From 23607025303af6e84bc2cd4cabe89c21f6a22a3f Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Fri, 17 Jan 2014 17:03:55 +0000 Subject: ASoC: DPCM: make some DPCM API calls non static for compressed usage The ASoC compressed code needs to call the internal DPCM APIs in order to dynamically route compressed data to different DAIs.

Some DSPs can route compressed data to multiple BE DAIs like they do for PCM data. Add support to allow dynamically routed compressed streams using the existing DPCM infrastructure. This patch adds special FE versions of the compressed ops that work out the runtime routing.
