## Summary xtensa/esp32s2: Add xtwdt and rwdt support ## Impact Only ESP32S2 ## Testing ### RWDT Testing `esp32s2-saola-1:watchdog` config used with `RTC Watchdog Timer` option enabled under the `System Type → ESP32-S2 Peripheral Selection`. `wdog -i /dev/watchdog2` command applied. ### XTWDT Testing Modified version of `watchdog` example using `esp32s2-saola-1:watchdog` config with `ESP32S2_XTWDT` option under the `System Type -> ESP32-S2 Peripheral Selection`, `Watchdog Timer Support` option under the `Device Drivers → Timer Driver Support` and `RTC clock source (External 32kHz crystal)` or `External 32kHz oscillator at 32K_XN pin` choice under the `System Type -> RTC Configuration`. To simulate 32768hz clock output, another esp device used with [adjusted timer example](https://github.com/espressif/esp-idf/tree/master/examples/peripherals/timer_group/gptimer). Clock connected to external oscillator pin (GPIO15). `wdog -i /dev/watchdog3` command applied and during runtime clock connection removed. `IRQ 116` needs to be raised during the test. -- This is an automated message from the Apache Git Service.
