Harini T 35a3ddaa09 dts: bindings: watchdog: Add Xilinx Window Watchdog Timer
Xilinx Window Watchdog Timer IP uses window mode.
Window watchdog timer(WWDT) contains closed(first) and open(second)
window with 32 bit width each. Write to the watchdog timer within
predefined window periods of time. This means a period that is not too
soon and a period that is not too late.

The WWDT error interrupts (IRQs) occur when the watchdog timer is not
serviced within the predefined window periods. These IRQs are routed to
the Processing System Manager (PSM) error accumulator module. The PSM is
responsible for managing power and system-level errors, generating a
System on Chip (SoC) reset when a WWDT error occurs. The system reset
event is signaled as a system error for the PSM firmware to handle and a
reset output signal to the MIO/EMIO.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
