Different operating modes can be setup directly as different register

There is a small but significant difference between imx21-ssi and

imx51-ssi has to reconfigure the SSI unit while it is running. Otherwise
it would not be possible to have two streams in parallel. The new SDMA
unit in imx51 and above has to be configured before the first DMA
request arrives. Therefor we need to setup TDMAE/RDMAE just before

It turned out that some AMD HDMI controllers still don't provide
proper values in GCAP register (all zero), and the driver assigns only
one stream in that case, although the connected codec chip supports
more than one stream.
In this patch, the default max number of streams for AMD HDMI
controllers is increased to 8, which should suffice for most use
cases. The overhead by this increase is more azx_dev struct and BDL
allocations, so it's negligible. Of course, if the controller
provides a proper GCAP register, the register value would be used.

This is a quick fix for the below two issues when building spdif as modules.
1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2)
snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create
imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe
it again due to the execution platform_driver_unregister() in probe() when
meeting -EPROBE_DEFER at Step 2.
2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok",
'rmmod snd-soc-imx-spdif' would cause kernel dump with warning:
WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90()

This should be caused by disordered resourse releasing of the whole link.
And trying to unregister the card and then CODEC dev can't fix this issue.
Thus this patch just provides a simple fix to these two bugs by using the
snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that
there's no need to handle the registering and unregistering of CODEC or

This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.
This conversion relies on a few sets of patches in branches from outside
the Tegra tree:
1) A patch to add an DMA channel request API which allows deferred probe
to be implemented.
2) A patch to implement a common part of the of_xlate function for DMA
controllers.
3) Some ASoC patches (which in turn rely on (1) above), which support
deferred probe during DMA channel allocation.
4) The Tegra clock driver changes for 3.14.
Consequently, this branch is based on a merge of all of those external
branches.
In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:
a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
conflicts.
b) The DRM tree, which introduces new code that relies on the reset
controller framework introduced in this branch, and to avoid
conflicts.

to make headphones and front speaker use DAC 0x02, and subwoofer use

to node 0x03, so they can only use DAC 0x02.
In addition, the 5460 and 5470 differs in the sense that 5470 also

I've replaced these with the singular "they" variant. Some are simply

When a Kconfig of a codec driver doesn't match with the controller
(CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic
probing. Unfortunately kbuild can't give such a restriction, but at
least, it's possible to show a warning if such a condition is found.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons. The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in. And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.
But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.
That said, better to let people fallen into a pitfall than being too
smart and restrict something. Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.

ASoC: Fixes for v3.13
The fixes here are all driver specific ones, none of which particularly
stand out but all of which are useful to users of those drivers.

Currently, the driver only supports configuration of the lower sample
rate (FSL) on the ISRCs. With the higher rate being fixed a SYSCLK, this
patch adds support for configuring the higher sample rate (FSH).

spear_pcm_request_chan() is almost identical to

latter:
a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data

b) dma_data->filter_data rather than dma_data should be passed to

Function sgtl5000_enable_regulators() is somehow odd in handling the
optional external VDDD supply. The driver can only enable this supply
on SGTL5000 chip before revision 0x11, and of course when this external
VDDD is present. It currently does something like below.
1. Check if regulator_bulk_get() on VDDA, VDDIO and VDDD will fail. If
it fails, VDDD must be absent and it falls on internal LDO by calling
sgtl5000_replace_vddd_with_ldo(). Otherwise, VDDD is used. And in
either case, regulator_bulk_enable() will be called to enable
3 supplies.
2. In case that SGTL5000 revision is later than 0x11, even if external
VDDD is present, it has to roll back the 'enable' and 'get' calls
with regulator_bulk_disable() and regulator_bulk_free(), and starts
over again by calling sgtl5000_replace_vddd_with_ldo() and
regulator_bulk_enable().
Such back and forth calls sequence is complicated and unnecessary.
Also, since commit 4ddfebd (regulator: core: Provide a dummy regulator
with full constraints), regulator_bulk_get() will always succeeds
because of the dummy regulator. Thus the VDDD detection is broken.
The patch changes the flow to something like the following, which should
be more reasonable and clear, and also fix the VDDD detection breakage.
1. Check if we're running a chip before revision 0x11, on which an
external VDDD can possibly be an option.
2. If it is an early revision, call regulator_get_optional() to detect
whether an external VDDD supply is available.
3. If external VDDD is present, call sgtl5000_replace_vddd_with_ldo() to
update sgtl5000->supplies info.
4. Drop regulator_bulk_get() call in sgtl5000_replace_vddd_with_ldo(),
and call it in sgtl5000_enable_regulators() no matter it's an
external VDDD or internal LDO.
5. Call regulator_bulk_enable() to enable these 3 regulators.

This patch depends on "ASoC: tegra: use reset framework" to compile,
which is ack'd and slated to go through a (large) topic branch in the
Tegra tree. So, we can either:
a) Merge that Tegra topic branch into the ASoC tree, then apply this.
Note that I haven't created the topic branch yet, since I'm still
waiting for DMA dependencies to be applied.
b) Apply this change to the Tegra tree too. This change isn't directly
related to the changes in the Tegra tree; it just makes use of the new
reset controller feature that's introduced there.
This AT91 specific Kconfig option removed the code that dealt with
programmable clocks. Each AT91 SoC embeds programmable clocks and
there is little gain to remove this code in case that such a clock
is not used.
If this option is not selected, it causes certain drivers to fail
to build. We simply remove this option instead of adding code just
to build a workaround.

Since all Exynos platforms have been converted to dmaengine and many of
the older platforms are in the process of conversion they do not need to
use the legacy s3c-dma APIs for DMA but can instead use the standard ASoC
dmaengine helpers. This both allows them to benefit from improvements
implemented in the generic code and supports multiplatform.
This patch includes some fixes from Padma for Exynos SoCs, her testing

By passing no flags when calling snd_dmaengine_pcm_register() from
tegra_pcm.c, we end up using dma_request_slave_channel() rather than
dmaengine_pcm_compat_request_channel(), and hence rely on the standard
DMA DT bindings and stashing the DMA slave ID away during channel
allocation. This means there's no need to use a custom DT property to
store the slave ID. So, remove all the code that parsed it.

The Tegra30 I2S driver currently allocates DMA FIFOs from the AHUB only
when an audio stream starts playback. This is theoretically nice for
resource sharing, but makes no practical difference for any configuration
the drivers currently support. However, this deferral prevents conversion
to the standard DMA DT bindings, since conversion requires knowledge of
the specific DMA channel to be allocated, which in turn depends on which
specific FIFO was allocated.
For this reason, move the FIFO allocation into probe() to allow later
conversion to the standard DMA DT bindings.

Call pm_runtime_get_sync() before all register accesses; the HW requires
clocks to be running when accessing registers.
This hasn't been needed to date, since all register IO was performed

Tegra's clock driver now provides an implementation of the common
reset API (include/linux/reset.h). Use this instead of the old Tegra-
specific API; that will soon be removed.
This change also renames "clock"/"clk" to "modules"/"mod" in symbols
related to entries in configlink_clocks[], since:
- We don't care about clock handles any more, but rather reset handles,
so the old name isn't applicable.
- It really is a list of modules on the bus, about which we currently
only care about reset handles.
If we start caring about any other aspect of the modules in the future,
we won't have to rename all these symbols again.
Note: The addition of "depends COMMON_CLOCK" is something that was missing
before, not a new requirement.

AD1986A codec is a pretty old codec and has really many hidden
restrictions. One of such is that each DAC is dedicated to certain
pin although there are possible connections. Currently, the generic
parser tries to assign individual DACs as much as possible, and this
lead to two bad situations: connections where the sound actually
doesn't work, and connections conflicting other channels.
We may fix this by trying to find the best connections more harder,
but as of now, it's easier to give some hints for paired DAC/pin
connections and honor them if available, since such a hint is needed
only for specific codecs (right now only AD1986A, and there will be
unlikely any others in future).

In case a single HDA card has both HDMI and S/PDIF outputs, the S/PDIF
outputs will have their IEC958 controls created starting from index 16
and the HDMI controls will be created starting from index 0.
However, HDMI simple_playback_build_controls() as used by old VIA and
NVIDIA codecs incorrectly requests the IEC958 controls to be created
with an S/PDIF type instead of HDMI.
In case the card has other codecs that have HDMI outputs, the controls
will be created with wrong index=16, causing them to e.g. be unreachable
by the ALSA "hdmi" alias.
Fix that by making simple_playback_build_controls() request controls
with HDMI indexes.
Not many cards have an affected configuration, but e.g. ASUS M3N78-VM
contains an integrated NVIDIA HDA "card" with:
- a VIA codec that has, among others, an S/PDIF pin incorrectly
labelled as an HDMI pin, and
- an NVIDIA MCP7x HDMI codec.

Treat both negative and zero return values from clk_round_rate()
as errors. This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.
Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error; all other values will be
considered valid rates. The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.

Not all channels have been initialized, so far, especially when aamix
NID itself doesn't have amps but its leaves have. This patch fixes
these holes. Otherwise you might get unexpected loopback inputs,
e.g. from surround channels.

An earlier patch overlooked this when the compatible has been changed from
omap2 -> am33x.
Rename omap2_mcasp_pdata to am33xx_mcasp_pdata.

Instead of passing __iomem address (mcasp->base + register_offset) pass
the main mcasp structure and only access the mcasp->base in the low level
IO functions.
In most cases this helps with code readability and it will make it easier
to switch over to regmap in the future.

The IP in DRA7xx is similar to the IP found in TI81xxAM3xxx/AM4xxx type of
SoCs but it is is integrated with sDMA instead of eDMA. The suitable pcm
driver for DRA7xx is the omap-pcm driver which is using dmaengine.
In the driver we can configure both dma related structures used for eDMA and
sDMA. The only thing we need to make sure that we set the correct dma_data
at startup with snd_soc_dai_set_dma_data()

The audio data to/from McASP can be sent/received via two method:
Via the data port (preferred) or via the configuration bus.
Currently the driver assumes that all data communication will be done via
the data port.
This patch adds support for selecting the configuration port as data
interface.

The FIFO registers base address is different in dm646x compared to newer
SoCs with McASP IP. Instead of using two paths (switch/case) to handle the
difference we can simply pick the correct base address beforehand and use
offsets to address the register we need to configure.
With this change the indentation depth can be reduced as well.
