16  * TODO:
17  * - add smart card reader support for Conditional Access (CA)
18  *
19  * Card reader in Anysee is nothing more than ISO 7816 card reader.
20  * There is no hardware CAM in any Anysee device sold.
21  * In my understanding it should be implemented by making own module
22  * for ISO 7816 card reader, like dvb_ca_en50221 is implemented. This
23  * module registers serial interface that can be used to communicate
24  * with any ISO 7816 smart card.
25  *
26  * Any help according to implement serial smart card reader support
27  * is highly welcome!
