9 * struct drxk_config - Configure the initial parameters for DRX-K
10 *
Mauro Carvalho Chehabcd7a67a2013-04-28 11:47:44 -0300[diff] [blame]11 * @adr: I2C address of the DRX-K
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]12 * @parallel_ts: True means that the device uses parallel TS,
Mauro Carvalho Chehab534e0482011-07-24 14:59:20 -0300[diff] [blame]13 * Serial otherwise.
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]14 * @dynamic_clk: True means that the clock will be dynamically
15 * adjusted. Static clock otherwise.
Mauro Carvalho Chehabd5856812012-01-21 07:57:06 -0300[diff] [blame]16 * @enable_merr_cfg: Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG.
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]17 * @single_master: Device is on the single master mode
18 * @no_i2c_bridge: Don't switch the I2C bridge to talk with tuner
19 * @antenna_gpio: GPIO bit used to control the antenna
20 * @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]21 * means that 1=DVBC, 0 = DVBT. Zero means the opposite.
Mauro Carvalho Chehab6fb65a62012-01-20 19:13:07 -0300[diff] [blame]22 * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength.
Mauro Carvalho Chehab67f04612012-01-20 18:30:58 -0300[diff] [blame]23 * @microcode_name: Name of the firmware file with the microcode
Martin Blumenstingl9e23f50a2012-07-04 17:36:55 -0300[diff] [blame]24 * @qam_demod_parameter_count: The number of parameters used for the command
25 * to set the demodulator parameters. All
26 * firmwares are using the 2-parameter commmand.
27 * An exception is the "drxk_a3.mc" firmware,
28 * which uses the 4-parameter command.
29 * A value of 0 (default) or lower indicates that
30 * the correct number of parameters will be
31 * automatically detected.
Mauro Carvalho Chehab8e307832012-10-02 16:01:15 -0300[diff] [blame]32 * @load_firmware_sync: Force the firmware load to be synchronous.
Mauro Carvalho Chehab90796ac2011-07-10 09:36:30 -0300[diff] [blame]33 *
34 * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
35 * UIO-3.
