From 8a7ec532537c3cbeae5ce5346375cadb7d5be105 Mon Sep 17 00:00:00 2001

Subject: [PATCH 50/60] ASoC: SDP4430: Set the pmdown_time for OMAP_ABE_BE_PDM_DL2
commit 322c58525be4fe472002812f02e9944bec4571c4 upstream
For HF playback stream pmdown_time was not set to 500ms,
5000ms was used as a default delay, which was causing
pops at the end of audio rendering because playback streams
were powered down after McPDM shutdown.
