Hi!
Sorry for not sending this from my axentia.se account, but I tend to
get high spam-scores from there when I use git send-email.
This is a new driver, and it's pretty minimalistic with support for
only a few basic controls. However, it is usable and I'd be happy
to see it included.
I don't know if it's presumptious to add myself as a maintainer, but
checkpatch complained...
Are the alsa control names wisely chosen?
Please review!
Cheers,
Peter

I don't know if you already tried it, but I had the same issue until I
switched from sendmail to actually using an smtp server in the
git-send-mail config.

Is there any specific reason why this is separate and not part of the
initial patch?

I'm not sure I like this macro. Just using snd_soc_update_bits should make
it easier to review the patch since people understand its sematnics.

This is no longer necessary and won't even build with the latest ASoC tree.

Please don't do stuff like this, it just makes the code look more
obscure than it should be for people who work with multiple devices -
just use update_bits() directly.

Use DAPM to manage power, you're probably looking for a supply widget.

Why does this need to be reset every time, shouldn't we just be setting
the register in set_fmt().?

This is redundant, just remove the entire function - ASoC will get the
regmap automatically.

If the register is volatile it shouldn't have a default value provided.

X Volume, the Gain is redundant.

Thanks for the review! I'm answering here, but would like to thank
Lars-Peter for the review as well.

Ok, I'll zap it. Pity though, I really liked the actual code even if the macro was a
bit hard to digest...

I'll try to find out how to hook that up. BTW, there is very limited info about
the supply widget at http://www.alsa-project.org/main/index.php/DAPM

Yes, I'd sure like to do that, but how do I get to the width in set_fmt()?

Then I misunderstood what volatile was meant to do. I'll just nuke the
function. It works fine anyway...
I'll send a v2 later, with the other bits from Lars-Peter taken care of, and
with 2/2 squashed. Need to test first though...

Oh, this has some width related thing in it?

A volatile register is one that the chip may change autonomously (eg, an
interrupt status register).

Yes, the amp has a different setting for each lsb-justified width.
(It also supports 18 and 20 bits wide data)

That was what I assumed, and the register behaves like that. I naively
thought that declaring it as volatile would prevent the asoc core from
writing to it. In retrospect, I don't understand why I thought that...
Anyway, that bit can wait until someone actually needs to read the staus.
Here's an update with the following changes since v1:
- squashed patch 2/2
- zapped the TFA9879_REG macro
- zapped tfa9879_probe (which needlessly registered the regmap)
- moved tfa9879_prepare/_shutdown to a DAPM_SUPPLY widget
- zapped the tfa9879_volatile() thing
- made tfa9879_dai_ops const
- erased the redundant "Gain" from the bass/treble volume controls
- using params_width() instead of params_format()
Cheers,
Peter

The fix here is the wrong way round - if the device is reporting status
here there should be no default and there should be a volatile operation
(though it's not the end of the world to omit that if it's not used).
Otherwise this looks good.
