There are some mfd devices which supports junction thermal interruptAny comment please?
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.
