I'll update this per suggestion from @jajanusz. GLK needs only the first commit with feature add. The test topologies for APL are not relevant. |
This patch allows to configure the two DMIC DAIs for different used microphones, e.g. DAI 0 for 4ch and DAI 1 for 2ch capture. The common decimator core is programmed for combined max. request and the FIFOs are configured to match the desired microphones. In case of not a possible configuration an error is returned. The patch also cleans up the magic value of four that was used in determining IPM bit fields setting. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
