Even if the outputs are using shared DACs, we can still create individual
mute siwtches since they are assigned per pin.  This allows to create,
e.g. Speaker and Bass Speaker mute switches while the single volume is
used for these outputs.

Finally the all static quirks for ALC880 are converted to the
auto-parser.  Since we are never sure whether the BIOS on so many old
machines are really correct, the quirk table entries are copied as
they are, but just providing the proper pin-config values
accordingly.

Since alc880_quirks.c is removed, alc882_quirks.c has to be adjusted
slightly to be built again.  There might be some compile warnings due
to the remaining alc882 quirks, but these shall be killed sooner or
later, I don't care it much at this point.

ALC880 model=lg could work fine with the auto-parser due to the recent

So far, the Realtek driver tires to assign the single-connected routes
for all pins only once at the beginning.  However, since some DACs have
been already mapped, the rest pins might have also single conections.

In this patch, the driver does the single-connection assignment in a
loop until all possbile single-connections are checked.  This will
improve the DAC assignment, e.g. for ASUS G72.

This patch improves the Realtek auto-parser for assigning the DACs and
mixers in more suitable ways by evaluating the assignment with "badness"
calculations.

When assigning a DAC hinders the assignment of individual DACs for
other pins, some badness point is given.  Similarly, when it blocks the
assignment of unique mixer controls, another badness point is added.
Also, if no DAC, even shared DAC, can be assigned, more badness is
pointed.  Finally, comparing the accumulated badness, the best route is
chosen among several trials.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

When the connections from the pin selector contain only two
widgets, a route to DAC and the aa-mixer, it's certainly a
single connection.  In such a case, get_dac_if_single() should
return the connected DAC, too.

This will improve the detection of the individual DAC
assignment for each pin.

The fix for bitmap-overflow in Realtek codec driver is needed for the
further development of the auto-parser with badness evaluation.

The bitmap introduced in the commit [527e4d73: ALSA: hda/realtek - Fix
missing volume controls with ALC260] is too narrow for some codecs,
which may have more NIDs than 0x20, thus it may overflow the bitmap
array on them.

Just double the number to cover all and also add a sanity-check code
to be safer.

The support for Replacer 627V in the auto-parser needs the unique unsol

A simple fix from Morimoto-san for the pointer() operation in the FSI
driver.

Conflicts:
	sound/pci/hda/patch_realtek.c

Merged back the fix for Acer Aspire 6935 with ALC889 codec.
The fix commit was based on 3.2 kernel so that it can be applied to
stable kernel cleanly.

Since 3.2 kernel, the driver starts trying to assign the multi-io DACs
before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for
the speaker for a standard laptop setup like a HP, a speaker, a mic-in
and a line-in.  However, on Acer Aspire 6935, it seems that the
speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it
results in silence by some reason, although the codec itself allows
the routing to DAC3/4.

As a workaround, the connection list of each pin is reduced to be
mapped to either only DAC1/2 or DAC3/4, so that the compatible
assignment as in kernel 3.1 is achieved.
