  20  * TODO:
  21  * - add smart card reader support for Conditional Access (CA)
  22  *
  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.
  29  *
  30  * Any help according to implement serial smart card reader support
  31  * is highly welcome!
