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.
