+/**
+ * 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.
+ * @chunk_size: maximum size for I2C messages
+ * @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.
