All three iop variants we support in Linux (iop32x, iop33x and
iop13xx) seem to have support for the watchdog hardware, but this
driver fails to build for the first two of these because it
uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for
iop13xx.
This clarifies the dependency in Kconfig to avoid randconfig
build errors. It is unlikely that anyone will ever miss support
for this driver on the ancient iop3xx platforms, so we don't
need to bother trying to fix it properly.

The watchdog_init_timeout() can read timeout value from timeout-sec
property if the passed value is out of bounds. The heartbeat is
initialized in next way. If heartbeat is not set thought module
parameter, try to read it's value from WDT node timeout-sec property.
If node has no one, use default value.
The heartbeat is hold in wdd->timeout by WDT core, so use it in

found on MOXA ART SoCs.
The MOXA ART SoC provides one writable timer register, restarting
the hardware once it reaches zero. The register is auto decremented
every APB clock cycle.

This patch adds the driver for the watchdog found in the Allwinner A10 and
A13 SoCs. It has DT-support and uses the new watchdog framework.

Pull MIPS updates from Ralf Baechle:
"MIPS updates:
- All the things that didn't make 3.10.
- Removes the Windriver PPMC platform. Nobody will miss it.
- Remove a workaround from kernel/irq/irqdomain.c which was there
exclusivly for MIPS. Patch by Grant Likely.
- More small improvments for the SEAD 3 platform
- Improvments on the BMIPS / SMP support for the BCM63xx series.
- Various cleanups of dead leftovers.
- Platform support for the Cavium Octeon-based EdgeRouter Lite.
Two large KVM patchsets didn't make it for this pull request because
their respective authors are vacationing"

This patch adds the driver for the watchdog devices found on MEN Mikro
Elektronik A21 VMEbus CPU Carrier Boards. It has DT-support and uses the
watchdog framework.

The watchdog infrastructure in Dove is no different from that in
Orion5x or Kirkwood, so let's enable it for Dove. The only things
missing are a few register settings in Dove's bridge-regs.h.
Rather than duplicating the same register bit masks for the RSTOUTn_MASK
and BRIDGE_CAUSE registers, move the definitions into the watchdog
driver itself.
