A question here about the builtin_platform_driver() use in this driver,
especially since it's set as tristate in Kconfig, thus I am not sure if
using builtin_platform_driver() over module_platform_driver() is correct?

Unless this is more because you need to reply on device_initcall() for the
driver to properly initialise?

Otherwise,
