ASoC: rt711-sdca: add GE selected mode control

[shumingfan]

ASoC: rt711-sdca: add GE selected mode control This patch adds the 'selected mode' control which overrides the detected_mode.

[fredoh9]

@fredoh9 @marc-hb can you try to see if this patch improve the alsa-bat results with the option options snd_soc_rt711_sdca detected_mode=5

I can quickly test with this today. Will update soon.

[fredoh9]

I was able to test with this PR and the module param.

options snd_soc_rt711_sdca detected_mode=5

Looks detected_mode is consistent throughout multiple tests, however test results have more failure than pass. Captured wave file has very low volume, not even tell whether it's sinewave. Still looking at it. i.e increasing gain. Will update.

Headset Mic Jack also stays ON.

Headset Mic Jack also stays ON.

From the narrow perspective of this PR, this is a PASS! We can discuss and debug alsabat and other issues elsewhere.

Could you test basic, manual hotplug with a sample of headphones and headsets? evtest is the most convenient for this.

[marc-hb]

I had the idea of using an alsa control but the module parameter is fine to start testing.

A module parameter will be less flexible and less convenient for testing automation.

[shumingfan]

@marc-hb @plbossart I will update the patch, creating an alsa control to change the jack type.

[shumingfan]

Can you send to Mark Brown, maybe with an updated commit message such as:

Sure, will send the patch soon.

[plbossart]

shared upstream, thanks @shumingfan

[marc-hb]

@plbossart don't we need this in this branch already to unblock investigation of other capture issues?

[plbossart]

good point @marc-hb. I was planning to pick it up at the next merge, but that merge might be a ways off since we have nothing to send. I'll merge it to topic/sof-dev.
