[PATCH 1/2] ARM: dts: da850-lcdk: Audio support via simple-card

[Karl Beldan]

The LCDK embeds a TLV320AIC3106 connected to the SoC McASP for analog
audio. This relies on the 'dummy' regulator as the codec is always on.
Quality is good with arecord -pipe- aplay on Line In/Line Out.
The MIC path doesn't seem to work yet.

This patch does not apply because Kevin already added some missing audio
modules through commit "ARM: davinci_all_defconfig: enable DA850 audio
as modules"

Can you please rebase on master branch of my tree[1] and resend?

I tested the patch and I could not get the MIC to work as well. I
suggest dropping the MIC path parts till that is debugged and root caused.

It will be nice to add the codec regulators as well (and that in turn
needs the PMIC to be populated). Although I wont insist on that since
the regulators are optional properties.

Rest of the patch looks good to me.

I checked out your tree.
With Kevin's patch the needed modules get selected without needing 2/2.

However I don't know why he used:
 CONFIG_SND_DA850_SOC_EVM=m
instead of: 
 CONFIG_SND_DAVINCI_SOC_MCASP=m
 CONFIG_SND_SOC_TLV320AIC3X=m
The former seems to me to be pre-DT style config. I used the latter in
2/2 and thought that's what we'd start switching to ? Unless it is for
pre-DT compatibility ?

In the patch comment I stated it relied on the dummy regulator as the
codec is always on but maybe I should have been more precise: it is not
out of convenience to keep things on, it is by HW design: I mentioned
it in the comment of "ARM: dts: da850: Add basic DTS for the LCDK":
 "the main PMIC, different and hard-wired on the LCDK (the LDOs and
 DCDCs are always on)" after reviewing the schematics.
I could add that in the patch comment.

Thanks for reviewing.

In the patch comment I stated it relied on the dummy regulator as the
codec is always on but maybe I should have been more precise: it is not
out of convenience to keep things on, it is by HW design: I mentioned
it in the comment of "ARM: dts: da850: Add basic DTS for the LCDK":
 "the main PMIC, different and hard-wired on the LCDK (the LDOs and
 DCDCs are always on)" after reviewing the schematics.
I could add that in the patch comment.

Thanks for reviewing.

I don't think this is related to DT. As you said,
CONFIG_SND_DA850_SOC_EVM selects CONFIG_SND_DAVINCI_SOC_MCASP and
CONFIG_SND_SOC_TLV320AIC3X anyway.

To be honest, I am okay either way. Copying Peter to see if he has any
preference.

I see. PMIC on the LCDK is not software configurable at all. I think
what you have in the patch comment is already okay. More explanation
wont harm though :)
