* watchdog: nowayout is boolWim Van Sebroeck2012-03-271-2/+2
| | | | | | | nowayout is actually a boolean value. So make it bool for all watchdog device drivers. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: Use pr_<fmt> and pr_<level>Joe Perches2012-03-271-5/+7
| | | | | | | | | | | | 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>
* watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREADVenkat Subbiah2011-11-051-1/+1
| | | | | | | | | | | | | | | | This is to exclude it from force threading to allow RT patch set to work. The watchdog timers are per-CPU and the addresses of register that reset the timer are calculated based on the current CPU. Therefore we cannot allow it to run on a thread on a different CPU. Also we only do a single register write, which is much faster than scheduling a handler thread. And while on this line remove IRQF_DISABLED as this flag is a NOP.

* WATCHDOG: octeon-wdt: Use I/O clock rate for timing calculations.David Daney2010-10-291-2/+2
| | | | | | | | | | | | | The creation of the I/O clock domain requires some adjustments. Since the watchdog counters are clocked by the I/O clock, use its rate for timing calculations.

* MIPS: Add missing #inclusions of <linux/irq.h>David Howells2010-10-071-0/+1
| | | | | | | | | | | | | | Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should really include it. Note that this can replace #inclusions of <asm/irq.h>. This is required for the patch to sort out irqflags handling function naming to compile on MIPS. The problem is that these files require access to things like setup_irq() - which isn't available by #including <linux/interrupt.h> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Ralf Baechle <ralf@linux-mips.org>
* WATCHDOG: Add watchdog driver for OCTEON SOCsDavid Daney2010-08-051-0/+745
The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit. The driver is split into two source files one for the C code and one for assembly. Assembly is needed to handle the NMI and then print the machine state before the reboot is triggered.
