdog timer which could be configured for over 2 hours and not just 2 seconds like the first generation devices. For those devices do not use the extra software timer, but directly program the time into the register. This will automatically be used if the timer supports more than a minute.

Prepare bcm47xx to support different System buses. Before adding support for bcma it should be possible to build bcm47xx without the need of ssb. With this patch bcm47xx does not directly contain a ssb_bus, but a union contain all the supported system buses. As a SoC just uses one system bus a union is a good choice.

2009-06-20[WATCHDOG] add bcm47xx watchdog drivermatthieu castet1-0/+286
This add watchdog driver for broadcom 47xx device. It uses the ssb subsytem to access embeded watchdog device. Because the watchdog timeout is very short (about 2s), a soft timer is used to increase the watchdog period. Note : A patch for exporting the ssb_watchdog_timer_set will be submitted on next linux-mips merge. Without this patch it can't be build as a module.
