From ba2103467794645e43d8115bef6f4fd18a40b47b Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Tue, 24 Jan 2017 21:49:07 +0530 Subject: [PATCH] ASoC: Intel: bxt: add channel map support in bxt_da7219_max98357a machine HDMI registers channel map controls per PCM. As PCMs are not registered during dai_link init callback, store the pcm ids and codec DAIs during this init callback. Register for late probe and call the jack_init API which also registers channel map in the late probe callback handler.
