bool "Enable driver model for watchdog timer drivers"
depends on DM
watchdog: Implement generic watchdog_reset() version This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.
