Liam Girdwood b8c0dab9bf ASoC: core - PCM mutex per rtd
In preparation for the new ASoC Dynamic PCM support (AKA DSP support).

The new ASoC Dynamic PCM core allows DAIs to be dynamically re-routed
at runtime between the PCM device end (or Frontend - FE) and the physical DAI
(Backend - BE) using regular kcontrols (just like a hardware CODEC routes
audio in the analog domain). The Dynamic PCM core therefore must be
able to call PCM operations for both the Frontend and Backend(s) DAIs at
the same time.

Currently we have a global pcm_mutex that is used to serialise
the ASoC PCM operations. This patch removes the global mutex
and adds a mutex per RTD allowing the PCM operations to be reentrant and
allow control of more than one DAI at at time. e.g. a frontend PCM hw_params()
could configure multiple backend DAI hw_params() with similar or different
hw parameters at the same time.

Liam Girdwood ddee627cf6 ASoC: core - Separate out PCM operations into new file.
In preparation for Dynamic PCM support (AKA DSP support).

There will be future patches that add support to allow PCMs to be dynamically
routed to multiple DAIs at startup and also during stream runtime. This patch
moves the ASoC core PCM operaitions into a new file called soc-pcm.c.  This will
in simplify the ASoC core features into distinct files.

Lars-Peter Clausen 4b80b8c2ee ASoC: snd_soc_new_{mixer,mux,pga} make sure to use right DAPM context
Currently it is possible that snd_soc_new_{mixer,mux,pga} is called with a
DAPM context not matching the widgets context. This can lead to a wrong
prefix_len calculation, which will result in undefined behaviour. To avoid
this always use the DAPM context from the widget itself.

Timur Tabi 147dfe90f7 ASoC: p1022ds: fix incorrect referencing of device tree properties
Device tree integer properties are encoded in big-endian format, but some of
the Freescale ASoC drivers were assuming that the host is in big-endian format
as well.  Although this is true, it's better to use endian-safe accessors.

Also add a check for a failed ioremap() call in the SSI driver.

Timur Tabi 0cd114fff9 ASoC: fsl: fix initialization of DMA buffers
The DMA (PCM) driver used by some Freescale PowerPC supports separate DAIs
for playback and capture, so DMA buffers should be allocated only for the
initialized streams.  Instead of checking for the number of active channels,
which apparently is not reliable, check to see if the actual stream object
exists.

Also provide a better name for the DMA interrupt.

Mark Brown ffdaa48aed ASoC: Suppress restore of default register values for rbtree cache sync
Currently the rbtree code will write out the entire register map when
doing a cache sync which is wasteful and will slow things down. Check
to see if the value we're about to write is the default and don't bother
restoring it if it is, either the value will have been retained or the
device will have been reset and holds the value already.

We should really store the defaults in the nodes but this resolves the
immediate issue.

Lars-Peter Clausen 874ce77bc3 ASoC: AD1836: Add AD1835/AD1837/AD1838/AD1839 support
The AD183X codec devices are mostly register compatible and can easily be
supported by the same driver.  The main difference between those devices
is the number of DACs and ADCs.

This patch adjusts the driver to allocate the controls, DAPM widgets and
routes for the DACs and ADCs dynamically based on the chip type.

The AD1836 is a bit special in that it supports different modes for its second
ADC, so it needs some special handling. Right now the driver hardcodes the mode
to the differential PGA mode.

Mark Brown a1e9adc00e ASoC: Support edge triggered IRQs for WM8915
Really this should be something the IRQ core can cope with for us but since
it doesn't currently do so (at least for threaded interrupts like this) do
so in the driver. This allows us to run with interrupt controllers that
only support edge triggered interrupts.

Linus Torvalds 46f2cc8051 ALSA: fix hda AZX_DCAPS_NO_TCSEL quirk check in driver_caps
Commit 9477c58e33 ("ALSA: hda - Reorganize controller quriks with bit
flags") changed the driver type compares into various quirk bits.
However, the check for AZX_DCAPS_NO_TCSEL got reverted: instead of
clearing TCSEL for chipsets that have that standard capability, it
cleared then when the NO_TCSEL bit was set.

This can lead to noise and repeated sounds - a weird "echo" behavior.
As the comment just above says: "Ensuring these bits are 0 clears
playback static on some HD Audio codecs".  Which is definitely true at
least on my Core i5 Westmere system.

Stephen Warren 1007da0604 ASoC: Fix dapm_is_shared_kcontrol so everything isn't shared
Commit af46800 ("ASoC: Implement mux control sharing") introduced
function dapm_is_shared_kcontrol.

When this function returns true, the naming of DAPM controls is derived
from the kcontrol_new. Otherwise, the name comes from the widget (and
possibly a widget's naming prefix).

A bug in the implementation of dapm_is_shared_kcontrol made it return 1
in all cases. Hence, that commit caused a change in control naming for
all controls instead of just shared controls.

Specifically, a control is always considered shared because it is always
compared against itself. Solve this by never comparing against the widget
containing the control being created.

Equally, controls should never be shared between DAPM contexts; when the
same codec is instantiated multiple times, the same kcontrol_new will be
used. However, the control should no be shared between the multiple
instances.

I tested that with the Tegra WM8903 driver:
* Shared is now mostly 0 as expected, and sometimes 1.
* The expected controls are still generated after this change.

However, I don't have any systems that have a widget/control naming
prefix, so I can't test that aspect.

Thanks for Jarkko Nikula for pointing out how to fix this.

Jarkko Nikula ea77b94774 ASoC: Fix power down for widgetless per-card DAPM context case
Commit 52ba67b ("ASoC: Force all DAPM contexts into the same bias state")
powers up all the DAPM contexts in a card if any DAPM context becomes
active. Unfortunately power down newer happens if per-card DAPM context
doesn't have any widgets.

Reason for this is that power state of per-card DAPM context without
widgets is never cleared and thus all the DAPM contexts remain permanently
active. Test for widgetless calling DAPM context in dapm_power_widgets()
doesn't work for per-card DAPM context since power change is never
originating from widgetless per-card DAPM context.

Fix this by pre-clearing power state flag of non-codec DAPM context at the
beginning of power sequence.

Stephen Warren 82e14e8bdd ASoC: core: Don't schedule deferred_resume_work twice
For cards that have two or more DAIs, snd_soc_resume's loop over all
DAIs ends up calling schedule_work(deferred_resume_work) once per DAI.
Since this is the same work item each time, the 2nd and subsequent
calls return 0 (work item already queued), and trigger the dev_err
message below stating that a work item may have been lost.

Solve this by adjusting the loop to simply calculate whether to run the
resume work immediately or defer it, and then call schedule work (or not)
one time based on that.

Note: This has not been tested in mainline, but only in chromeos-2.6.38;
mainline doesn't support suspend/resume on Tegra, nor does the mainline
Tegra ASoC driver contain multiple DAIs. It has been compile-checked in
mainline.

Ben Gardiner 52e2c5d38e ASoC: davinci-pcm: convert to BATCH mode
The davinci-pcm driver's snd_pcm_ops pointer function currently calls into
the edma controller driver to read the current positions of the edma channels
to determine pos to return to the ALSA framework. In particular,
davinci_pcm_pointer() calls edma_get_position() and the latter has a comment
indicating that "Its channel should not be active when this is called" whereas
the channel is surely active when snd_pcm_ops.pointer is called.

The operation of davinci-pcm in capture and playback appears to follow close
the other pcm drivers who export SNDRV_PCM_INFO_BATCH except that davinci-pcm
does not report it's positions from pointer() using the last transferred
chunk. Instead it peeks directly into the edma controller to determine the
current position as discussed above.

Convert the davinci-pcm driver to BATCH mode: count the periods elapsed in the
prtd->period member and use its value to report the 'pos' to the alsa
framework in the davinci_pcm_pointer function.

There is a phase offset of 2 periods between the position used by dma setup
and the position reported in the pointer function. Either +2 in the dma
setup or -2 in the pointer function (with wrapping, both) accounts for this
offset -- I opted for the latter since it makes the first-time setup clearer.

Ben Gardiner ef39eb6f21 ASoC: davinci-pcm: fix audible glitch on 2nd ping-pong playback
The release of the dma channels was being performed in prepare and there was a
edma_resume call for the asp-channel only being executed on START, RESUME and
PAUSE_RELEASE.

The mcasp on da850evm with ping-pong buffers enabled was exhibiting an audible
glitch on every playback after the first. It was determined through trial and
error that the following two changes fix this problem:

1) Move the edma_start calls from prepare to trigger and 2) reverse the order
of starting the asp and ram channels.

Stephen Warren 5d44f927a5 ALSA: HDA: Unify HDMI hotplug handling.
This change unifies the initial handling of a pin's state with the code to
update a pin's state after a hotplug (unsolicited response) event. The
initial probing, and all updates, are now routed through hdmi_present_sense.

The stored PD and ELDV status is now always derived from GetPinSense verb
execution, and not from the data in the unsolicited response. This means:

a) The WAR for NVIDIA codec's UR.PD values ("old_pin_detect") can be
   removed, since this only affected the no-longer-used unsolicited
   response payload.

b) In turn, this means that most NVIDIA codecs can simply use
   patch_generic_hdmi instead of having a custom variant just to set
   old_pin_detect.

c) When PD && ELDV becomes true, no extra verbs are executed, because the
   GetPinSense that was previously executed by snd_hdmi_get_eld (really,
   hdmi_eld_valid) has simply moved into hdmi_present_sense.

d) When PD && ELDV becomes false, there is a single extra GetPinSense verb
   executed for codecs where old_pin_detect wasn't set, i.e. some NVIDIA,
   and all ATI/AMD and Intel codecs. I doubt this will be a performance
   issue.

The new unified code in hdmi_present_sense also ensures that eld->eld_valid
is not set unless eld->monitor_present is also set. This protects against
potential invalid combinations of PD and ELDV received from HW, and
transitively from a graphics driver.

Also, print the derived PD/ELDV bits from hdmi_present_sense so the kernel
log always displays the actual state stored, which will differ from the
values in the unsolicited response for NVIDIA HW where old_pin_detect was
previously set.

Finally, a couple of small tweaks originally by Takashi:

* Clear the ELD content to zero before reading it, so that if it's not
  read (i.e. when !(PD && ELDV)) it's in a known state.

* Don't show ELD fields in /proc ELD files when the ELD isn't valid.

The only possibility I can see for regression here is a codec where the
GetPinSense verb returns incorrect data. However, we're already exposed
to that, since that data is used (a) from hdmi_add_pin to set up the
initial pin state, and (b) within snd_hda_input_jack_report to query
a pin's presence value. As such, I don't believe any HW has bugs here.

Jarkko Nikula 9fb352b18b ASoC: tlv320aic3x: Do soft reset to codec when going to bias off state
TLV320AIC33, TLV320AIC34 and I believe others too in this family have some
hw bugs that cause that analogue and digital VDD supplies remain leaking
up to a few mA of current after certain use cases even the hw blocks inside
codec are driven to off.

Highest leakages occur after using the bypass paths inside codec but it
is possible to get smaller leakages just by toggling mute switches in
unused audio paths (i.e. no DAPM changes) while codec is on due another
active audio path.

While some cases are able to workaroud by making sure that e.g. output mixer
switches are muted before powering down the output stage this doesn't help
all the cases.

Therefore use the software reset command to clear possible leakage currents
since that works in every cases and affects only this codec instance. Only
drawback is that now cache sync is required everytime when codec bias comes
out from bias off state, not only when supply regulators were off.

Jarkko Nikula 2b39535b9e ASoC: core: Don't set "(null)" as a driver name
Commit 22de71b ("ASoC: core - allow ASoC more flexible machine name")
writes "(null)" to driver name string in struct snd_card if card->driver_name
is NULL. This causes segmentation faults with some user space ALSA utilities
like aplay and arecord.

Fix this by using the card->name if no driver name is specified.

Michael Williamson 2aba76f014 audio: tlv320aic26: fix PLL register configuration
The current PLL configuration code for the tlc320aic26 codec appears to assume a
hardcoded system clock of 12 MHz.  Use the clock value provided by the DAI_OPS
API for the calculation.

Tested using a MityDSP-L138 platform providing a 24.576 MHz clock.

Takashi Iwai 50e3bbf989 ALSA: hda - Use LPIB for ATI/AMD chipsets as default
ATI and AMD chipsets seem not providing the proper position-buffer
information, and it also doesn't provide FIFO register required by
VIACOMBO fix.  It's better to use LPIB for these.

Takashi Iwai 314c3ff476 Revert "ALSA: hda - Use position_fix=3 as default for AMD chipsets"
This reverts commit 447ee6a7cb.

The workaround introduced by this commit seems bogus.
The AMD chipsets don't provide proper position-buffer nor FIFO value
required by VIACOMBO fix.

Dimitris Papastamos 7e146b5586 ASoC: soc-cache: Cache a pointer to the last accessed rbnode
Whenever we are doing a read or a write through the rbtree code, we'll
cache a pointer to the rbnode.  To avoid looking up the register
everytime we do a read or a write, we first check if it can be found in
the cached register block, otherwise we traverse the rbtree and finally
cache the rbnode for future use.

Dimitris Papastamos 0944cc392e ASoC: soc-cache: Block based rbtree compression
This patch prepares the ground for the actual rbtree optimization patch
which will save a pointer to the last accessed rbnode that was used
in either the read() or write() functions.

Each rbnode manages a variable length block of registers.  There can be no
two nodes with overlapping blocks.  Each block has a base register and a
currently top register, all the other registers, if any, lie in between these
two and in ascending order.

The reasoning behind the construction of this rbtree is simple.  In the
snd_soc_rbtree_cache_init() function, we iterate over the register defaults
provided by the driver.  For each register value that is non-zero we
insert it in the rbtree.  In order to determine in which rbnode we need
to add the register, we first look if there is another register already
added that is adjacent to the one we are about to add.  If that is the case
we append it in that rbnode block, otherwise we create a new rbnode
with a single register in its block and add it to the tree.

In the next patch, where a cached rbnode is used by both the write() and the
read() functions, we also check if the register we are about to add is in the
cached rbnode (the least recently accessed one) and if so we append it in that
rbnode block.
