'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Describe device tree optional properties:
* aspeed,reset-type = "cpu|soc|system|none"
One of three different, mutually exclusive, values
"cpu" : ARM CPU reset on signal
"soc" : 'System on chip' reset
"system" : Full system reset
The value can also be set to "none" which indicates that no
reset of any kind is to be done via this watchdog. This assumes
another watchdog on the chip is to take care of resets.

The watchdog IP block on Meson8 and Meson8m2 is already supported by the
existing meson-wdt driver. Meson8 uses the same register bits as Meson6,
while the newer Meson8m2 SoC uses the same register bits as Meson8b.
Currently watchdog support on Meson8 SoC already works because
meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a
separate compatible for Meson8 makes this more explicit though.

In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt. However the interrupt itself was not cleared thus on
first hit, the system enters infinite interrupt handling loop.
On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1
argument the console is flooded:
# killall -9 watchdog
[ 60.523760] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
[ 60.536744] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
Fix this by writing something to the WTCLRINT register to clear the
interrupt. The register WTCLRINT however appeared in S3C6410 so a new
watchdog quirk and flavor are needed.

Commit 0dfd582e02 ("watchdog: qcom: use timer devicetree
binding") moved to use the watchdog as a subset timer
register block. Some devices have the watchdog completely
standalone with slightly different register offsets as
well so let's account for the differences here.
The existing "kpss-standalone" compatible string doesn't
make it entirely clear exactly what the device is so
rename to "kpss-wdt" to reflect watchdog timer
functionality. Also update ipq4019 DTS with an SoC
specific compatible.

The IMX6 watchdog supports assertion of a signal (WDOG_B) which
can be pinmux'd to an external pin. This is typically used for boards that
have PMIC's in control of the IMX6 power rails. In fact, failure to use
such an external reset on boards with external PMIC's can result in various
hangs due to the IMX6 not being fully reset [1] as well as the board failing
to reset because its PMIC has not been reset to provide adequate voltage for
the CPU when coming out of reset at 800Mhz.
This uses a new device-tree property 'fsl,ext-reset-output' to indicate the
board has such a reset and to cause the watchdog to be configured to assert
WDOG_B instead of an internal reset both on a watchdog timeout and in
system_restart.

- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)

Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new

This watchdog is instantiated in a FPGA that is memory mapped. It is
made of only one register, called the feed register. Writing to this
register will re-arm the watchdog for a given time (and enable it if it
was disable). It can be disabled by writing a special value into it.
It is part of a syscon block, and the watchdog register offset in this
block varies from board to board. This offset is passed in the syscon
property after the phandle to the syscon node.

atmel,idle-halt property should be used with care, it actually makes the
watchdog not counting when the CPU is in idle state, therefore the
watchdog reset time depends on mean CPU usage and will not reset at all
of the CPU stop working while it is in idle state, which is probably not
what you want.
