/**
 * 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.
