The jacks should correspond to the physical jacks on the system rather than the function so that users and applications can tie the jacks that we have in software to those physically on the system. Now I'm wondering if the headphone and microphone are expected to be a single jack here?

At least the Chromebook version will have a single combo jack.

It's fine to do that in the CODEC driver and actually good for the headphone and microphone - the board can always pass in the same jack for all of them but if it does have split headphone and mic jacks then it can do that.

Thanks. I will post v2 after Bard modifies the api Yang

I will post v2 after Bard modifies the api If I'm interpreting Mark's comment correctly, he is suggesting that the API remain the same and have cht_bsw_rt5645.c pass the same jack to all three parameters. I like this idea, as unlike the 227e driver the 5650 could be used with separate hp and mic jacks. I'd imagine there wouldn't be a button jack in that case since that is headset specific, but that shouldn't matter. > > Yang

Yes, that's what I meant - I had originally interpreted the ability to specify the buttons separately as the ability to turn button detection on or off from the machine driver, either the same as mic or null.
