Leandro Pereira 158ea970ea drivers: watchdog: Use common name configuration for all drivers
Each driver seemed to use their own Kconfig option to set the name for
their drivers.  This makes writing example/test code difficult as each
one of them will have to special case for each of the supported
platforms.

Use a consistent CONFIG_WDT_0_NAME option in all drivers.

Fixes #8094.

Leandro Pereira eefeb2b050 drivers: watchdog: esp32: Use common Kconfig option to disable at boot
Instead of relying on CONFIG_WDT_ESP32_DISABLE_AT_BOOT, use
CONFIG_WDT_DISABLE_AT_BOOT that's available for all watchdog timers.

Michał Kruszewski 0c2ef4ea3d drivers: watchdog: Watchdog API redesign
New API enables setting watchdog timeout in the unit of microseconds.
It is possible to configure watchdog timer behavior in CPU sleep state
as well as when it is halted by the debugger.
It supports watchdogs with multiple reload channels.

Leandro Pereira 5f22dab17a esp32: Prefix ROM routines with `esp32_rom_`
Also provide their prototypes in `soc.h`.  This should help
readability, since some ROM functions, with their names as provided by
Espressif, have sometimes the same prefix as Zephyr APIs.

Leandro Pereira 9bacdbac30 drivers: watchdog: esp32: Always use Timer Group 1 for WDT
The FreeRTOS port by Espressif uses the same timer group.  Do the same
here.

Leandro Pereira d52de29fba esp32: Fix redefinition of BIT() macro
Esp-idf defines the BIT macro that is also defined in Zephyr's
misc/util.h.  Fix the issue by including the esp-idf headers first, so
that a check in util.h won't redefine the macro if it's already
defined.

Leandro Pereira d691045592 drivers: watchdog: Implement ESP32 watchdog driver
Zephyr's watchdog API is badly designed in the sense that it's a 1:1
abstraction on top of whatever Quark D2000 expects for its watchdog,
instead of expecting a generic timeout value.

This implementation tries as much as possible to calculate the watchdog
timeout in a way that's compatible with a Quark D2000 running at 32MHz;
a comment in adjust_timeout() explains this in more detail.
