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