+ * 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 implented. This
+ * module registers serial interface that can be used to comminicate
+ * with any ISO 7816 smart card.
+ *
+ * Any help according to implement serial smart card reader support
+ * is highly welcome!
