#include <drxk.h>
struct drxk_config - Configure the initial parameters for DRX-K
: I2C Address of the DRX-K : True means that the device uses parallel TS, Serial otherwise. : True means that the clock will be dynamically adjusted. Static clock otherwise. : Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG. : Device is on the single master mode : Don't switch the I2C bridge to talk with tuner : GPIO bit used to control the antenna : GPIO bit for changing antenna to DVB-C. A value of 1 means that 1=DVBC, 0 = DVBT. Zero means the opposite. : DRXK Mpeg output clock drive strength. : Name of the firmware file with the microcode : 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. : 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.
