It therefor saddens me to say that there's more to it... A builtin driver with module dependencies will through device links and probe deferral be probed once those resources are available, so this isn't the reason for us to mark these providers as built-in. Instead what we're looking for is the fact that we want the console to be registered before we launch userspace (and thereby load modules). The main reason for this is that e.g. systemd opens /dev/console at launch (i.e. when the init process starts). So if we registers the console after this, we will not get the console output from systemd. So, please rephrase this to state that we want these built-in, because the serial console driver depends on them and we want that registered before we launch userspace.

Enable clock controller, interconnect and pinctrl for Qualcomm QCS615 platform to boot to UART console. The serial engine depends on gcc, interconnect and pinctrl. Since the serial console driver is only available as built-in, so these configs needs be built-in for the UART device to probe and register the console.
