   8  * struct drxk_config - Configure the initial parameters for DRX-K
   9  *
  10  * adr:                 I2C Address of the DRX-K
  11  * single_master:       Device is on the single master mode
  12  * no_i2c_bridge:       Don't switch the I2C bridge to talk with tuner
  13  * antenna_gpio:        GPIO bit used to control the antenna
  14  * antenna_dvbt:        GPIO bit for changing antenna to DVB-C. A value of 1
  15  *                      means that 1=DVBC, 0 = DVBT. Zero means the opposite.
  16  * microcode_name:      Name of the firmware file with the microcode
  17  *
  18  * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
  19  * UIO-3.
