The time to suspend a single codec may be several hundreds of ms. When runtime
power saving is disabled, driver suspend time can be long especially when there
are more than one codec on the bus.

To reduce driver suspend time, this patch creates a work queue for the bus, and
suspends the codecs in parallel if there are multiple codecs on the bus.

According to Mengdong, we shouldn't enable runtime PM when a codec
doesn't support EPSS, based on the experiences on Windows.
We have already this check in HDMI codec drivers, but now apply it in
general in hda_codec.c.

No functional change.

- codec->pm_down_notified flag is renamed to codec->pm_up_notified
  flag (and takes the reversed meaning), which is managed solely in
  hda_call_pm_notify() now.

- The explicit call of hda_call_pm_notify() is moved into
  hda_keep_power_on().

- Removed a redundant call of hda_call_pm_notify() in
  snd_hda_power_up(), as it's called in hda_call_codec_resume()
  anyway.

If a codec contains only the digital outputs, it's very likely a
HDMI/DP codec, which isn't supported by the generic parser but via
HDMI codec parser code.  Detect such a case and bind with the proper
parser object if available.

Drop the hard dependency on the generic parser code and load / unload
the generic parser code dynamically if built as a module.  This allows
us to avoid the generic parser if only HDMI/DP codecs are found.

Use bus->power_keep_link_on instead.  The controller shouldn't go to
D3 when the link isn't reset, so essentially avoiding the link reset
means avoiding the runtime PM.

This commit fix out of specification about the value of FDF field in out packet
with 'no data'. This affects blocking mode.

According to IEC 61883-6, there is two way to generate AMDTP packets include no
data in blocking mode.

Way 1. an empty packet defined in IEC 61883-1
 - Size of packet is 2 quadlets.
 - The value of FDF is sfc.
 - The packet includes only CIP headers

Way 2. a special non-empty packet defined in IEC 61883-6
 - Size of packet is following to blocking mode
 - The value of FDF is 0xff. This value is 'NO-DATA'. This means 'The receiver'
   must ignore all the data in a CIP with this FDF code'.
 - The packet includes dummy data.

But current implementation is a combination of them.
 - Size of packet is 2 (way 1)
 - FDF = 0xff (way 2)
This causes BeBoB chipset cannot sound.

This patch applies Way 1.

The laptop has a built-in speaker on NID 0x1a.  It's an LFE only on

There might be other surround speakers, but they can fixed in addition

When a codec is resumed, it keeps the power on while the resuming
phase via hda_keep_power_on(), then turns down via
snd_hda_power_down().  At that point, snd_hda_power_down() notifies
the power down to the controller, and this may confuse the refcount if
the codec was already powered up before the resume.

In the end result, the controller goes to runtime suspend even before
the codec is kicked off to the power save, and the communication
stalls happens.

The fix is to add the power-up notification together with
hda_keep_power_on(), and clears the flag appropriately.

The recent change in sysfs triggered a kernel WARNING at unloading a
sound driver like

  WARNING: CPU: 3 PID: 2247 at fs/sysfs/group.c:214 sysfs_remove_group+0xe8/0xf0()
  sysfs group ffffffff81ab7b20 not found for kobject 'event14'

for each jack instance.  It's because the unregistration of jack input
device is done in dev_free callback, which is called after
snd_card_disconnect().  Since device_unregister(card->card_dev) is
called in snd_card_disconnect(), the whole sysfs entries belonging to
card->card_dev have been already removed recursively.  Thus this
results in a warning as input_unregister_device() yet tries to
unregister the already removed sysfs entry.

For fixing this mess, we need to unregister the jack input device at
dev_disconnect callback so that it's called before unregistering the
card->card_dev.

Unbalanced calls to snd_imx_pcm_trigger() may result in endless
FIQ activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the fiq_enable counter to increase and never return to zero again,
so eventually imx_pcm_fiq is never disabled.

Simply removing the fiq_enable will solve the problem, as long as
one never goes play and capture game simultaneously, but beware
trying both at once, the early TRIGGER_STOP will cut off the other
activity prematurely. So now playing and capturing is scrutinized
separately, instead of by counting.

snd_hda_codec_reset() is called either in resetting the whole setup at
error paths or hwdep clear/reconfig sysfs triggers.  But all of these
don't assume that the power has to be off, rather they want to keep
the power state unchanged (e.g. reconfig_codec() calls the power
up/down by itself).  Thus, unconditionally clearing the power state in
snd_hda_codec_reset() leads to the inconsistency, confuses the further
operation.   This patch gets rid of the lines doing that bad thing.
