/**
|
|
* struct drxk_config - Configure the initial parameters for DRX-K
|
|
*
|
|
* @adr: I2C address of the DRX-K
|
|
* @parallel_ts: True means that the device uses parallel TS,
|
|
* Serial otherwise.
|
|
* @dynamic_clk: True means that the clock will be dynamically
|
|
* adjusted. Static clock otherwise.
|
|
* @enable_merr_cfg: Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG.
|
|
* @single_master: Device is on the single master mode
|
|
* @no_i2c_bridge: Don't switch the I2C bridge to talk with tuner
|
|
* @antenna_gpio: GPIO bit used to control the antenna
|
|
* @antenna_dvbt: GPIO bit for changing antenna to DVB-C. A value of 1
|
|
* means that 1=DVBC, 0 = DVBT. Zero means the opposite.
|
|
* @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength.
|
|
* @chunk_size: maximum size for I2C messages
|
|
* @microcode_name: Name of the firmware file with the microcode
|
|
* @qam_demod_parameter_count: The number of parameters used for the command
|
|
* to set the demodulator parameters. All
|
|
* firmwares are using the 2-parameter commmand.
|
|
* An exception is the ``drxk_a3.mc`` firmware,
|
|
* which uses the 4-parameter command.
|
|
* A value of 0 (default) or lower indicates that
|
|
* the correct number of parameters will be
|
|
* automatically detected.
|
|
*
|
|
* On the ``*_gpio`` vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
|
|
* UIO-3.
