[ALSA] Add experimental support of aggressive AC97 power-saving mode
Added CONFIG_SND_AC97_POWER_SAVE kernel config to enable the support of aggressive AC97 power-saving mode. In this mode, the AC97 powerdown register bits are dynamically controlled at each open/close of PCM streams. The mode is activated via power_save option for snd-ac97-codec driver. As default it's off. It can be turned on/off on the fly via sysfs, too. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
