* adr: I2C Address of the DRX-K
* parallel_ts: true means that the device uses parallel TS,
* @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
* @dynamic_clk: True means that the clock will be dynamically
* adjusted. Static clock otherwise.

* @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.
