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
 
 Misc:
 - ice1724: Improved ESI W192M support
 - emu10k1: Emu 1010 fixes/enhancement

Kuninori Morimoto a5053a8e20 ASoC: core: call snd_soc_runtime_set_dai_fmt() before soc_new_pcm()
Current snd_soc_runtime_set_dai_fmt() is called after
soc_probe_link_dais(). this means snd_soc_dai_set_fmt() will be
called after soc_new_pcm().

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.

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

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.

Lars-Peter Clausen 86d7500326 ASoC: dapm: Simplify fully route card handling
For legacy reasons the ASoC framework assumes that a CODEC INPUT or OUTPUT
widget that is not explicitly connected to a external source or sink is
potentially connected to a source or a sink and hence the framework treats
the widget itself as source (for INPUT) or sink (for OUTPUT). For this
reason a INPUT or OUTPUT widget that is really not connected needs to be
explicitly marked as so.

Setting the card's fully_routed flag will cause the ASoC core, once that all
widgets and routes have been registered, to go through the list of all
widgets and mark all INPUT and OUTPUT that are not externally connected as
non-connected. This essentially negates the default behaviour of treating
INPUT or OUTPUT widgets without external routes as sources or sinks.

This patch takes a different approach while getting the same result. Instead
of first marking INPUT and OUTPUT widgets as sinks/sources and then later
marking them as non-connected, just never mark them as a sink or a source if
the fully_routed flag is set on a card.

This requires a lot less code and also results in a slightly faster card
initialization since there is no need to iterate over all widgets and check
whether the INPUT and OUTPUT widgets are connected or not.

If regmap is disabled there will be no users of the ASoC regmap helpers.
Furthermore regmap_exit() will no be defined causing the following compile
error:

Lars-Peter Clausen 20feb88198 ASoC: Add helper functions for deferred regmap setup
Some drivers (most notably the AC'97 drivers) do not have access to their
regmap struct when the component/codec is registered. For those drivers the
automatic regmap setup will not work and needs to be done manually,
typically from the component/CODEC drivers probe callback.

This patch adds a set of helper function to handle deferred regmap
initialization as well as early regmap tear-down.

Lars-Peter Clausen bc26321404 ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_control
Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.

While we are at it also change the type from int to bool.

The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>
@@
identifier drv;
@@
struct snd_soc_dai_driver drv = {
-	.ac97_control
+	.bus_control
	=
-	1
+	true
};
// </smpl>

Lars-Peter Clausen 6794f709b7 ASoC: ac97: Drop delayed device registration
We have all the information and dependencies we need to initialize and
register the device available in snd_soc_new_ac97_codec(). So there is no
need to delay the device registration until after the card itself as been
registered.

This makes the code significantly simpler and also makes it possible to use
the AC'97 device in the CODECs probe function. The later will be required to
be able to convert the AC'97 CODEC drivers to regmap.

This has no users since commit f0fba2ad1b ("ASoC: multi-component - ASoC
Multi-Component Support") which was almost 5 years ago. Given that this runs
after CODEC probe functions have been run it also doesn't seem to be that
useful.

So drop it altogether to make the code simpler.

Currently the AC'97 support is splattered all throughout soc-core.c. Some
parts are #ifdef'd some parts are not. This patch moves the AC'97 support to
its own file, this should make the code a bit more clearer and also makes it
possible to easily not compile it into the kernel when not needed.

Lars-Peter Clausen 70f3af3ca1 ASoC: Properly handle AC'97 device lifetime management
The memory that a struct device is contained in must not be freed except
from within the device's release callback. The ASoC code currently does not
adhere to this rule for the AC'97 device. This patch fixes it by moving the
freeing of the AC'97 to the release callback and splitting up the
registration and unregistration of the device into separate steps for
getting/putting the reference to the device and adding/removing it to the
device hierarchy.
