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.

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.

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

Theoretically setting the state to SNDRV_PCM_STATE_DISCONNECTED is
correct. But, unfortunately, PA gets confused by this action, and it
won't re-probe the device after HDMI/DP is re-plugged. (It reprobes
only when the card itself is recreated.)
As a workaround, set SNDRV_PCM_STATE_SETUP instead.

Some SoCs have a reset line that must be asserted/deasserted.
This patch adds a quirk to handle the new compatible
"allwinner,sun6i-a31-i2s" which will deassert the reset
line on probe function and assert it on remove's one.
This new compatible is useful in case of A33 codec driver, for example.

When playing a sound for the first time, a short delay, where the audio
file is not played, can be noticed.
On a second play (right after), the sound is played correctly.
If we wait a short time (~5 sec which corresponds to the aplay
timeout), the delay is back.
This patch fixes it by using an event on headphone amplifier.
It allows to keep the amplifier enable while playing a sound.
A delay of 700ms allows to wait that the amplifier is powered-up
before playing the sound.

We can get audio errors if hitting deeper idle states on omaps:
[alsa.c:230] error: Fatal problem with alsa output, error -5.
[audio.c:614] error: Error in writing audio (Input/output error?)!
This seems to happen with off mode idle enabled as power for the
whole SoC may get cut off between filling the McBSP fifo using DMA.
While active DMA blocks deeper idle states in hardware, McBSP
activity does not seem to do so.
Basing the QoS latency calculation on the FIFO size, threshold,
sample rate, and channels.

On Baytrail and Cherrytrail, HDaudio may be fused out or disabled
by the BIOS. This driver enables an alternate path to the i915
display registers and DMA.
Although there is no hardware path between i915 display and LPE/SST
audio clusters, this HDMI capability is referred to in the documentation
as "HDMI LPE Audio" so we keep the name for consistency. There is no
hardware path or control dependencies with the LPE/SST DSP functionality.
The hdmi-lpe-audio driver will be probed when the i915 driver creates
a child platform device.
Since this driver is neither SoC nor PCI, a new x86 folder is added
