| /** | |
| * struct drxk_config - Configure the initial parameters for DRX-K | |
| * | |
| * @adr: I2C address of the DRX-K | |
| * @parallel_ts: True means that the device uses parallel TS, | |
| * Serial otherwise. | |
| * @dynamic_clk: True means that the clock will be dynamically | |
| * adjusted. Static clock otherwise. | |
| * @enable_merr_cfg: Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG. | |
| * @single_master: Device is on the single master mode | |
| * @no_i2c_bridge: Don't switch the I2C bridge to talk with tuner | |
| * @antenna_gpio: GPIO bit used to control the antenna | |
| * @antenna_dvbt: GPIO bit for changing antenna to DVB-C. A value of 1 | |
| * means that 1=DVBC, 0 = DVBT. Zero means the opposite. | |
| * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength. | |
| * @microcode_name: Name of the firmware file with the microcode | |
| * @qam_demod_parameter_count: The number of parameters used for the command | |
| * to set the demodulator parameters. All | |
| * firmwares are using the 2-parameter commmand. | |
| * An exception is the "drxk_a3.mc" firmware, | |
| * which uses the 4-parameter command. | |
| * A value of 0 (default) or lower indicates that | |
| * the correct number of parameters will be | |
| * automatically detected. | |
| * | |
| * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is | |
| * UIO-3. | |
