Takashi Iwai e2dc7d7d8e ALSA: hda - Move audio component accesses to hdac_i915.c
A couple of i915_audio_component ops have been added and accessed
directly from patch_hdmi.c.  Ideally all these should be factored out
into hdac_i915.c.

This patch does it, adds two new helper functions for setting N/CTS
and fetching ELD bytes.  One bonus is that the hackish widget vs port
mapping is also moved to hdac_i915.c, so that it can be fixed /
enhanced more cleanly.

Mengdong Lin d6f220ea13 ASoC: Define add/remove_dai_link ops for a soc card
A machine driver can register the two ops.

When a DAI link is added or removed by a component's topology, the
ASoC core can call the ops to notify the machine driver for extra
intialization or destruction.

E.g. topology can create FE DAI links from a cpu DAI component, and
the machine driver may define an add_dai_link ops to set machine-specific
.init ops for the DAI link.

Mengdong Lin f8f80361d0 ASoC: Implement DAI links in a list & define API to add/remove a link
Implement a dai link list for the soc card.

Add APIs to add/remove a DAI links dynamically, e.g. by topology.

And a dobj is embedded into the struct snd_soc_dai_link. Topology can
use the dobj to find the links created by it and remove them when the
topology component is unloaded.

The predefined DAI links are reserved to keep backward compatibility.
And they will also be added to the list.

Mengdong Lin 1a497983a5 ASoC: Change the PCM runtime array to a list
Currently the number of DAI links is statically defined by the machine
driver at build time using an array. This makes it difficult to shrink/
grow the number of DAI links at runtime in order to reflect any changes
in topology.

We can change the DAI link array in the core to a list so that PCMs and
FE DAI links can be added and deleted at runtime to reflect changes in
use case and DSP topology. The machine driver can still register DAI links
as an array.

As the 1st step, this patch change the PCM runtime array to a list. A new
PCM runtime is added to the list when a DAI link is bound successfully.

Later patches will further implement the DAI link list.

More:
- define snd_soc_new/free_pcm_runtime() to create/free a runtime.
- define soc_add_pcm_runtime() to add a runtime to the rtd list.
- define soc_remove_pcm_runtimes() to clean up the runtime list.

- traverse the rtd list to probe the link components and dais.

- Add a field "num" to PCM runtime struct, used to specify the device
  number when creating the pcm device, and for a soc card to access
  its dai_props array.

- The following 3rd party machine/platform drivers iterate the rtd list
  to check the runtimes:
  sound/soc/intel/atom/sst-mfld-platform-pcm.c
  sound/soc/intel/boards/cht_bsw_rt5645.c
  sound/soc/intel/boards/cht_bsw_rt5672.c

Currently there is no clear definition of what FSYNC polarity is.
Different drivers use its own definition of what is "normal" and what is
"inverted" fsync. This leads to compatibility problems between drivers.

For example TegraX1 driver assumes that DSP-A format with frames
starting at rising FSYNC edge has "inverted" polarity,
while RT5677 assumes it is "normal" polarity.

Explicitly specify meaning of BCLK/FSYNC polarity to avoid future
compatibility problems.

Lars-Peter Clausen bc1043cdcd ALSA: Add helper function to add single value constraint
The recommended and most efficient way to constraint a configuration
parameter to a single value is to set the minimum and maximum allowed
values to the same value, i.e. calling snd_pcm_hw_constraint_minmax() with
the same value for min and max.

It is not necessarily obvious though that this is the approach that should
be taken and some drivers have come up with other ways of solving this
problem, e.g. installing a list constraint with a single item. List
constraints are dynamic constraints though and hence less efficient than
the static min-max constraint.

This patch introduces a new helper function called
snd_pcm_hw_constraint_single() which only takes a single value has the same
effect as calling snd_pcm_hw_constraint_minmax() with the same values for
min and max. But it is hopefully semantically more expressive, making it
clear that this is the preferred way of setting a single value constraint.

Subhransu S. Prusty da23ac1e40 ALSA: hda - Add hduadio support to DEVTABLE
For generating modalias entries automatically, move the definition of
struct hda_device_id to linux/mod_devicetable.h and add the handling
of this record in file2alias helper.  The new modalias is represented
with combination of vendor id, device id, and api version as
"hdaudio:vNrNaN".

This patch itself doesn't convert the existing modaliases.  Since they
were added manually, this patch won't give any regression by itself at
this point.

[Modified the modalias format to adapt the api_version field, and drop
 invalid ANY_ID definition by tiwai]

Takashi Iwai 93ed8560e9 ALSA: hda - Add api_version to hda_device_id struct
For distinguishing the difference between HDA legacy and ext codec
driver entries, we need to expose the value corresponding to type
field.  This patch adds a new field, api_version, to hda_device_id
struct, so that this information is embedded in modalias string.

Although the information is basically redundant (struct hdac_device
already has type field), the helper that extracts from
MODULE_DEVICE_TABLE() won't take it account except for the exported
table entries themselves.  So we need to put the same information in
the table, too.

Charles Keepax 34198710f5 ASoC: Add info callback for SX_TLV controls
SX_TLV controls are intended for situations where the register behind
the control has some non-zero value indicating the minimum gain
and then gains increasing from there and eventually overflowing through
zero.

Currently every CODEC implementing these controls specifies the minimum
as the non-zero value for the minimum and the maximum as the number of
gain settings available.

This means when the info callback subtracts the minimum value from the
maximum value to calculate the number of gain levels available it is
actually under reporting the available levels. This patch fixes this
issue by adding a new snd_soc_info_volsw_sx callback that does not
subtract the minimum value.

This structure was added by 4d96eb255c ('ALSA: pcm_lib - add possibility
to log last 10 DMA ring buffer positions') to store PCM pointers
information of latest 10 pointer movements (=XRUN_LOG_CNT). When
CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has
'hwptr_log' member with a pointer to the structure. When calling
xrun_log() in pcm_lib.c, the structure was allocated to the pointer.
When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer
is released.

In f5914908a5 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'),
the pointer logging is replaced with using Linux Kernel Tracepoints. The
structure was also removed, while it's just declared. The member and kfree
still remains.

This commit removes the member and related codes. I think this was
overlooked because it brings no errors/warnings to C compilers.

Vinod Koul ee2d51b3d4 ALSA: hdac: Add API for removing hdac extended device
The HDAC extended device objects are created by HDAC extended bus on probe.
When controller is removed they should be removed as well, so add API
snd_hdac_ext_bus_device_remove for this

Mark Brown 78b50f3914 ASoC: topology: Add Kconfig option for topology
Allow the topology code to be compiled out so that users who don't need
topology don't need to havve the code compiled in, saving them some
memory.

Some more configuration could be added to remove some of the hooks into
the core data structures but that is probably best done with some
refactoring to use functions to do the updates of the data structures
rather than ifdefing in the code as we'd need to do at the minute.

Lars-Peter Clausen a3423b02cf ASoC: dapm: Consolidate input and output path handling
After the recent cleanups and generalizations of the DAPM algorithm the
handling of input and output paths is now fully symmetric. This means by
making some slight changes to the data structure and using arrays with one
entry for each direction, rather than separate fields, it is possible to
create a generic implementation that is capable of handling both input and
output paths.

Unfortunately this generalization significantly increases the code size on
the hot path of is_connected_{input,output}_ep() and
dapm_widget_invalidate_{input,output}_paths(), which has a negative impact
on the overall performance. The inner loops of those functions are quite
small and the generic implementation adds extra pointer arithmetic in a few
places.

Testing on ARM shows that the combined code size of the specialized
functions is about 50% larger than the generalized function in relative
numbers. But in absolute numbers its less than 200 bytes, which is still
quite small. On the other hand the generalized function increases the
execution time of dapm_power_one_widget() by 30%. Given that this function
is one of the most often called functions of the DAPM framework the
trade-off of getting better performance at expense of generating slightly
larger code at seems to be worth it.

To avoid this still keep two versions of these functions around, one for
input and one for output. But have a generic implementation of the
algorithm which gets inlined by those two versions. And then let the
compiler take care of optimizing it and removing he extra instructions.

This still reduces the source code size as well as the makes making changes
to the implementation more straight forward since the same change does no
longer need to be done in two separate places. Also on the slow paths we
can use a generic implementations that handle both input and output paths.

Lars-Peter Clausen e63bfd45ab ASoC: dapm: Add widget path iterators
Add helper iterator macros for iterating over the source and sink paths of
widget. This will make it easier to change the implementation later on.

Lars-Peter Clausen 7361fbeaea ASoC: ac97: Add support for resetting device before registration
AC97 devices need to be initially reset before they can be used. Currently
each driver does this on its own.

Add support for resetting the device to core in snd_soc_new_ac97_codec().
If the caller supplies a device ID and device ID mask the function will
reset the device and verify that it has the correct ID, if it does not a
error is returned.

This will allow to remove custom code with similar functionality from
individual drivers.

Lars-Peter Clausen 5f1d980ee9 ALSA: ac97: Add helper function to reset the AC97 device
There is currently a lot of code duplication in ASoC drivers regarding the
reset handling of devices. This patch introduces a new generic reset
function in the generic AC'97 framework that can be used to replace most
the custom reset functions.
