ALSA: ac97: split out the generic ac97 registers
Split out from the ac97_codec.h the ac97 generic registers, which can be used by a codec, typically a generic ac97 codec, and by the ac97 bus, to scan an ac97 AC-Link. This split encompasses all the AC97 standard registers, but not the codec specific ones. In order to have a clean split between former ac97 bus implementation and the new coming one in sound/ac97, it is safer to not include any former ac97 includes, excepting in sound/ac97/compat.c. Amongst the thing to isolate : - don't have the struct snd_ac97 in sound/ac97/* (except compat.c) to not be "fooled" by a definition which would come with ac97_codec.h by "chance". - don't have to have snd_a97_*() functions, as they rely on struct snd_ac97. - don't want the struct snd_ac97_bus_ops, there is a new one Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
