the twl6040 codec is missing. > /sys/kernel/debug/asoc/dais:dmic-hifi > /sys/kernel/debug/asoc/dais:omap-dmic > /sys/kernel/debug/asoc/dais:omap-mcpdm > /sys/kernel/debug/asoc/dais:snd-soc-dummy-dai > /sys/kernel/debug/asoc/dais:hdmi-audio-codec as well the dai for the twl6040. > /sys/kernel/debug/asoc/platforms:omap-pcm-audio > /sys/kernel/debug/asoc/platforms:snd-soc-dummy > > So the answer is... no. Hrm. I don't think you can build the twl6040 MFD core driver as a module. Do you have CONFIG_TWL6040_CORE=y ? We have MFD for twl6040 since it provides audio and vibra functionality as well. Can you check if you have this commit: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=8eaeb9393397be8eb700ab38a69c450975463b77 This is the second patch to separate the twl6040 from twl-core. If you are missing this patch twl6040 will not probe (twl core will not register the audio if we have twl6030). -- Péter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
