[alsa-devel] [PATCH] ASoC: Remove unused dapm_get_snd_card() and dapm_get_soc_card()
by Lars-Peter Clausen 24 Jul '13

24 Jul '13

These two functions were added two years ago in commit 4805608 ("ASoC: dapm - Add methods to retrieve snd_card and soc_card from dapm context.") but have remained unused so far. Considering that the dapm context actually has a direct pointer to the card the functions also seem to be unnecessary. E.g. the expressions 'dapm_get_soc_card(dapm)' and 'dapm->card' yield the same result.

[alsa-devel] [PATCH] ASoC: Samsung: Modify the I2S driver to support I2S on Exynos5420
by Padmavathi Venna 23 Jul '13

23 Jul '13

Exynos5420 added support for I2S TDM mode. For this, there are some register changes in the I2S controller. This patch adds the relevant register changes to support I2S in normal mode. This patch adds a quirk for TDM mode and if TDM mode is present all the relevent changes will be applied.

[alsa-devel] [PATCH 1/2] ASoC: Build adau1701 when SND_SOC_ALL_CODECS is selected
by Lars-Peter Clausen 23 Jul '13

23 Jul '13

The adau1701 driver was removed from SND_SOC_ALL_CODECS in commit commit ee8c7e9 ("ASoC: Remove adau1701 from SND_SOC_ALL_CODECS due to Sigma dependency") due to the dependency on the SigmaDSP firmware loader which was only available on a limited set of platforms. This was fixed quite some time ago in commit 40216ce7 ("ASoC: Move SigmaDSP firmware loader to ASoC") though, so we can add the driver back again to SND_SOC_ALL_CODECS.

[alsa-devel] [PATCH] ARM: kirkwood: extend the kirkwood pcm/dma driver for DT usage
by Jean-Francois Moine 23 Jul '13

23 Jul '13

The kirkwood pcm/dma driver is used without DT in the Kirkwood machine. This patch adds a DT compatible definition for use in other Marvell machines as the Armada 88AP510 (Dove).

[alsa-devel] [PATCH] alsa-utils: fix wrong alias for signal.h
by John Spencer 23 Jul '13

23 Jul '13

in POSIX, there is no <sys/signal.h>. it's merely a legacy alias used by glibc, and the header does nothing else than including <signal.h>. so let's do the right thing and use the right name, which works everywhere. Signed-Off-By: John Spencer <maillist-alsa(a)barfooze.de>

Return SNDRV_PCM_POS_XRUN (snd_pcm_uframes_t) instead of SNDRV_PCM_STATE_XRUN (snd_pcm_state_t) from the pointer function of 6fire, as expected by snd_pcm_update_hw_ptr0(). Caught by sparse.
