* 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!
