The firmware extended data IPC and manifest structures are designed to
be extendable without breaking the driver-firmware ABI. Driver should
not raise a warning in case a new header type is detected at
firmware boot. There are already checks for IPC ABI compatibility in
snd_sof_ipc_valid() and if the versions are deemed compatible, extra
fields in IPC messages should not trigger warnings.

We can choose to drop away any length of data from the beginning according
to project needs. Some projects don't want to throw away any data, because
they want to use recorded data to do echo cancellation, so they have to
make sure that they are aligned with the reference data as much as
possible. Or there are other algorithms in the upper layer to eliminate
this noise. Or some projects want to eliminate this noise form the kernel
layer. However, the minimum recommended value is 50ms to skip pop noise.

This series is a prepraration for using generic graph driver for Tegra210
audio. Tegra audio graph series will be sent in a separate series because
it has some dependency over other series for documentation work. This
series can focus on the generic ASoC driver updates. Below are the summary
of changes done.

 * Support multiple instances of a component. For example there can be
   multiple I2S devices which can use the same component driver.

 * Support open platforms with empty Codec endpoint. Customers can plug
   their own HW and can populate codec endpoint.

 * In a component model there can be many components which can be
   connected together. In such cases Identify no-pcm DPCM DAI links which
   can be used in BE<->BE connections.

 * Expose structures or helpers to be re-used by other similar graph
   drivers.

The series is based on following references where DPCM usgae for Tegra
Audio and simple-card driver proposal were discussed.

 * https://lkml.org/lkml/2020/4/30/519 (DPCM for Tegra)
 * https://lkml.org/lkml/2020/6/27/4 (simple-card driver)

Changelog
=========

v4 -> v5
--------
 * No changes in the core/audio-graph driver patches which are
   part of the current series.
 * Dropped Tegra audio patches and doc patches. This will be
   sent separately once the doc depdendencies are resolved.

v3 -> v4
--------
 * Added new patches to convert graph.txt and audio-graph-card.txt
   to corresponding json-schema files. Later these references
   are used in Tegra audio graph schema.

 * AHUB component binding docs are updated to reflect the usage
   of ports/port/endpoint

 * More common stuff is moved into graph_parse_of() and this is
   used by both generic and Tegra audio graph.

 * DT binding for Tegra audio graph is updated to included "ports { }"

 * As per the suggestion 'void *data' member is dropped from
   'asoc_simple_priv' and instead container method is used to
   maintain required custom data internal to Tegra audio graph.

v2 -> v3
--------
 * Dropped new compatible addition in generic graph driver
   after reviewing it with Morimoto-san. Instead added Tegra
   audio graph driver and new compatibles are added in the same.
 * Added new patches to expose new members for customization
   in audio graph driver.
 * Added new patch for Tegra audio graph driver and related
   documentation.
 * Minor change in below commit where mutex version of helper is used
   "ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM"
 * DT binding is updated to use the newly exposed compatibles
 * No changes in other patches

v1 -> v2
--------
 * Re-organized ports/endpoints description for ADMAIF and XBAR.
   Updated DT patches accordingly.
 * After above change, multiple Codec endpoint support is not
   required and hence dropped for now. This will be considered
   separately if at all required in future.
 * Re-ordered patches in the series.

2.7.4

There are two issues in this function.

1) We can't drop the refrences on "cpu", "codec" and "platform" before
   we take the reference.  This doesn't cause a problem on the first
   iteration because those pointers start as NULL so the of_node_put()
   is a no-op.  But on the subsequent iterations, it will lead to a use
   after free.

2) If the devm_kzalloc() allocation failed then the code returned
   directly instead of cleaning up.

This commit exposes following functions which can be used by a sound
card driver based on generic audio graph driver. Idea is vendors can
have a thin driver and re-use common stuff from audio graph driver.

 - graph_card_probe()
 - graph_parse_of()

In doing so a new header file is added for above. The graph_probe()
function is simplified by moving more common stuff to graph_parse_of().

Add new members in struct 'asoc_simple_priv'. Idea is to leverage
simple or graph card driver as much as possible and vendor can
maintain a thin driver to control the behavior by populating these
newly exposed members.

Following are the members added in 'asoc_simple_priv':

  - 'ops' struct: In some cases SoC vendor drivers may want to
    implement 'snd_soc_ops' callbacks differently. In such cases
    custom callbacks would be used.

  - 'force_dpcm' flag: Right now simple or graph card drivers
    detect DAI links as DPCM links if:

      * The dpcm_selectable is set AND
      * Codec is connected to multiple CPU endpoints or aconvert
        property is used for rate/channels.

    So there is no way to directly specify usage of DPCM alone. So a
    flag is exposed to mark all links as DPCM. Vendor driver can
    set this if required.

  - 'dpcm_selectable': Currently simple or audio graph drivers
    provide a way to enable this for specific compatibles. However
    vendor driver may want to define some additional info. Thus
    expose this variable where vendor drivers can set this if
    required.

Audio graph driver is updated to consider above flags or callbacks.
Subsequent patches in the series illustrate usage for above.

For open platforms, which can support pluggable audio cards, Codec
endpoint is not fixed always. It actually depends on the compatible
HW module that is going to be connected. From SoC side the given I/O
interface is always available. Hence such links have fixed CPU endpoint
but no Codec endpoint. This patch helps to support such links where
user can populate Codec endpoint only and its fields in Platform DT
depending on the plugged HW.

PCM devices are created for FE dai links with 'no-pcm' flag as '0'.
Such DAI links have CPU component which implement either pcm_construct()
or pcm_new() at component or dai level respectively. Based on this,
current patch exposes a helper function to identify such components
and populate 'no_pcm' flag for DPCM DAI link.

This helps to have BE<->BE component links where PCM devices need
not be created for CPU component involved in such links.

For multiple instances of components, using DAI name alone for DAI links
is causing conflicts. Components can define multiple DAIs and hence using

The "prefix" can be defined in DAI link node or it can be specified as
part of the component node itself. Currently "sound-name-prefix" defined
in a component is not taking effect. Actually the property is not getting
parsed. It can be fixed by parsing "sound-name-prefix" property whenever
"prefix" is missing in DAI link Codec node.

Merge series "ASoC: ti: davinci-mcasp: Handle incomplete DT node gracefully" from Peter Ujfalusi <peter.ujfalusi@ti.com>:

Hi,

The series is inspired by the effort to standardize TI's arm64 dtsi files to keep
all nodes in 'okay' state and let the board dts files disable not needed
peripherals (and not properly configured):
https://lore.kernel.org/lkml/20201104224356.18040-1-nm@ti.com/

In the unlikely (or likely?) event when the dts misses to disable the McASP node
which is not configured we currenly and luckily just manage to not crash as we
had fixup code in place for legacy pdata boots.
This however prints out a message which does not really help to identify the
issue.

This series will reduce some of the noise during boot (first patch) then
adds the needed changes to handle the variations of 'okay':
A - have all required DT properties for audio
B - gpiochip is enabled

A && !B  -> everything is OK for audio, no gpiochip registered
A && B   -> everything is OK for audio, gpiochip is registered
!A && B  -> audio is not OK, gpiochip is registered. dev_dbg() for audio and do
            not register SOC DAI and PCM
!A && !B ->  audio is not OK, no gpiochip. dev_err() and fail the probe

Regards,

platform_get_irq() would print error message internally, so dev_err()
after platform_get_irq() is not needed

McASP needs three required properties to be usable for audio:
op-mode, tdm-slots and the serial-dir array.

Instead of probing the driver even without the needed information we should
make sure that all the parameters are provided for operation.

The fact that McASP can act as a GPIO controller for it's pins complicates
this a bit, but as a general rule we can:
- we fail the probe if McASP is not configured to be used as gpiochip
- we will not register the DAI (and PCM) if gpiochip is defined

Replace the davinci_mcasp_set_pdata_from_of() function which returned a
pdata pointer with davinci_mcasp_get_config() to return an actual error
code and handle all pdata validation and private mcasp struct setup in
there.

Drop the unused ram-size-playback and sram-size-capture query from DT at
the same time.

The legacy dma_request (which was holding the DMA request number) is no
longer in use for a long time.
All legacy platforms has been converted to dma_slave_map.

Remove it along with the DT parsing to get tx_dma_channel and
rx_dma_channel.
