This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.

The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.

The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

This is more complex than you need, just write a standalone volatile
function with some comments in it.

Make this meaningful or omit it.

Use the define in the array size to help check everything lines up.

Off not off - be consistent both internally and with the general style.

SP?

There's no overlap with the enable bits?  In general it would seem nicer
to have a switch based on the register bits used for the enable rather
than the tree of string comparisions but it's probably not that big a
deal overall.

Return real error codes.

switch.

Don't use stream names, use DAPM to route from the AIF to the widgets.

This is going to mean that you have a symmetry constraint I think, if
you try to set up different rates for playback and capture presumably
things will break.  Setting symmetric_rates will tell applications about
that.

Just have a default.

Braces around the for () too please.

This looks like you need sensible refcounting somewhere?  Implementing
this as the standard PM operations may be sensible.

You should be coming out of cache only mode before you issue the reset
write.  Is it not sensible to skip that if you have a physical reset
line?

Likewise here.  Also if you do reset the CODEC then the dance you did
with the regulator notifiers becomes pointless - the goal with that is
to avoid the need to resync the cache if the CODEC wasn't actually reset
by a power cycle but since the CODEC is going to be explicitly reset
before it's powered off there's no benefit.

Coding style, please.

Replaced with straight forward aic31xx_volatile() and aic31xx_writable() 
functions.

"SP" replaced with "Speaker", also in DAPM switches.

Not with bits, but with regs. I decided this structure would be easier 
to implement and understand than having a switch(w->reg) with nested 
switch(w->shift) cases. I replaced the string comparisons with a single 
switch case using a binary combination of w->reg and w->shift.

Renamed DAC stnames to "Left Playback" and "Right Playback".

Not really. This was just avoid power on sequence when bias level goes 
from SND_SOC_BIAS_PREPARE back to SND_SOC_BIAS_STANDBY. I'll change this 
to a "if (codec->dapm.bias_level == SND_SOC_BIAS_OFF)" in set_bias_level 
like other codecs do.

I rewrote the bias-level/power logic a bit. It should now look more like 
the other codecs. I hope you like this version better.

Removed the redundant badly indented comments.

Fixed also the Kconfig and Makefile ordering and added dt-include for 
micbias and changed the default to 2.0V. All are now squashed to a 
single patch.

In addition to addressing your comments I also added an internal ADC 
input and DAC output for codec to turn on at playback/capture start even 
if the alsamixers are not set correctly.

I'll mail the patches shortly.

Best regards,
Jyri
