Disable power down counter of the watchdog to avoid system resets. The
watchdog power down counter is set automatically by the chip. If it is

Improve power management operations(suspend and resume) as part of
dev_pm_ops for IMX2 watchdog driver.If PM will be supported, please make sure that the wdev->clk
could disable the watchdog's counter input clock source or can
mask watchdog's reset request to the core.If watchdog is still used by consumers and resumes from deep
sleep state, we need to restart the watchdog again without
enabling the timer.If watchdog been has started --> stopped by the consumers and
resumes from non-deep sleep state, then start the timer again.If watchdog has been started --> stopped by the consumers and
resumes from deep sleep state, will do nothing. The watchdog
will be restarted by consumers next time to be used.Signed-off-by: Xiubo Li

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.Everything has been in linux-next for a while"

Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann:
"On Atmel AT91, the conversion to device tree is now considered
complete, and all machines that were not already converted in 3.18 are
assumed to be unused and dropped by the maintainer.All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the
platform itself is not "multiplatform"-enabled, but both issues are
going to be taken care of in the 3.20 cycle.This is split out from the other cleanups purely based on the size of
the branch"* tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (33 commits)

The 25 MHz reference clock has better stability so its use is prefered over the
core clock. Change the Armada 375 clock initialization to use this reference
clock. To ensure the driver is compatible with an old devicetree, also provide
a fallback path which will silently return to the previous behavior.While here, add the clock specification to the binding documentation.

This patch adds support for the watchdog hardware found in A31 and
newer SoCs. This new hardware has registers at different offsets, and
the system reset control has been split out of the "mode" register
into a new "configuration" register.Differences not supported by this driver include separate interrupt
lines for each watchdog, instead of sharing an interrupt line and
registers with the timer block.Signed-off-by: Chen-Yu Tsai

This patch adds support for hardware parameters tied to compatible
strings, so similar hardware can reuse the driver.This will be used to support the newer watchdog found in A31 and
later SoCs. Differences in the new hardware include separate

The WDT's BITE_TIME warm-reset behavior can be leveraged as a last
resort mechanism for triggering chip reset. Usually, other restart
methods (such as PS_HOLD) are preferrable for issuing a more complete

low.Signed-off-by: Josh Cartwright
