* 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.
* 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.
* 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.
