X-Patchwork-Delegate: mchehab@redhat.com Thare are lots of CamelCase warnings produced by checkpatch.pl. This weren't fixed at the time the driver got submitted due to the lack of manpower do to such cleanup. Now that I have one script that automates this task, cleans it. That makes the driver almost checkpatch-compliant, except for 80 column warnings. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

/**
|
|
* 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.
|
|
* @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.
|
|
* @load_firmware_sync: Force the firmware load to be synchronous.
|
|
*
|
|
* On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
|
|
* UIO-3.
