IXP4xx Watchdog found in drivers/watchdog/Kconfig

The configuration item CONFIG_IXP4XX_WATCHDOG:

• prompt: IXP4xx Watchdog
• type: tristate
• depends on: CONFIG_ARCH_IXP4XX || ( CONFIG_ARM && CONFIG_COMPILE_TEST )
• defined in drivers/watchdog/Kconfig
• found in Linux kernels: 2.6.24–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12
• modules built: ixp4xx_wdt, ixp4xx_wdt

Help text

Say Y here if to include support for the watchdog timer in the Intel IXP4xx network processors. This driver can be built as a module by choosing M. The module will be called ixp4xx_wdt.

Note: The internal IXP4xx watchdog does a soft CPU reset which doesn't reset any peripherals. There are circumstances where the watchdog will fail to reset the board correctly (e.g., if the boot ROM is in an unreadable state).

Say N if you are unsure.
