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

2012-08-09T15:23:15+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: wm8962: Redo early init of the part on resume

2012-08-09T15:22:37+00:00

commit e4dd76788c7e5b27165890d712c8c4f6f0abd645 upstream.

Ensure robust startup of the part by going through the reset procedure
prior to resyncing the full register cache, avoiding potential intermittent
faults in some designs.

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

2012-08-09T15:22:37+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: dapm: Fix locking during codec shutdown

2012-08-09T15:22:37+00:00

commit 01005a729a17ab419f61a366e22f3419e7a2c3fe upstream.

Codec shutdown performs a DAPM power sequence that might cause conflicts
and/or race conditions if another stream power event is running simultaneously.
Use card's dapm mutex to protect any potential race condition between them.

ASoC: tlv320aic3x: Fix codec pll configure bug

2012-06-29T07:18:03+00:00

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: remove duplicate code

It seems that the code duplication was added at a merge operation.

ASoC: tegra+wm8903: turn of mic detect when card is removed

2012-06-12T03:38:48+00:00

If mic detect is left enabled and the WM8903 detects a status change,
the WM8903 driver will make a callback against the free()d jack, which
will cause a crash.

This problem can be triggered by fully initializing an audio card, then
removing and re-inserting the machine driver module.
