[PATCH 0/4] Make turris-omnia-mcu driver parts optional

[Marek Behún]

Hi Arnd,

this series solves the Kconfig dependency issues of the turris-omnia-mcu
driver by making the GPIO, poweroff & wakeup, watchdog and TRNG parts of
the driver optional, under new Kconfig options. The dependencies to
subsystems are moved under these new options.

[PATCH 1/4] platform: cznic: turris-omnia-mcu: Make watchdog code optional

[Marek Behún]

Make the watchdog part of the driver optional, under a boolean config
option. Move the dependency to WATCHDOG to this new option, and change
the WATCHDOG_CORE dependency to selection, as is done in most watchdog
drivers.

This makes the turris-omnia-mcu driver available for compilation even if
WATCHDOG is disabled.
