H A Ddai-intel.hdiff 7df43911e92aa2137ae77ae60efaa9d6656df3fe Wed Jun 12 19:01:47 CEST 2019 Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> ASoC: SOF: Add DMIC token for unmute gain ramp time

The settling time of DMIC DC level is both platform and used
microphone model specific. The unmute gain ramp is used to conceal
most of the large DC level seen in beginning of capture. This patch
adds into the DMIC DAI IPC struct a new field called unmute_ramp_time
and a new token SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME. The value is the
ramp length in milliseconds (ms).

The ABI minor version is incremented for this backwards compatible
change.
