+ * struct drxk_config - Configure the initial parameters for DRX-K
+ *
+ * adr:                 I2C Address of the DRX-K
+ * 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.
