ASoC: Intel: Skylake: Update DMIC DAIs and capabilities
On Skylake we can support upton 4DMICs on the PDM port, so update the PCM capabilities accordingly Also add a new DAI for DMIC pin which can be used for getting raw DMIC data Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Dharageswari.R <dharageswari.r@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
