The Kconfig for this driver is: config RTD119X_WATCHDOG bool "Realtek RTD118x/RTD129x watchdog support" ...and hence it doesn't need to include module.h for anything. There are no other signs of unused modular infrastructure.

The Kconfig currently controlling compilation of this code is: config INTEL_SCU_WATCHDOG bool "Intel SCU Watchdog for Mobile Platforms" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We leave the moduleparam.h include since the file does declare some module parameters, and leaving them as such is currently the easiest way to remain compatible with existing boot arg use cases.

The Kconfig currently controlling compilation of this code is: config COH901327_WATCHDOG bool "ST-Ericsson COH 901 327 watchdog" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_ALIAS is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with moduleparam.h since the file does actually declare some module parameters (i.e. boot args for non-modules).

We have a default timeout value in the driver which we will fall back to if the user supplied values are out of bounce. Reviewed-by:

This not only removes boilerplate code from watchdog drivers, it can also be more specific which of the supplied value actually fails. Also, the loglevel becomes now consistent across drivers. Reviewed-by:

The function is not easy to read and has a problem: -EINVAL is returned when the module parameter is invalid but the DT parameter is OK. Refactor the code to have the same pattern of checks for the module parameter and DT. Further ones can be easily added in the future if the need arises. The above mentioned problem is fixed, too. Some documentation is added to describe the different handlings of '0' for the module parameter and the DT property. Reviewed-by:

Readout the enabled state so it is possible to get the pre-userspace handler working. Also, avoid disabling the watchdog to ensure it continues working and triggers if there is an issue later in the boot or if userspace fails to start. Signed-off-by:

Introduce local variable 'struct device *dev' and use it instead of dereferencing it repeatedly. Also, there is no call to dev_get_drvdata() or platform_get_drvdata() in the driver, so drop the unnecessary call to platform_set_drvdata().
