 * tveeprom - Contains structures and functions to work with Hauppauge
 *            eeproms.

#include <linux/if_ether.h>

 * enum tveeprom_audio_processor - Specifies the type of audio processor
 *                                 used on a Hauppauge device.
 * @TVEEPROM_AUDPROC_NONE:      No audio processor present
 * @TVEEPROM_AUDPROC_INTERNAL:  The audio processor is internal to the
 *                              video processor
 * @TVEEPROM_AUDPROC_MSP:       The audio processor is a MSPXXXX device
 * @TVEEPROM_AUDPROC_OTHER:     The audio processor is another device

enum tveeprom_audio_processor {

 * struct tveeprom - Contains the fields parsed from Hauppauge eeproms
 * @has_radio:                  1 if the device has radio; 0 otherwise.
 * @has_ir:                     If has_ir == 0, then it is unknown what the IR
 *                              capabilities are. Otherwise:
 *                              bit 0) 1 (= IR capabilities are known);
 *                              bit 1) IR receiver present;
 *                              bit 2) IR transmitter (blaster) present.
 * @has_MAC_address:            0: no MAC, 1: MAC present, 2: unknown.
 * @tuner_type:                 type of the tuner (TUNER_*, as defined at
 *                              include/media/tuner.h).
 * @tuner_formats:              Supported analog TV standards (V4L2_STD_*).
 * @tuner_hauppauge_model:      Hauppauge's code for the device model number.
 * @tuner2_type:                type of the second tuner (TUNER_*, as defined
 *                              at include/media/tuner.h).
 * @tuner2_formats:             Tuner 2 supported analog TV standards
 *                              (V4L2_STD_*).
 * @tuner2_hauppauge_model:     tuner 2 Hauppauge's code for the device model
 *                              number.
 * @audio_processor:            analog audio decoder, as defined by enum
 *                              tveeprom_audio_processor.
 * @decoder_processor:          Hauppauge's code for the decoder chipset.
 *                              Unused by the drivers, as they probe the
 *                              decoder based on the PCI or USB ID.
 * @model:                      Hauppauge's model number
 * @revision:                   Card revision number
 * @serial_number:              Card's serial number
 * @rev_str:                    Card revision converted to number
 * @MAC_address:                MAC address for the network interface
