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

We don't always need soc-compress in soc, here add a config item
SND_SOC_COMPRESS, when nobody select it, the soc-compress will
not be compiled.

Here also change Kconfig to 'select SND_SOC_COMPRESS' for drivers

Jyri Sarha 6c84e5917f ASoC: soc-core: Fix sparse warning in be32_to_cpup() call
Store return value of of_get_property() to a pointer of __be32 type as
device tree has big endian type. This fixes a sparse warning couple of
lines later when be32_to_cpup() is used to convert from big endian to
cpu endian.

The whole conversion is not really necessary, as we are only checking
if the value is zero or not, but I wanted to add it to remind in the
future that the data has to be converted before use. Compiler should
optimize the unnecessary operations away.

Lars-Peter Clausen abd31b32dd ASoC: Use card field to indicate whether a component is bound
Use the card field of a component to indicate whether it is bound or not.
This makes a certain sense given that the field contains the card the
component is bound to and a component can only be bound to one card at a
time. And it also requires to unset the card field when the component is
unbound from the card.

This makes the probded flag redundant and it can be removed.

Lars-Peter Clausen 1b7c123169 ASoC: Prevent components from being bound to multiple cards
A component can only be bound to a single card at a time. Binding it to
card while it is already bound to another will result in undefined
behavior.

As the undefined behavior might only manifest itself later on it is not
necessarily always straight forward to find the cause. To prevent this add
a check that refuses to bind a component to multiple cards as well as
prints a error describing the problem.

The core exports some APIs to client drivers in order to load and unload
firmware topology data as use case require.

Currently the core deals with the following object types :-

 o kcontrols. This includes TLV, enumerated and bytes controls.
 o DAPM widgets. All types with any associated kcontrol.
 o DAPM graph.
 o FE PCM. FE PCM capabilities and configuration can be defined.
 o BE DAI Link. BE DAI link capabilities and configuration can be defined.

Srinivas Kandagatla 9e4980896c ASoC: skip legacy dai naming if dai driver has all the information
Original issue is that the id field in the dai is not same as the id
in dai_driver when dai driver count == 1. This is due to the legacy
dai naming check, which could possibly cause issues if the audio drivers
written in assumption that dai->id would be always equal to dai_driver->id.
This assumption is true only if the dai driver count is greater than 1,
and false if dai driver count is 1. On Qcom Lpass driver we hit such
issue while adding support to apq8016.

The code path which falls back to legacy naming for cases where num_dai
== 1 does not check if there is any valid information in the dai_driver.
This patch fixes that by checking if the dai_driver has valid id and
name before falling back to legacy dai naming
Although the drivers can work around this issue by only using
dai->driver->id, but this patch attempts to fix the actual issue.

Linus Torvalds d0a3997c0c sound updates for 4.1-rc1
There have been major modernization with the standard bus: in ALSA
 sequencer core and HD-audio.  Also, HD-audio receives the regmap
 support replacing the in-house cache register cache code.  These
 changes shouldn't impact the existing behavior, but rather
 refactoring.
 
 In addition, HD-audio got the code split to a core library part and
 the "legacy" driver parts.  This is a preliminary work for adapting
 the upcoming ASoC HD-audio driver, and the whole transition is still
 work in progress, likely finished in 4.1.
 
 Along with them, there are many updates in ASoC area as usual, too:
 lots of cleanups, Intel code shuffling, etc.
 
 Here are some highlights:
 
 ALSA core:
 - PCM: the audio timestamp / wallclock enhancement
 - PCM: fixes in DPCM management
 - Fixes / cleanups of user-space control element management
 - Sequencer: modernization using the standard bus
 
 HD-audio:
 - Modernization using the standard bus
 - Regmap support
 - Use standard runtime PM for codec power saving
 - Widget-path based power-saving for IDT, VIA and Realtek codecs
 - Reorganized sysfs entries for each codec object
 - More Dell headset support
 
 ASoC:
 - Move of jack registration to the card level
 - Lots of ASoC cleanups, mainly moving things from the CODEC level
   to the card level
 - Support for DAPM routes specified by both the machine driver and DT
 - Continuing improvements to rcar
 - pcm512x enhacements
 - Intel platforms updates
 - rt5670 updates / fixes
 - New platforms / devices: some non-DSP Qualcomm platforms, Google's
   Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC

Before appling 1efb53a220
(ASoC: simple-card: Remove support for setting differing DAI formats)
simple-card user had (1) snd_soc_dai_set_fmt() -> soc_new_pcm(),
but, after that it is (2) soc_new_pcm() -> snd_soc_dai_set_fmt().
At least rsnd driver is assuming (1) pattern.

This patch move snd_soc_dai_set_fmt() into soc_probe_link_dais()
after the dai_link->init section to solve this issue.

Lars-Peter Clausen 6553bf06a3 ASoC: Don't try to register debugfs entries if the parent does not exist
If the registration of a debugfs directory fails this is treated as a
non-fatal error in ASoC and operation continues as normal. This means we
need to be careful and check if the parent debugfs directory exists if we
try to register a debugfs file or sub-directory. Otherwise we might end up
passing NULL for the parent and the file or directory will be registered in
the top-level debugfs directory.

Kuninori Morimoto 4e2576bd36 ASoC: soc-core: initialize debugfs in snd_soc_instantiate_card()
Current soc_init_card_debugfs() is called from snd_soc_register_card()
but, soc_cleanup_card_debugfs() is called from soc_cleanup_card_resources(),
not from paired function.

This differences don't matter for now. But if anyone wants to implement
a proper hotplug/unplug, this difference would become clearer.

Now, we can assume that snd_soc_instantiate_card() and
soc_cleanup_card_resources() are paired function.
soc_init_card_debugfs() / soc_cleanup_card_debugfs() paired function
should be called from these.

Lars-Peter Clausen 34e81ab455 ASoC: Fix component lists locking
Any access to the component_list, codec_list and platform_list needs to be
properly locked by the client_mutex. Otherwise undefined behavior can occur
if the list is modified in one thread and concurrently accessed from another
thread.

This patch adds the missing locking to the debugfs file handlers that
display the registered components, as well as the various components
unregister functions.

Furthermore the client_lock is now held for the whole
snd_soc_instantiate_card() sequence to make sure that component removal does
not race against the card registration.

The current helper functions, snd_soc_of_parse_audio_simple_widgets()
and snd_soc_of_parse_audio_routing(), set dapm_widgets and dapm_routes
without caring if they are already set by using build-in widgets and
routes in the card driver. So there could be one of them, build-in one
or Device Tree one, overrided by the other depending on which one was
assigned later.

This patch adds an extra pair of dapm_widgets and dapm_routes for DT
use only so as to prevent unexpected overriding.

For some setups it is necessary to change the DAI link format at runtime.
This patch factors out the code that does the initial static DAI link format
configuration into a separate helper function which can be used board
drivers as well.

This allows board drivers that have to change the DAI link format at runtime
to reuse it instead of having to manually change the format on all DAIs.
