8 * struct drxk_config - Configure the initial parameters for DRX-K
9 *
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]10 * @adr: I2C Address of the DRX-K
11 * @parallel_ts: True means that the device uses parallel TS,
Mauro Carvalho Chehab534e0482011-07-24 14:59:20 -0300[diff] [blame]12 * Serial otherwise.
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]13 * @dynamic_clk: True means that the clock will be dynamically
14 * adjusted. Static clock otherwise.
15 * @single_master: Device is on the single master mode
16 * @no_i2c_bridge: Don't switch the I2C bridge to talk with tuner
17 * @antenna_gpio: GPIO bit used to control the antenna
18 * @antenna_dvbt: GPIO bit for changing antenna to DVB-C. A value of 1
Mauro Carvalho Chehab90796ac2011-07-10 09:36:30 -0300[diff] [blame]19 * means that 1=DVBC, 0 = DVBT. Zero means the opposite.
Mauro Carvalho Chehab6fb65a62012-01-20 19:13:07 -0300[diff] [blame^]20 * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength.
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]21 * @microcode_name: Name of the firmware file with the microcode
Mauro Carvalho Chehab90796ac2011-07-10 09:36:30 -0300[diff] [blame]22 *
23 * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
24 * UIO-3.
