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.

ALSA: hda - Turn on PIN_OUT from hdmi playback prepare.

2012-08-02T13:37:53+00:00

commit 9e76e6d031482194a5b24d8e9ab88063fbd6b4b5 upstream.

Turn on the pin widget's PIN_OUT bit from playback prepare. The pin is
enabled in open, but is disabled in hdmi_init_pin which is called during
system resume.  This causes a system suspend/resume during playback to
mute HDMI/DP. Enabling the pin in prepare instead of open allows calling
snd_pcm_prepare after a system resume to restore audio.

ALSA: hda - Add support for Realtek ALC282

2012-08-02T13:37:52+00:00

commit 4e01ec636e64707d202a1ca21a47bbc6d53085b7 upstream.

This codec has a separate dmic path (separate dmic only ADC),
and thus it looks mostly like ALC275.

ALSA: hda - Fix power-map regression for HP dv6 & co

2012-07-12T03:32:08+00:00

commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 upstream.

The recent fix for power-map controls (commit b0791dda813) caused
regressions on some other HP laptops.  They have fixed pins but these
pins are exposed as jack-detectable.  Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.

This patch adds the check of connection and it assumes the no jack
detection is available for fixed pins no matter what pin capability
says.

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).

ALSA: hda - Add Realtek ALC280 codec support

2012-07-04T04:44:29+00:00

commit befae82e2906cb7155020876a531b0b8c6c8d8c8 upstream.

This chip looks very similar to ALC269 and ALC27* variants. The bug reporter
has verified that sound was working after this patch had been applied.

ALSA: HDA: Pin fixup for Zotac Z68 motherboard

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

commit edfe3bfc1b779ddda9bcff523eb022dda37b93c8 upstream.

Pin 0x1b was connected to the front panel connector, which according to
the HDA standard should contain a mic and a headphone. In this case,
the headphone was listed as "line out" by BIOS.

ALSA: hda - Suppress auto-mute feature on some machines with ALC861

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

commit e652f4c861fb7f1f59ff0828db0d85578471932d upstream.

A few machines with ALC861 & co are reported not to work properly with
the auto-mute feature in software.  The auto-mute feature is implemented
in the hardware level, and the jack-detection never works with them.

Also, rename the fixup index as ALC861_FIXUP_* to follow the standard.
