[alsa-devel] [PATCH] 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 1/1] ASoC: AM3517: ASoC driver not getting compiled

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.
