6dbe662874 [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.

02856b5684 [ALSA] AD1888 mixer controls for DC mode
This patch adds two mixer controls. The V_REFOUT enable is a
documented register that couples the microphone input lines
to the V_REFOUT DC source. The High Pass Filter enable in the
AC97_AD_TEST2 (0x5c) is an undocumented register provided by
Miller Puckette via Analog Devices that enables the AD codec
to apply a high pass filter to the input.

1459c7849e [ALSA] Disable AC97 AUX and VIDEO controls for WM9705 touchscreen
This patch by Rodolfo Giometti disables the AC97 AUX and VIDEO controls
on the WM9705 when the touchscreen is selected as the AUX and VIDEO
lines are shared with the touch controller.
Changes:-
 o Added AC97_HAS_NO_AUX flag
 o Test for AC97_HAS_NO_AUX flag in snd_ac97_mixer_build()
 o Sets AC97_HAS_NO_VIDEO and AC97_HAS_NO_AUX in patch_wolfson05() when
WM9705 touch driver is selected.

50dabc2d11 [ALSA] ac97 - Add support of static resolution tables
Modules: AC97 Codec

Added the support of static resolution table support for codecs
that the driver cannot probe the volume resolution properly.

The table pointer should be set in each codec patch.

a0faefedf7 [ALSA] Add a new quirk for mute-LED and HP-only.
Modules: AC97 Codec,ATIIXP driver,Intel8x0 driver

This patch adds a new quirk for ac97 hardware that combines the existing
AC97_TUNE_MUTE_LED and AC97_TUNE_HP_ONLY quirks.  This is needed for several
current HP laptops.  Additionally, it adds the HP nx6125 to the
AC97_TUNE_MUTE_LED list.

Fixed for the latest version of ALSA by Takashi Iwai <tiwai@suse.de>.

72e75de2df [ALSA] remove redundent assignment to the ac97 device structure
AC97 Codec
Don't use dev.platform_data to store a reference to the containing
ac97_t structure.  Such assignment is redundent since we can deduce the
ac97_t structure location from the contained device structure.  This
sets platform_data free for other purposes.

0ca06a00e2 [ALSA] AC97 bus interface for ad-hoc drivers
AC97 Codec,PCI drivers
I've made the review changes and as requested I've pasted the RFC by
Nicolas below:-

'I would like to know what people think of the following patch.  It
allows for a codec on an AC97 bus to be shared with other drivers which
are completely unrelated to audio.  It registers a new bus type, and
whenever a codec instance is created then a device for it is also
registered with the driver model using that bus type.  This allows, for
example, to use the extra features of the UCB1400 like the touchscreen
interface and the additional GPIOs and ADCs available on that chip for
battery monitoring.  I have a working UCB1400 touchscreen driver here
that simply registers with the driver model happily working alongside
with audio features using this.'

Changes over RFC:-

  o Now matches codec name within codec group.
  o Added ac97_dev_release() to stop kernel complaining about no release
method for device.
  o Added 'config SND_AC97_BUS' to sound/pci/Kconfig and moved 'config
SND_AC97_CODEC' out with the PCI=n statement.
  o module is now called snd-ac97-bus

eb8caf30f4 [ALSA] Improve the shared-jack handling on ac97
AC97 Codec
The handling of shared surround/clfe output jacks with line/mic-in
on some AC97 codecs is improved.

Instead of 'Line-In As Surround' or 'Mic As Center/LFE' switch, two
new enum controls are introduced: 'Channel Mode' and 'Surround Jack Mode'.
The formar changes the current output mode among 2, 4 and 6-channels.
The latter controls whether the jacks are shared or independent.

Linus Torvalds
1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
