From e590522a06adce8ca2eb47e77d80616cd1542d91 Mon Sep 17 00:00:00 2001 From: Kirill Marinushkin Date: Wed, 4 Apr 2018 06:19:39 +0200 Subject: ASoC: topology: Add definitions for mclk_direction values Current comment makes not clear the direction of mclk. Previously, similar description caused a misunderstanding for bclk_master and fsync_master. This commit solves the potential confusion the same way it is solved for bclk_master and fsync_master.
