From 7b5c62dc6c1de58ee1d527059ae69152ed1380f2 Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Mon, 12 Dec 2016 11:52:24 +0800 Subject: [PATCH] MLK-13609: ASoC: fsl_sai: fix for synchronize mode TX synchronous with receiver: the RMR should not be changed and the RCSR.RE should be set in playback. RX synchronous with transmitter: the TMR should not be changed and the TCSR.TE should be set in recording.
