 * 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!
