Added pte offset variable in audio_substream_data structure.
Added Stoney related PTE offset macros in acp header file.
Modified hw_params callback to assign the pte offset value
based on asic_type.
PTE Offset macros used to calculate no of PTE entries
need to be programmed when memory allocated for audio buffer.
Depending upon allocated audio buffer size, PTE offset values
will change.
Compared to CZ, Stoney has SRAM memory limitation i.e 48k
It is required to define separate PTE Offset macros for
Stoney.

This patch adds support to Q6AFE (Audio Front End) module on Q6DSP.
AFE module sits right at the other end of cpu where the codec/audio
devices are connected.
AFE provides abstraced interfaces to both hardware and virtual devices.
Each AFE tx/rx port can be configured to connect to one of the hardware
devices like codec, hdmi, slimbus, i2s and so on. AFE services include
starting, stopping, and if needed, any configurations of the ports.

TC Electronic Digital Konnekt x32 is an application of WaveFront DiceII STD
and doesn't support TCAT extended application protocol. For such devices,
ALSA dice driver needs to have hard-coded parameters for stream formats.
This commit adds stream format parameters for this model. Unfortunately, at
sampling transmission frequencies of 88.2/96.0kHz, I confirmed that current
ALSA dice driver doesn't drive the device appropriately due to detecting
packet discontinuities.
$ journalctl
kernel: snd_dice fw1.0: Detect discontinuity of CIP: 90 80
At the frequencies, the device transfers 16 data blocks per packet and 16
data channels per data block, as a result one packet includes 1032 bytes
if it's not NODATA. However, as long as I checked, the device often
postpone packet transmission and continue with truncated payload than
metadata in isochronous packet header. Below is a sample of sequence I got.

I cannot confirm this quirks with Windows driver. ALSA dice driver has a
cause if assumed differences between these two drivers are ways of
timestampling to RX packets from the drivers to the device. I've already
reported timestamping quirk of Dice-based devices and this might bring
this issue.

This may brings inconvenience to users but I expect developers and users

There are still many places calling the timer's hw.c_resolution
callback without lock, and this may lead to some races, as we faced in
the commit a820ccbe21e8 ("ALSA: pcm: Fix UAF at PCM release via PCM
timer access").
This patch changes snd_timer_resolution() to take the timer->lock for
avoiding the races. A place calling this function already inside the
lock (from the notifier) is replaced with the
snd_timer_hw_resolution() accordingly, as well as wrapping with the
lock around another place calling snd_timer_hw_resolution(), too.

Instead of open-coding for getting the timer resolution, use the
standard snd_timer_resolution() helper.
The original code falls back to the callback function when the
resolution is zero, but it must be always so when the callback
function is defined. So this should be no functional change.

Many X86 devices using a BYT SoC + RT5640 codec are cheap devices with
generic DMI strings, causing snd_soc_set_dmi_name() to fail to set a
long_name, making it impossible for userspace to have a correct UCM
profile which only uses inputs / outputs which are actually hooked up
on the device.
Our quirks already specify which input the internal mic is connected to
and if a single (mono) speaker is used or if the device has stereo
speakers.
This commit sets a long_name based on the quirks so that userspace can
have UCM profiles doing the right thing based on the long_name.
Note that if we ever encounter the need for a special UCM profile for
some device we can add a quirk to set a specific long_name for the
device,

Even with our recently tweaked defaults, quite a few bytcr_rt5640 devices
still need quirks to be fully functional. This commits adds quirks where
necessary for the 16 bytcr_rt5640 devices I have access to.
The quirks are added for the following reasons:
1) Devices with only one speaker need the mono quirk to avoid driving an
unused and potentially short-circuited output. 8 of my sample of 16 devs
are mono, 4 of these would work with the defaults if it were not for their
mono speaker.
2) Devices using a different input for the internal mic then the default,
this is the case for 6 of my sample of 16 devices.
3) BYTCR devices without an ACPI channel map, which do not work with the
default of SSP0-AIF2, this is the case for 2 of my sample of 16 devices.
4) Devices which need non-default jack-detect settings, this is the case
for 6 of my sample of 16 devices.

Currently we've 2 places with BYTCR defaults: 1. The generic catch-all
DMI_SYS_VENDOR=="Insyde" DMI quirk which selects SSP0-AIF1 for generic
Insyde BYTCR tablets without the ACPI channel package; and 2. the
defaults in the if (is_bytcr) {} code block.
Currently these are not identical, both select IN3 as the internal mic
output, but the "Insyde" DMI quirk leaves out the DIFF_MIC quirk. The
DIFF_MIC quirk should be enabled by default, because enabling diff. input
helps a lot for devices with a differential mic, where as it is a nop on
devices with a normal mic.
This commit adds the DIFF_MIC quirk to the "Insyde" DMI quirk path, by
adding a new BYTCR_INPUT_DEFAULTS define and using that in both code paths
which set BYTCR defaults.
Having a single place where the BYTCR input defaults are defined also
allows defining jack-detect defaults in a single place in a follow-up
commit.

Out of the 11 BYTCR devices which I have access to for testing,
7 use IN3 for the internal mic and only 1 uses IN1 for the internal mic,
the other 3 use DMIC1.
So IN3 clearly is a better default, using IN3 as default avoids the need
to add DMI quirks for some of these devices.

This fixes the following 3 issues:
1) The sys_vendor match should be for "Dell Inc." not "DellInc.",
without this fixed the quirk never gets applied
2) DMIC1 is used not DMIC2, this was not a problem sofar because for
regular BYT boards (rather then BYTCR) we default to DMIC1 and because
of 1. the quirk was not being applied
3) The Dell Venue 8 5830 Pro only has a single speaker

Use device-properties for setting up the dmic, based on the
BYT_RT5640_MAP() value, instead of using the codec specific
rt5640_dmic_enable() function for this. This also removes the need
for the BYT_RT5640_DMIC_EN quirk, which was always set together with
a MAP() quirk of DMIC1_MAP or DMIC2_MAP.

The commit 289ca025ee1d ("ALSA: Use priority list for managing device
list") changed the way to register/disconnect/free devices via a
single priority list. This helped to make behavior consistent, but it
also changed a slight behavior change: namely, the control device is
registered earlier than others, while it was supposed to be the very
last one.
I've put SNDRV_DEV_CONTROL in the current position as the release of
ctl elements often conflict with the private ctl elements some PCM or
other components may create, which often leads to a double-free.
But, the order of register and disconnect should be indeed fixed as
expected in the early days: the control device gets registered at
last, and disconnected at first.
This patch changes the priority list order to move SNDRV_DEV_CONTROL
as the last guy to assure the register / disconnect order. Meanwhile,
for keeping the messy resource release order, manually treat the
control and lowlevel devices as last freed one.
Additional note:
The lowlevel device is the device where a card driver creates at
probe. And, we still keep the release order control -> lowlevel, as
there might be link from a control element back to a lowlevel object.

The sdma-pcm does not need any information from omap-dma.h, it only needs
to include the omap-dmaengine.h - for the omap_dma_filter_fn, but that
might not be needed at all as OMAP1 was converted to dma_slave_map, but
I can not test OMAP1.
Add the linux/device.h include as well for devm_kzalloc()

retire_capture_urb() may print warning messages when the given URB
doesn't align, and this may flood the system log easily.
Put the rate limit to the message for avoiding it.

Implement essential initialization of the sound driver:
- introduce required data structures
- handle driver registration
- handle sound card registration
- register sound driver on backend connection
- remove sound driver on backend disconnect
Initialize virtual sound card with streams according to the
Xen store configuration.
Implement ALSA driver operations including:
- manage frontend/backend shared buffers
- manage Xen bus event channel states
Implement requests from front to back for ALSA
PCM operations.
- report ALSA period elapsed event: handle XENSND_EVT_CUR_POS
notifications from the backend when stream position advances
during playback/capture. The event carries a value of how
many octets were played/captured at the time of the event.
- implement explicit stream parameter negotiation between
backend and frontend: handle XENSND_OP_HW_PARAM_QUERY request
to read/update configuration space for the parameter given:
request passes desired parameter interval and the response to
this request returns min/max interval for the parameter to be used.
