DMIC API Test ################## This test is designed to verify that DMIC peripherals implement the API correctly. It performs the following checks: * Verify the DMIC will not start sampling before it is configured * Verify the DMIC can sample from one left channel * Verify the DMIC can sample from a stereo L/R pair * Verify that the DMIC works with the maximum number of channels possible (defined based on the DTS compatible present in the build) * Verify that the DMIC can restart sampling after being paused and resumed * Verify that invalid channel maps (R/R pair, non-adjacent channels) are rejected by the DMIC driver.
