2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai1-2/+0
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2008-01-31[ALSA] [ML403-AC97CR] Fix capture/periodic overrun bugJoachim Foerster1-18/+2
We have to do fairly accurate counting of the minimal periods, instead of being lazy and just setting the number to zero as soon as one period elapses. Signed-off-by: Joachim Foerster <JOFT@gmx.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] Xilinx ML403 AC97 Controller Reference device driverJoachim Foerster1-0/+591
Add ALSA support for the opb_ac97_controller_ref_v1_00_a ip core found in Xilinx' ML403 reference design. Known issue: Currently this driver hits a WARN_ON_ONCE(1) statement in kernel/irq/resend.c (line 70). According to Linus (http://lkml.org/lkml/2007/8/5/5) this may be ignored, right? I haven't had a look into this 'problem' yet. Signed-off-by: Joachim Foerster <JOFT@gmx.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
