[alsa-devel] am335x+tlv320aic3x
Hi List,
I am trying to get Beaglebone workign with the audio extension board (aka cape) that is using tlv320aic3x codec. I want it to run 3.14 and use vanilla kernel without dynamic DT overlay patches.
So I have take the current overlay DT [1] and made converted it [2]. The result is that it boots and detects the Davinci module, but doesn't get the codec.

My kernel config includes this:
CONFIG_SND_OMAP_SOC=m CONFIG_SND_OMAP_SOC_MCBSP=m CONFIG_SND_OMAP_SOC_OMAP_TWL4030=m CONFIG_SND_SOC_TWL4030=m CONFIG_SND_DAVINCI_SOC=m CONFIG_SND_AM33XX_SOC_EVM=m CONFIG_SND_DAVINCI_SOC_MCASP=m CONFIG_SND_HRTIMER=m

What is the revision of audio cape you have? The fragment is for RevA, RevB of the cape is significantly different.

You are missing the CONFIG_SND_SOC_TLV320AIC3X

Sure, I have checked this and my audio cape is of the older revision A1.

Sorry, looks like I didn't copy everything here. This is what I have:
$ zcat /proc/config.gz | grep ^CONFIG_SND CONFIG_SND=m CONFIG_SND_TIMER=m CONFIG_SND_PCM=m CONFIG_SND_DMAENGINE_PCM=m CONFIG_SND_HWDEP=m CONFIG_SND_RAWMIDI=m CONFIG_SND_COMPRESS_OFFLOAD=m CONFIG_SND_JACK=y CONFIG_SND_SEQUENCER=m CONFIG_SND_SEQ_DUMMY=m CONFIG_SND_HRTIMER=m CONFIG_SND_SEQ_HRTIMER_DEFAULT=y CONFIG_SND_SUPPORT_OLD_API=y CONFIG_SND_VERBOSE_PROCFS=y CONFIG_SND_VERBOSE_PRINTK=y CONFIG_SND_DEBUG=y CONFIG_SND_DEBUG_VERBOSE=y CONFIG_SND_RAWMIDI_SEQ=m CONFIG_SND_DRIVERS=y CONFIG_SND_ARM=y CONFIG_SND_SPI=y CONFIG_SND_USB=y CONFIG_SND_USB_AUDIO=m CONFIG_SND_SOC=m CONFIG_SND_DAVINCI_SOC=m CONFIG_SND_DAVINCI_SOC_MCASP=m CONFIG_SND_DAVINCI_SOC_GENERIC_EVM=m CONFIG_SND_AM33XX_SOC_EVM=m CONFIG_SND_OMAP_SOC=m CONFIG_SND_OMAP_SOC_MCBSP=m CONFIG_SND_OMAP_SOC_HDMI=m CONFIG_SND_OMAP_SOC_OMAP_TWL4030=m CONFIG_SND_OMAP_SOC_OMAP_HDMI=m CONFIG_SND_SOC_I2C_AND_SPI=m CONFIG_SND_SOC_HDMI_CODEC=m CONFIG_SND_SOC_TLV320AIC3X=m CONFIG_SND_SOC_TWL4030=m
As you can see, the TLV320AIC3X module is enable and I am also able to load it, but nothing happens.
I also wonder if there is a way of configuring this by means of passing module params instead of device tree, but couldn't find any information on this.
After reading the driver source code, I figured I should try changing the device tree code to use "ti,tlv320aic3x-hifi", but that didn't affect anything. I have updated the gist with the effective device tree obtain from the running system [3] and the respective source code [4].

Peter, thanks for looking into this! I'll make sure that I get the results posted online, so the community can use capes without DT overlay patches. Sorry for my bad english in the last email, was typing in a hurry.
Cheers,
