[alsa-devel] [PATCH 0/2] McBSP: OMAP3: Add sidetone feature
by Ilkka Koskinen 29 Jan '10

29 Jan '10

The first patch implements McBSP sidetone feature on OMAP3 while the second one provides ALSA interface for using it. The patch set is based on the patch Eduardo Valentin sent to alsa-devel mailing list in October 2009. Channel gain control and enabling the sidetone have been moved to ALSA interface as suggested in comments.

[alsa-devel] [PATCH v2] ASoC: clean up wm8974 and wm8978 clock divider handling
by Guennadi Liakhovetski 29 Jan '10

29 Jan '10

wm8974 and wm8978 codec drivers control DAC and ADC oversampling rates in their .set_clkdiv() methods, which is wrong, because these are simple boolean switches and not clock dividers. Move these bits to sound controls. Also remove manual configuration of the MCLK divider in wm8978, since it is configured automatically.

[alsa-devel] [PATCH] ASoC: remove bogus SLEEP mode from wm8978 driver
by Guennadi Liakhovetski 29 Jan '10

29 Jan '10

Tests showed, that bit 6 of the WM8978_POWER_MANAGEMENT_2 register of wm8978 affects codec clocks. Being useless for suspend / resume, it cannot be used in bias-level control either.

[alsa-devel] [PATCH 1/1] ASoC: AM3517: ASoC driver not getting compiled
by Anuj Aggarwal 29 Jan '10

29 Jan '10

Commit 761c9d45 (ASoC: Fix build of OMAP sound drivers) changes CONFIG_MACH_OMAP3517EVM -> CONFIG_SND_OMAP_SOC_OMAP3517EVM in the Makefile. Whereas the config option defined in Kconfig is SND_OMAP_SOC_AM3517EVM. Because of this, ASoC driver for AM3517 was not getting compiled.
