SL261x DMIC feature is added in 2.1, need to wait for QA's test report.

Will all three 261x support this?

Confirm with SQA, this function can't work as there are pinmux change not added, so, we can mark it as 'N/A' for all 3 of 261x.

Discussed with SQA, they didn't find QtCamera application, they will discuss with R&D and confirm in RC-2 testing.

OK, I will wait for RC-2 to see if it needs to be removed.
