ASoC: samsung dma - Don't indicate support for pause/resume.

2012-10-10T02:30:44+00:00

commit 57b2d68863f281737d8596cb3d76d89d9cc54fd8 upstream.

The pause and resume operations indicate that the stream can be
un-paused/resumed from the exact location they were paused/suspended.
This is not true for this driver, the pause and suspend triggers share
the same code path with stop, they flush all pending DMA transfers.
This drops all pending samples.  The pause_release/resume triggers are
the same as start, except that prepare won't be called beforehand,
nothing will be enqueued to the DMA engine and nothing will happen (no
audio).  Removing the pause flag will let apps know that it isn't
supported.  Removing the resume flag will cause user space to call
prepare and start instead of resume, so audio will continue playing when
the system wakes up.

Before removing the pause and resume flags, I tested this on an exynos
5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a
write error.  Suspend/resume testing led to the same result.  Removing
the two flags fixes suspend/resume (since snd_pcm_prepare is called
again). And leads to a proper reporting of pause not supported.

ASoC: wm9712: Fix microphone source selection

2012-09-12T02:37:09+00:00

commit ccf795847a38235ee4a56a24129ce75147d6ba8f upstream.

Currently the microphone input source is not selectable as while there is
a DAPM widget it's not connected to anything so it won't be properly
instantiated. Add something more correct for the input structure to get
things going, even though it's not hooked into the rest of the routing
map and so won't actually achieve anything except allowing the relevant
register bits to be written.

ASoC: wm8994: Ensure there are enough BCLKs for four channels

2012-08-09T23:24:48+00:00

commit b8edf3e5522735c8ce78b81845f7a1a2d4a08626 upstream.

Otherwise if someone tries to use all four channels on AIF1 with the
device in master mode we won't be able to clock out all the data.

ASoC: dapm: Fix _PRE and _POST events for DAPM performance improvements

2012-08-02T13:37:59+00:00

commit 0ff97ebf0804d2e519d578fcb4db03f104d2ca8c upstream.

Ever since the DAPM performance improvements we've been marking all widgets
as not dirty after each DAPM run. Since _PRE and _POST events aren't part
of the DAPM graph this has rendered them non-functional, they will never be
marked dirty again and thus will never be run again.

Fix this by skipping them when marking widgets as not dirty.

ASoC: tlv320aic3x: Fix codec pll configure bug

2012-07-12T03:32:03+00:00

commit c9fe573a6584034670c1a55ee8162d623519cbbf upstream.

In sound/soc/codecs/tlv320aic3x.c

        data = snd_soc_read(codec, AIC3X_PLL_PROGA_REG);
        snd_soc_write(codec, AIC3X_PLL_PROGA_REG,
                      data | (pll_p << PLLP_SHIFT));

In the above code, pll-p value is OR'ed with previous value without
clearing it. Bug is not seen if pll-p value doesn't change across
Sampling frequency.

However on some platforms (like AM335x EVM-SK), pll-p may have different
values across different sampling frequencies. In such case, above code
configures the pll with a wrong value.
Because of this bug, when a audio stream is played with pll value
different from previous stream, audio is heard as differently(like its
stretched).

ASoC: wm8994: Apply volume updates with clocks enabled

2012-06-19T22:18:13+00:00

commit bfd37bb5f681961e255fd2f346c20fdae2ef3f27 upstream.

Volume updates may not be acted upon if there is no clock applied when
the volume update is written. Ensure this doesn't happen by writing out
registers with volume updates after we enable each of the clocks.

There are more registers updated than before as previously we were
relying on wm_hubs to set those for controls it manages.

ASoC: tlv312aic23: unbreak resume

2012-05-11T12:14:57+00:00

commit e875c1e3e758447ba81ca450d89434b3b0496d37 upstream.

* commit f9dfbf9 "ASoC: tlv320aic23: convert to soc-cache" leads to
a bug preventing resumeof the codec as regmap expects a 9 bits data
register but 0xFFFF is passed in tlv320aic23_set_bias_level and this
values gets cached preventing any write to the TLV320AIC23_PWR
register as the final value produced by regmap is (register << 9) | value

* this patch solves the problem by only working on the 9 bits the
register contains.
