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 * @dynamic_clk:	True means that the clock will be dynamically
14 *			adjusted. Static clock otherwise.
15 * @enable_merr_cfg:	Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG.
16 * @single_master:	Device is on the single master mode
17 * @no_i2c_bridge:	Don't switch the I2C bridge to talk with tuner
18 * @antenna_gpio:	GPIO bit used to control the antenna
19 * @antenna_dvbt:	GPIO bit for changing antenna to DVB-C. A value of 1
20 *			means that 1=DVBC, 0 = DVBT. Zero means the opposite.
21 * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength.
22 * @microcode_name:	Name of the firmware file with the microcode
23 *
24 * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
25 * UIO-3.
