snd_ac97_mixer(9) [centos man page]

SND_AC97_MIXER(9)						 Control/Mixer API						 SND_AC97_MIXER(9)

NAME
snd_ac97_mixer - create an Codec97 component SYNOPSIS
int snd_ac97_mixer(struct snd_ac97_bus * bus, struct snd_ac97_template * template, struct snd_ac97 ** rac97); ARGUMENTS
bus the AC97 bus which codec is attached to template the template of ac97, including index, callbacks and the private data. rac97 the pointer to store the new ac97 instance. DESCRIPTION
Creates an Codec97 component. An struct snd_ac97 instance is newly allocated and initialized from the template. The codec is then initialized by the standard procedure. The template must include the codec number (num) and address (addr), and the private data (private_data). The ac97 instance is registered as a low-level device, so you don't have to release it manually. RETURN
Zero if successful, or a negative error code on failure. COPYRIGHT

I2C_ADD_NUMBERED_ADA(9) 				      I2C and SMBus Subsystem					   I2C_ADD_NUMBERED_ADA(9)

NAME
i2c_add_numbered_adapter - declare i2c adapter, use static bus number SYNOPSIS
int i2c_add_numbered_adapter(struct i2c_adapter * adap); ARGUMENTS
adap the adapter to register (with adap->nr initialized) CONTEXT
can sleep DESCRIPTION
This routine is used to declare an I2C adapter when its bus number matters. For example, use it for I2C adapters from system-on-chip CPUs, or otherwise built in to the system's mainboard, and where i2c_board_info is used to properly configure I2C devices. If the requested bus number is set to -1, then this function will behave identically to i2c_add_adapter, and will dynamically assign a bus number. If no devices have pre-been declared for this bus, then be sure to register the adapter before any dynamically allocated ones. Otherwise the required bus ID may not be available. When this returns zero, the specified adapter became available for clients using the bus number provided in adap->nr. Also, the table of I2C devices pre-declared using i2c_register_board_info is scanned, and the appropriate driver model device nodes are created. Otherwise, a negative errno value is returned.
