There are some mfd devices which supports junction thermal interrupt like ams,AS3722. The DT binding of these devices are defined as the flat and drivers for sub module of such devices are registered as the mfd_add_devices. In this method, the sub devices registered as platform driver and these do not have the of_node pointer on their device structure. In this case, use the parent of_node pointer to get the required of_node pointer.
