d545a57c5f ALSA: hda - Sync node attributes at resume from widget power saving
So far we assumed that the node attributes like amp values remain
during the power state transition of the node itself.  While this is
true for IDT/STAC codecs I've tested, but some other codecs don't seem
behaving in that way.

This patch implements a partial sync mechanism specific to the given
widget node.  Now we've merged the regmap support, and it can be
easily written with regcache_sync_region().

a551d91473 ALSA: hda - Use regmap for command verb caches, too
Like the previous patches, this patch converts also to the regmap, at
this time, the cached verb writes are the target.  But this conversion
needs a bit more caution than before.

- In the old code, we just record any verbs as is, and restore them at
  resume.  For the regmap scheme, this doesn't work, since a few verbs
  like AMP or DIGI_CONVERT are asymmetrical.  Such verbs are converted
  either to the dedicated function (snd_hda_regmap_xxx_amp()) or
  changed to the unified verb.

- Some verbs have to be declared as vendor-specific ones before
  accessing via regmap.

Also, the minor optimization with codec->cached_write flag is dropped
in a few places, as this would confuse the operation.  Further
optimizations will be brought in the later patches, if any.

This conversion ends up with a drop of significant amount of codes,
mostly the helper codes that are no longer used.

faa75f8a2e ALSA: hda - Use regmap for parameter caches, too
The amp hash table was used for recording the cached reads of some
capability values like pin caps or amp caps.  Now all these are moved
to regmap as well.

One addition to the regmap helper is codec->caps_overwriting flag.
This is set in snd_hdac_override_parm(), and the regmap helper accepts
any register while this flag is set, so that it can overwrite even the
read-only verb like AC_VERB_PARAMETERS.  The flag is cleared
immediately in snd_hdac_override_parm(), as it's a once-off flag.

Along with these changes, the no longer needed amp hash and relevant
fields are removed from hda_codec struct now.

eeecd9d10d ALSA: hda - Use regmap for amp accesses
This patch converts the amp access functions to the regmap helpers.
The amp values were formerly cached in the own hash table.  Now it's
dropped by the regmap's cache.

The only tricky conversion is snd_hda_codec_amp_init().  This function
shouldn't do anything if the amp was already initialized.  For
achieving this behavior, a value is read once at first temporarily in
the cache-only mode.  Only if it returns an error,  i.e. the item
still doesn't exist in the cache, it proceeds to the update.

4d75faa044 ALSA: hda - Add regmap support
This patch adds an infrastructure to support regmap-based verb
accesses.  Because o the asymmetric nature of HD-audio verbs,
especially the amp verbs, we need to translate the verbs as a sort of
pseudo registers to be mapped uniquely in regmap.

In this patch, a pseudo register is built from the NID, the
AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent
to HD-audio bus but without codec address field.  OTOH, for writing,
the same pseudo register is translated to AC_VERB_SET_* automatically.
The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding
AC_VERB_GET_AMP_* verb and parameter at writing.

Some verbs has a single command for read but multiple for writes.  A
write for such a verb is split automatically to multiple verbs.

The patch provides also a few handy helper functions.  They are
designed to be accessible even without regmap.  When no regmap is set
up (e.g. before the codec device instantiation), the direct hardware
access is used.  Also, it tries to avoid the unnecessary power-up.
The power up/down sequence is performed only on demand.

The codec driver needs to call snd_hdac_regmap_exit() and
snd_hdac_regmap_exit() at probe and remove if it wants the regmap
access.

There is one flag added to hdac_device.  When the flag lazy_cache is
set, regmap helper ignores a write for a suspended device and returns
as if it was actually written.  It reduces the hardware access pretty
much, e.g. when adjusting the mixer volume while in idle.  This
assumes that the driver will sync the cache later at resume properly,
so use it carefully.

3256be6537 ALSA: hda - Add widget sysfs tree
This patch changes the sysfs files assigned to the codec device on the
bus which were formerly identical with hwdep sysfs files.  Now it
shows only a few core parameter, vendor_id, subsystem_id, revision_id,
afg, mfg, vendor_name and chip_name.

In addition, now a widget tree is added to the bus device sysfs
directory for showing the widget topology and attributes.  It's just a
flat tree consisting of subdirectories named as the widget NID
including various attributes like widget capability bits.  The AFG
(usually NID 0x01) is always found there, and it contains always
amp_in_caps, amp_out_caps and power_caps files.  Each of these
attributes show a single value.  The rest are the widget nodes
belonging to that AFG.  Note that the child node might not start from
0x02 but from another value like 0x0a.

Each child node may contain caps, pin_caps, amp_in_caps, amp_out_caps,
power_caps and connections files.  The caps (representing the widget
capability bits) always contain a value.  The rest may contain
value(s) if the attribute exists on the node.  Only connections file
show multiple values while other attributes have zero or one single
value.

An example of ls -R output is like below:
% ls -R /sys/bus/hdaudio/devices/hdaudioC0D0/

e6feb5d085 ALSA: hda - Support advanced power state controls
This patch enables the finer power state control of each widget
depending on the jack plug state and streaming state in addition to
the existing power_down_unused power optimization.  The new feature is
enabled only when codec->power_mgmt flag is set.

Two new flags, pin_enabled and stream_enabled, are introduced in
nid_path struct for marking the two individual power states: the pin
plug/unplug and DAC/ADC stream, respectively.  They can be set
statically in case they are static routes (e.g. some mixer paths),
too.

The power up and down events for each pin are triggered via the
standard hda_jack table.  The call order is hard-coded, relying on the
current implementation of jack event chain (a la FILO/stack order).

One point to be dealt carefully is that DAC/ADC cannot be powered
on/off while streaming.  They are pinned as long as the stream is
running.  For controlling the power of DAC/ADC, a new patch_ops is
added.  The generic parser provides the default callback for that.

As of this patch, only IDT/Sigmatel codec driver enables the flag.
The support on other codecs will follow.

An assumption we made in this code is that the widget state (e.g. amp,
pinctl, connections) remains after the widget power transition (not
about FG power transition).  This is true for IDT codecs, at least.
But if the widget state is lost at widget power transition, we'd need
to implement additional code to sync the cached amp/verbs for the
specific NID.

cc261738ad ALSA: hda - Treat stereo-to-mono mix properly
The commit [ef403edb75: ALSA: hda - Don't access stereo amps for
mono channel widgets] fixed the handling of mono widgets in general,
but it still misses an exceptional case: namely, a mono mixer widget
taking a single stereo input.  In this case, it has stereo volumes
although it's a mono widget, and thus we have to take care of both
left and right input channels, as stated in HD-audio spec ("7.1.3
Widget Interconnection Rules").

This patch covers this missing piece by adding proper checks of stereo
amps in both the generic parser and the proc output codes.

ef403edb75 ALSA: hda - Don't access stereo amps for mono channel widgets
The current HDA generic parser initializes / modifies the amp values
always in stereo, but this seems causing the problem on ALC3229 codec
that has a few mono channel widgets: namely, these mono widgets react
to actions for both channels equally.

In the driver code, we do care the mono channel and create a control
only for the left channel (as defined in HD-audio spec) for such a
node.  When the control is updated, only the left channel value is
changed.  However, in the resume, the right channel value is also
restored from the initial value we took as stereo, and this overwrites
the left channel value.  This ends up being the silent output as the
right channel has been never touched and remains muted.

This patch covers the places where unconditional stereo amp accesses
are done and converts to the conditional accesses.

workaround as MBP8,1 to spread the mono channel via a Cirrus codec
vendor-specific COEF setup.

bad994f5b4 ALSA: hda - Set single_adc_amp flag for CS420x codecs
CS420x codecs seem to deal only the single amps of ADC nodes even
though the nodes receive multiple inputs.  This leads to the
inconsistent amp value after S3/S4 resume, for example.

The fix is just to set codec->single_adc_amp flag.  Then the driver
handles these ADC amps as if single connections.

ddb6ca75b5 ALSA: hda - Fix built-in mic on Compaq Presario CQ60
Compaq Presario CQ60 laptop with CX20561 gives a wrong pin for the
built-in mic NID 0x17 instead of NID 0x1d, and it results in the
non-working mic.  This patch just remaps the pin correctly via fixup.

a1f3f1ca66 ALSA: hda - Fix regression of HD-audio controller fallback modes
The commit [63e51fd708: ALSA: hda - Don't take unresponsive D3
transition too serious] introduced a conditional fallback behavior to
the HD-audio controller depending on the flag set.  However, it
introduced a silly bug, too, that the flag was evaluated in a reverse
way.  This resulted in a regression of HD-audio controller driver
where it can't go to the fallback mode at communication errors.

Unfortunately (or fortunately?) this didn't come up until recently
because the affected code path is an error handling that happens only
on an unstable hardware chip.  Most of recent chips work stably, thus
they didn't hit this problem.  Now, we've got a regression report with
a VIA chip, and this seems indeed requiring the fallback to the
polling mode, and finally the bug was revealed.

The fix is a oneliner to remove the wrong logical NOT in the check.
(Lesson learned - be careful about double negation.)

The bug should be backported to stable, but the patch won't be
applicable to 3.13 or earlier because of the code splits.  The stable
fix patches for earlier kernels will be posted later manually.

bcd96557bd ALSA: hda - Build PCMs and controls at codec driver probe
This makes the code flow easier -- instead of the controller driver
calling snd_hda_build_pcms() and snd_hda_build_controls() explicitly,
the codec driver itself builds PCMs and controls at probe time.  Then
the controller driver only needs to call snd_card_register().

Also, this allows us the full bind/unbind control, too.  Even when a
codec driver is bound later, it automatically registers the new PCM
and controls by itself.
