snd_ac97_bus: create an AC97 bus component
NAME
snd_ac97_bus - create an AC97 bus component
SYNOPSIS
-
int snd_ac97_bus(struct snd_card
* card, intnum, struct snd_ac97_bus_ops * ops, void* private_data, struct snd_ac97_bus** rbus);
ARGUMENTS
card
-
- the card instance
num
- the bus number
ops
- the bus callbacks table
private_data
- private data pointer for the new instance
rbus
- the pointer to store the new AC97 bus instance.
DESCRIPTION
Creates an AC97 bus component. An struct snd_ac97_bus instance is newly allocated and initialized.
The ops table must include valid callbacks (at least read and write). The other callbacks, wait and reset, are not mandatory.
The clock is set to 48000. If another clock is needed, set (*rbus)->clock manually.
The AC97 bus 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.
