ca2b029515 ASoC: generic-dmaengine-pcm: Use SNDRV_DMA_TYPE_DEV_IRAM as default
When allocating memory space for DMA buffer, use on-chip internal SRAM
as default choice to save power. Since the core would allocate memory
from traditional external memory if iram allocation failed, we don't
need to worry about any side effect.

bf4edea863 ASoC: dapm: Use WARN_ON() instead of BUG_ON()
Leaving BUG_ON() in a core layer like dapm is rather inappropriate as
it leads to panic(), even though sanity checks might be still useful
for debugging.
Instead, Use WARN_ON(), and handle the error cases accordingly.

6c452bdac7 ASoC: wm_adsp: Fix BUG_ON() and WARN_ON() usages
This patch does:
- Move the sanity check with WARN_ON() in wm_adsp_region_to_reg() and
  remove the checks in the callers,
- Fix wrong WARN_ON() usages, replaced with WARN(),
- Fix unreachable or wrong BUG_ON() usages and replace with WARN_ON().

a6ed0608bd ASoC: Replace BUG() with WARN()

We currently assume that the DMA Slave Config will be fully populated

68f9672b13 ASoC: fsl: imx-pcm-fiq: remove bogus period delta calculation
Originally snd_hrtimer_callback() used iprtd->period_time for
some jiffies based estimation to determine the right moment
to call snd_pcm_period_elapsed(). As timer drifts may well be a
problem, this was changed in commit b4e82b5b78 to be based
on buffer transmission progress, using iprtd->offset and
runtime->buffer_size to calculate the amount of data since last
period had elapsed.

Unfortunately, iprtd->offset counts in bytes, while
runtime->buffer_size counts frames, so adding these to find some
delta is like comparing apples and oranges, and eventually results
in negative delta values every now and then. This is no big harm,
because it simply causes snd_pcm_period_elapsed() being called
more often than necessary, as negative delta is taken for a
large unsigned value by implicit conversion rule.
Nonetheless, the calculation is broken, so one would replace
the runtime->buffer_size by its equivalent in bytes.

But then, there are chances snd_pcm_period_elapsed() is called
late, because calculating the moment for the elapsed period
into delta is based against the iprtd->last_offset, which is not
necessarily the first byte of the period in question, but some
random byte which the FIQ handler left us with in r8/r9 by
accident. Again, negative impact is low, as there are plenty of
periods already prefilled with data, and snd_pcm_period_elapsed()
will probably be called latest when the following period is
reached. However, the calculation is conceptually broken, and we
are best off removing the clever stuff altogether.

snd_pcm_period_elapsed() is now simply called once everytime
snd_hrtimer_callback() is run, which may not be most accurate,
but at least this way we are quite sure we dont miss an end of
period. There is not much extra effort wasted by superfluous
calls to snd_pcm_period_elapsed(), as the timer frequency
closely matches the period size anyway.

988e8cc41e ASoC: Add pinctrl PM to components of active DAIs
It's quite popular that more drivers are using pinctrl PM, for example:
(Documentation/devicetree/bindings/arm/primecell.txt). Just like what
runtime PM does, it would deactivate and activate pin group depending
on whether it's being used or not.

And this pinctrl PM might be also beneficial to cpu dai drivers because
they might have actual pinctrl so as to sleep their pins and wake them
up as needed.

To achieve this goal, this patch sets pins to the default state during
resume or startup; While during suspend and shutdown, it would set pins
to the sleep state.

As pinctrl PM would return zero if there is no such pinctrl sleep state
settings, this patch would not break current ASoC subsystem directly.

[ However, there is still an exception that the patch can not handle,
that is, when cpu dai driver does not have pinctrl property but another
device has it. (The AUDMUX <-> SSI on Freescale i.MX6 series for example.
SSI as a cpu dai doesn't contain pinctrl property while AUDMUX, an Audio
Multiplexer, has it). In this case, this kind of cpu dai driver needs to
find a way to obtain the pinctrl property as its own, by moving property
from AUDMUX to SSI, or creating a pins link/dependency between these two
devices, or using a more decent way after we figure it out. ]

c9bd5e690a DMA-API: sound: fix dma mask handling in a lot of drivers
This code sequence is unsafe in modules:

static u64 mask = DMA_BIT_MASK(something);
...
	if (!dev->dma_mask)
		dev->dma_mask = &mask;

as if a module is reloaded, the mask will be pointing at the original
module's mask address, and this can lead to oopses.  Moreover, they
all follow this with:

	if (!dev->coherent_dma_mask)
		dev->coherent_dma_mask = mask;

where 'mask' is the same value as the statically defined mask, and this
bypasses the architecture's check on whether the DMA mask is possible.

Fix these issues by using the new dma_coerce_coherent_and_mask()
function.

90130d2e8f ASoC: dmaengine: Use filter_data rather than dma_data for compat requests
When using the legacy filter function channel requests we currently pass
the audio specific struct snd_dmaengine_dai_dma_data which isn't likely to
be helpful for actual filtering. Since there's already a field in the
structure called filter_data clearly intended for use here convert the
driver to use that.

All existing users of plain filter functions have been converted to use
an explicit compat function to override this behaviour except i.MX which
is working around this issue in its filter function and is updated to
just use filter_data directly here.
