From 35dec697579459983e3471b622f57c18f6e9fd0a Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 14 Oct 2011 14:43:34 +0300 Subject: ASoC: twl6040: Request core to inline the DAPM sequence We need to have as less time between McPDM shutdown, and power down of the DAC on the twl6040 codec as possible. Request core to ignore the pmdown_time for the playback stream. Backround: with the McPDM protocol we are sendning not only the pure audio stream, but OMAP McPDM also transmits additional information (for example offset cancellation). If McPDM is stopped prior to the DAC this information will be not sent to the codec, which can result noise rendered by the twl6040 codec.
