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