The drain and drain_notify callback were blocked by low level driver
until the draining was complete. Due to this being invoked with big
fat mutex held, others ops like reading timestamp, calling pause, drop
were blocked.

So to fix this we add a new snd_compr_drain_notify() API. This would
be required to be invoked by low level driver when drain or partial
drain has been completed by the DSP. Thus we make the drain and
partial_drain callback as non blocking and driver returns immediately
after notifying DSP.  The waiting is done while releasing the lock so
that other ops can go ahead.

This machine has a mute LED as well as a noisy internal mic. Hence it needs

Some HP machines with Realtek codecs have mute LEDs connected to VREF pins.
However when these go into runtime suspend, the pin powers down and its
pin control is disabled, thus disabling the LED too.

This patch fixes that issue by making sure that the pin stays in D0 with
correct pin control.

"HDA Intel MID" is no correct name for Haswell HDMI controllers.

Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Haswell HDMI audio controllers seem to get stuck when unaligned buffer
size is used.  Let's enable the buffer alignment for the corresponding
entries.

Since AZX_DCAPS_INTEL_PCH contains AZX_DCAPS_BUFSIZE that disables the
buffer alignment forcibly, define AZX_DCAPS_INTEL_HASWELL and put the
necessary AZX_DCAPS bits there.

The device IDs of the AMD Cypress/Juniper/Redwood/Cedar/Cayman/Antilles/
Barts/Turks/Caicos HDMI HDA controllers weren't added explicitly
because the generic entry works, but it made the device appearing as
"Generic", and people are confused as if it's no proper HDMI

instead of "Generic".

work fine without disabling snooping.

Add a bitmask to hda_gen_spec indicating NIDs to exclude from the
possible volume controls.  That is, when the bit is set, the NID
corresponding to the bit won't be picked as an output volume control
any longer.

Basically this is just a band-aid for working around the issue found
with CS4208 codec, where only the headphone pin has a volume AMP with
different dB steps.

If wChannelconfig is given for some formats but not others, userspace
might not be able to set the channel map.

This is RFC because I'm not sure what the best behaviour is - to guess
the channel map from the given number of channels (it's quite likely
that one channel is MONO and two channels is FL FR), or just to supply
UNKNOWN for all channels.

But the complete lack of channel map for a format leads userspace to
believe that the format is not available at all. Or am I
misunderstanding how this should be used?

NVIDIA HDMI codecs do not seem to follow the Audio Sample Packet (ASP)
channel mapping (as set by verb F32h per HDA specification 7.3.3.41)
when playing back 2-channel audio (CEA CA 0x00).

Basically this means that specifying swapped channels for stereo audio
(FR,FL) does not take effect, and e.g. this command plays back on the
wrong channel:
speaker-test -c2 -Dhdmi:CARD=NVidia,DEV=0 -m FR,FL -s1

Multichannel audio is not affected.

This issue has been confirmed to exist on codec 0x10de0015 by me and on
0x10de0040 by Juho Teperi.

Disable 2ch FL/FR channel swapping on all NVIDIA HDMI codecs that use
the standard HDA channel mapping system. Since this is a very minor
functionality loss, we err on the side of disabling it for newer codecs
as well until any future testing confirms that this issue has been
fixed.
