2012-05-22drivers:watchdog:ux500: Disable when timeout == 0Per Fransson
Setting the watchdog timeout to 0 makes any attempt to open the dev node fail. This makes it possible to disable the watchdog functionality on the kernel commandline with "ux500_wdt.timeout=0", ST-Ericsson ID: 365851 ST-Ericsson Linux next:NA ST-Ericsson FOSS-OUT ID:Trivial Change-Id: I917258c9310ea2267c877c3c13d00dc08c30a147 Signed-off-by: Per Fransson <per.xx.fransson@stericsson.com> Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/45299 Reviewed-by: QATOOLS Reviewed-by: QABUILD Reviewed-by: Srinidhi KASAGAR <srinidhi.kasagar@stericsson.com>

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

2012-03-27watchdog: watchdog_dev: Let the driver update the timeout field on ↵Hans de Goede
set_timeout success When a set_timeout operation succeeds this does not necessarily mean that the exact timeout requested has been achieved, because the watchdog does not necessarily have a 1 second resolution. So rather then have the core set the timeout member of the watchdog_device struct to the exact requested value, instead the driver should set it to the actually achieved timeout value.

2012-03-27watchdog: pnx4008: cleanup resource handling using managed devicesWolfram Sang
The resource handling in this driver was flaky: IO_ADDRESS instead of ioremap (and no unmapping), an unneeded static resource, no central exit path for error cases. Fix this by converting the driver to use managed resources. Also use dev_*-messages instead of pr_* while we are here.
