The former utilizes platform_driver_register(), which allows the driver to defer probing when it doesn't acquire the necessary resources due to probe order. In contrast, the latter uses __platform_driver_probe(), which includes the comment "Note that this is incompatible with deferred probing." Since our GPIO driver requires access to the clock resource, the former is more suitable.
