/**
* 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
*
* On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
* UIO-3.
