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. Acked-by:

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. Signed-off-by:

Commit 0dfd582e ("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. Signed-off-by:

Tim Harvey authored
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.

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.
