From 467b061f1ac80f323bedb56d20a24f7bc0d2cec5 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Mon, 23 Jul 2018 16:54:03 +0100 Subject: ASoC: core: add support to snd_soc_dai_get_channel_map() On Qualcomm platforms, specifically with SLIMbus interfaced codecs, the codec slim channel numbers are passed to DSP while configuring the slim audio path. Having get_channel_map() would allow dais to share such information across multiple dais.
