* TODO:
* - add smart card reader support for Conditional Access (CA)
*
* Card reader in Anysee is nothing more than ISO 7816 card reader.
* There is no hardware CAM in any Anysee device sold.
* In my understanding it should be implemented by making own module
* for ISO 7816 card reader, like dvb_ca_en50221 is implemented. This
* module registers serial interface that can be used to communicate
* with any ISO 7816 smart card.
*
* Any help according to implement serial smart card reader support
* is highly welcome!
