ffbb29d62d drivers/watchdog: Add optional ASPEED device tree properties
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.

  * aspeed,external-signal - Generate external signal (WDT1 and WDT2 only)
  * aspeed,alt-boot - Boot from alternate block on signal

43a64e81b2 watchdog: meson-wdt: add support for the watchdog on Meson8 and Meson8m2
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.

f66872b5be Documentation: devicetree: watchdog: da9062/61 watchdog timer binding
Add binding information for DA9062 and DA9061 watchdog.

Example bindings for both DA9062 and DA9061 devices are added. For
the DA9061 device, a fallback compatible line is added as a valid
combination of compatible strings.

The original binding for DA9062 (only) used to reside inside the
Documentation/devicetree/bindings/mfd/da9062.txt MFD document.
The da9062-watchdog section was deleted in that file and replaced
with a link to the new DA9061/62 binding information stored in this
patch.

0b445549ea watchdog: s3c2410: Fix infinite interrupt in soft mode
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.

f0d9d0f4b4 watchdog: qcom: add option for standalone watchdog not in timer block
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.

bc677ff42e watchdog: imx2_wdt: add external reset support via dt prop
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.

6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 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
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

ab3f09fe16 watchdog: add MT7621 watchdog support
This patch adds support for the watchdog core found on newer MediaTek Wifi
SoCs MT7621 and MT7628. There is no symbol for MT7628 as it is a subtype of
MT7620 so we depend on that instead.

bf90063999 watchdog: ts4800: add driver for TS-4800 watchdog
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.
