o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

28ed125b9a ALSA: x86: Avoid register accesses during disconnection
It seems that accessing registers during disconnection often leads to
the GPU pipe error.  The original driver had a similar check in the
past, but it was lost through refactoring.  Now put a connection check
in the register access functions.

One exception is the irq handler: it still needs to access the raw
register even while disconnected, because it has to read and write to
ACK the irq mask.  Although the irq shouldn't be raised while
disconnected (the stream should have been disabled), let's make it
safer for now.

e2acecf2c8 ALSA: x86: Handle reset at prepare callback
Currently the driver handles some reset procedure at the trigger STOP
and the underrun functions, where both are executed in the interrupt
context.  Especially the underrun function has a sync-loop to clear
the UNDERRUN status bit, and this is supposed to be one of plausible
causes of GPU hangup.

Since the job to be done in the interrupt handler should be minimum,
we move the reset function out of trigger and underrun, and push it
into the prepare (and hw_free) callbacks instead.  Here a new flag,
need_reset, is introduced to indicate the requirement of the reset
procedure.  This is for avoiding the multiple resets when PCM prepare
is called sequentially.

Also in the UNDERRUN bit-clear sync loop, take a longer pause to be in
the safer side.  Taking a longer delay is no longer a problem now
because we're running in the normal context.

The PCM engine on LPE audio isn't like a batch-style process any

BATCH info flag so that PA can handle the buffer in timer-sched mode.

Similarly, the DOUBLE flag is also superfluous.  Drop both bits.

had_enable_audio_int() came from the LPE audio shell set_caps

For avoiding the further misunderstanding, rename the function to the

in allover places.  There is no functional changes at all.

warning: (SND_SOC_ALL_CODECS) selects SND_SOC_ES8328_I2C which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_ES8328 && I2C)

This adds the respective Kconfig dependencies and changes SND_SOC_ES8328 to a hidden
symbol that is selected implicitly by the two more specific options, as we do for
some other codecs. We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the

e1b239f371 ALSA: x86: Refactor PCM process engine
This is again a big rewrite of the driver; now it touches the code to
process PCM stream transfers.

The most fundamental change is that the driver may support more than
four periods.  Instead of keeping the same index between both the ring
buffer (with the fixed four buffer descriptors) and the PCM buffer
periods, we keep difference indices for both (bd_head and pcm_head
fields).  In addition, when the periods are more than four, we need to
track both head and next indices.  That is, we now have three indices:
bd_head, pcm_head and pcm_filled.

Also, the driver works better for periods < 4, too: the remaining BDs
out of four are marked as invalid, so that the hardware skips those
BDs in its loop.

By this flexibility, we can use even ALSA-lib dmix plugin, which
requires 16 periods as default.

The buffer size could be up to 20bit, so the max buffer size was
increased accordingly.  However, the buffer pre-allocation is kept as
the old value (600kB) as default.  The reason is the limited number of
BDs: since it doesn't suffice for the useful SG page management that
can fit with the usual page allocator like some other drivers, we have
to still allocate continuous pages, hence we shouldn't take too big
memories there.

f69bd104b5 ALSA: x86: Move stream status into pcm_stream_info
The only remaining field in struct had_stream_data is stream_type that
holds the current stream status.  Such information fits better in
struct pcm_stream_info, so move it as a boolean "running" field to be
clearer.

This allows us to get rid or had_stream_data definition and
references.

Also, the superfluous status check get removed in a couple of places
where we can call PCM helpers in anyway.

182cdf23db ALSA: x86: Implement runtime PM
Although the driver has some PM callbacks, it doesn't do it right:
- the suspend callback doesn't handle to suspend the running PCM,
- the runtime PM ops are missing,
- pm_runtime_get_sync() isn't used at the right place.

This patch covers the above and provides the basic runtime PM

313d9f28c1 ALSA: x86: Properly manage PCM substream lifetype
The PCM substream is referred not only in the PCM callbacks but also
in the irq handler and in the hotplug/unplug codes.  The latter code
paths don't take the PCM lock, thus the PCM may be released
unexpectedly while calling PCM helper functions or accessing
pcm->runtime fields.

This patch implements a simple refcount to assure the PCM substream
accessibility while the other codes are accessing.  It needed some
code refactoring in the relevant functions for avoiding the doubly
spinlocks.

da86480974 ALSA: x86: Flatten two abstraction layers
This is the final stage for a big clean-up series.  Here we flatten
the two layers into one.  Formerly, the implementation was split to
HDMI "shell" that talks with the platform device, and HDMI audio part
that communicates via caps and other event handlers.  All these would
be good if there were multiple instantiations or if there were data
protection.  But neither are true in our case.  That said, it'll be
easier to have a flat driver structure in the end.

In this patch, the former struct hdmi_lpe_audio_ctx is forged into the
existing struct snd_intelhad.  The latter has already a few members
that are basically the copy from the former.  Only a few new members
for the lowlevel I/O are added by this change.

Then, the had_get_caps() and had_set_caps() are simply replaced with
the direct calls to copy the data in the struct fields.  Also, the
had_event_handler() calls are replaced with the direct call for each
event as well.

For reducing the global variable reference, keep snd_intelhad object

for further cleanup.

This also includes the simplification of the probe procedure: the LPE
platform driver directly gets the created snd_intelhad object by
hdmi_audio_probe(), and passes it to each helper and destructor,
hdmi_audio_remove().  The hdmi_audio_probe() function doesn't call the
back-registration any longer, which is fairly useless.  The LPE
platform driver initializes the stuff instead at the right place, and
calls the wq after the object creation in the probe function itself.
