[alsa-devel] NXP Semiconductors TFA9879 Amplifier Driver
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

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.

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

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...

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)

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

Ok, I think I finally see what you mean...

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

Like Lars suggested just squash this into the previous patch.
- SOC_SINGLE_TLV("Treble Gain Volume", TFA9879_BASS_TREBLE,
TFA9879_G_TRBLE_SHIFT, 18, 0, tb_gain_tlv),- SOC_SINGLE_TLV("Bass Gain Volume", TFA9879_BASS_TREBLE,
TFA9879_G_BASS_SHIFT, 18, 0, tb_gain_tlv),
X Volume, the Gain is redundant.

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.
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.
