[ALSA] ac97: YMF743 missing controls support (2/2)
These patches enable a few YMF743 controls (Tone/3D/IEC958) that won't be detected with the current version of ALSA. The second one contains following changes: - A chip-specific SPDIF support for YMF743 (It doesn't have AC97 standard SPDIF registers seen on YMF753). - The implementation for 'IEC958 Playback Source' and 'IEC958 Mute' are identical to the ones for YMF753. But there is no 'IEC958 Output Pin' for YMF743. Signed-off-by: Keita Maehara <maehara@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
