[alsa-devel] [PATCH 1/5] ASoC: Add ADAU1X61 and ADAU1X81 CODECs common code
The ADAU1X61 and ADAU1X81 are very similar in the digital domain, but are quite different in the analog domain. This patch adds support for the common parts of the ADAU1X61 and ADAU1X81 CODECs.

This patch adds support for the Analog Devices ADAU1361 and ADAU1761 CODECs. The device is a a low-power, 24-bit stereo audio CODEC with multiple analog input and outputs, one digital microphone input and an I2S interface. The device can be controlled either via I2C or SPI. The main difference between the two variants is that the ADAU1761 has a built-in SigmaDSP, while the ADAU1361 has not.

Not a requirement and perhaps it has no effect but these seem like they ought to integrate with the bias level configuration - since only the clocks seem to be managed by set_bias_level() the driver could presumably save a bit of power by dropping down to the minimal power consumption bias while the device is idle. This is what the STANDBY to ON transition is all about.

Why is this a user visible control and not using the jack detection framework support?

Hm, I'm not sure if it makes a difference since all the components have individual power control bits that are managed by DAPM. I would expect the bias current setting to only make a difference if the component is actually powered up. I'll check with the designers, but I think this can still be improved later on if it turns out that it saves power.

The CODEC unfortunately does not support reporting the jack state. All it can do is mute the speaker output in hardware if something is plugged into the headphone jack. The switch allows the users to control whether the output should be auto-muted or not.

Given that the device has non-capless headphone outputs I'd expect there's something being maintained normally, though it's possible that it's still ground referenced.

In that case it should be called something like "Speaker Automute Switch" or similar. It's a bit unfortuante that there's not even any readback for the function.
This patch adds support for the Analog Devices ADAU1381 and ADAU1781 audio CODECs. The device is a low-power, 24-bit stereo audio CODEC with multiple analog inputs and outputs, two digital microphone inputs and an I2S interface. The device can be controlled either using I2C or SPI. The main difference between the two variants is that the ADAU1781 has a freely programmable SigmaDSP processor, while the ADAU1381 has a fixed function wind noise reduction filter.

When would a machine driver use this (as opposed to just letting it be set by platform data)?

I think this is eminently sensible but it seems like it should be a framework feature. That'd have to enable an actual AIF slot though which is a bit fun, which slot do we enable for example?
It would be nice if this could be handled by the core. But how? One option might be tracking the the DAI format in the core and power up the DAI widget in DAPM if the stream is active regardless of if there is an active path if the DAI is in master mode. That may power up more than what is needed though. E.g. for this CODEC the clock generator and the rest of the DAI can be powered up independently and we only need to power up the clock generator.

Setting the relationship between the external clock rate and the internal base sample rate. There might be a better way to do this though.

It is not meant to be used by machine drivers, but by the adau1761 and adau1781 CODEC drivers, which set the micbias based on platform data.
Thanks for the fast review, - Lars

Yes, that was what I was thinking of. We can provide a mechanism to allow the driver to specify a specific widget for the clocks if one exists and fall back on the DAI widgets otherwise.

If it's specifying two clock rates then specifying them both as actual rates might make sense. I take it it's not possible for the driver to automatically figure out what the most sensible rate is?

Ah, in that case how about having generic platform data for the core and just passing that through to a platform data parsing function?
