So far we create only "Capture Volume" and "Capture Switch" controls
for binding all possible amps, but we'd prefer creating individual
capture volume and switch controls per input in some cases
(e.g. conexant parser does it).

Add a new flag, spec->multi_cap_vol, to follow that policy.

There are a few more cases where we can assign "Master" mixer element
safely, e.g. when a single DAC is used in the whole output paths.

Also, when vmaster hook is present, avoid "Master" but assign "PCM"
instead.  Otherwise vmaster hook won't work properly.

Now we reached to the final big piece of parser rewrite: the input
paths.  While the old parser code assumes the more-or-less direct and
similar connections from input pin to ADC, the new code handles the
complete input paths.  The capture source is switched by simple calls
of activate_path() function.

The parsing of capture volume and capture switches is, however, not
fully generalized.  It assumes that amps are available in the vicinity
of ADCs (in three depth).  This isn't perfect but it should cover all
codecs I know of.

Also, this commit removes some NID mapping of capture-related controls
temporarily for simplicity.  It'll be restored in later commits.

... and rewrite the initialization of output paths as a generic

The new flag, active, is introduced to each nid_path entry.  This
indicates whether the given path is active, and it's used for checking

no longer used or newly enabled.

It's still used only in the output paths.  More wider adaption for

When initializing the output paths, we assumed the input amps have
almost two inputs blindly.  It's not only generic but even incorrect
for some codecs like ALC268 & co.  Also, the same assumption (two

This patch changes the codes in these places to handle the input
connections in a more generic way.

Improve the parser of analog loopback paths and handle in a more

- Instead of assuming direct connections between pins and
  the mixer widget, track the whole path between them.  This fixes

- Introduce the path list for loopback paths like input and output
  path lists.  Currently it's not used for any real purposes, yet.

Just like the output paths, parse the whole paths for inputs as well
and store in a path list.  For that purpose, rewrite the output parser

So far, idx[i] and multi[i] indicate the attribute of the widget
path[i - 1].  This was just for simplifying the code in
__parse_output_path(), but this is rather confusing for later use.
It's more natural if both idx[i] and multi[i] point to the same widget
of path[i].  This patch changes to that way.

Simplify the output path initialization using the existing path
information instead of assuming the topology specific to Realtek
codecs.  This is also implicitly a fix for some amp values on output
pins where the old parser missed (e.g. ALC260 output pins).

The same function alc_auto_set_output_and_unmute() can be used now for
the multi-io activation, since the output selection means nothing but
activating the given output path.

And, finally at this stage, we can get rid of alc_go_down_to_selector()
and other functions that are codec really specifically to Realtek
codecs.

So far, Realtek codec driver evaluates the NIDs for volume and mute
controls twice, once while parsing the DACs and evaluating the
assignment, and another while creating the mixer elements.  This is
utterly redundant and even fragile, as it's assuming that the ctl
element evaluation is identical between both parsing DACs and creating
mixer elements.

This patch simplifies the code flow by doing the volume / mute
controls evaluation only once while parsing the DACs.  The patch ended
up in larger changes than expected because of some cleanups became
mandatory.

As a gratis bonus, this patch also fixes some cases where the stereo
channels are used wrongly for mono amps.

As we parse the output paths more precisely now, we can use this path
list for parsing the widgets for volume and mute mixer controls.
The spec->vol_ctls[] and sw_ctls[] bitmasks are replaced with the
ctls[] in each output path instance.

Interestingly, this move alone automagically fixes some bugs that the
conflicting volume or mute NIDs weren't properly detected.
Also, by parsing the whole path, there are more chances to get a free
widget for volume/mute controls.

Add the output path parser to Realtek codec driver as we already have
in patch_via.c.  The nid_path struct represents the complete output
path from a DAC to a pin.  The alc_spec contains an array of these
paths, and a new path is added at each time when a new DAC is
assigned.

So far, this path list is used only in limited codes: namely in this
patch, only alc_is_dac_already_used() checks the list instead of dac
arrays in all possible outputs.  In the later development, the path
list will be referred from more places, such as the mixer control
assignment / check, the mute/unmute of active routes, etc.

The current Realtek driver reconfigures the max PCM channels
dynamically according to the value of Channel Mode enum if the
multi-io retasking is available.  It works fine for multi-io pins.
But when multiple speaker pins are available, the channels of speakers
also have to obey to the channel mode, which isn't nice.
(That is, when you select "2ch" in Channel Mode so that the line-in
 and mic jack behave as input, you can't play surrounds properly from
 the built-in speaker.)

This patch fixes the problem by taking the channel number for multiple
speakers into account in the channel-mode setup code.
Also it fixes the wrongly set up max_channels value in the case of
multi-io extension.
