| 9 | * struct drxk_config - Configure the initial parameters for DRX-K | |
| 10 | * | |
| cd7a67a4 | 11 | * @adr: I2C address of the DRX-K |
| 67f04617 | 12 | * @parallel_ts: True means that the device uses parallel TS, |
| 534e0481 | 13 | * Serial otherwise. |
| 67f04617 MCC |
14 | * @dynamic_clk: True means that the clock will be dynamically |
| 15 | * adjusted. Static clock otherwise. | |
| d5856813 | 16 | * @enable_merr_cfg: Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG. |
| 67f04617 MCC |
17 | * @single_master: Device is on the single master mode |
| 18 | * @no_i2c_bridge: Don't switch the I2C bridge to talk with tuner | |
| 19 | * @antenna_gpio: GPIO bit used to control the antenna | |
| 20 | * @antenna_dvbt: GPIO bit for changing antenna to DVB-C. A value of 1 | |
| 90796aca | 21 | * means that 1=DVBC, 0 = DVBT. Zero means the opposite. |
| 6fb65a66 | 22 | * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength. |
| 67f04617 | 23 | * @microcode_name: Name of the firmware file with the microcode |
| 9e23f50a MB |
24 | * @qam_demod_parameter_count: The number of parameters used for the command |
| 25 | * to set the demodulator parameters. All | |
| 26 | * firmwares are using the 2-parameter commmand. | |
| 27 | * An exception is the "drxk_a3.mc" firmware, | |
| 28 | * which uses the 4-parameter command. | |
| 29 | * A value of 0 (default) or lower indicates that | |
| 30 | * the correct number of parameters will be | |
| 31 | * automatically detected. | |
| 90796aca MCC |
32 | * |
| 33 | * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is | |
| 34 | * UIO-3. | |
