From c997a92a78161af605b314cbe6cf636663999652 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Wed, 22 Nov 2017 00:55:14 +0100 Subject: [PATCH] ASoC: fsl_ssi: call _fsl_ssi_set_dai_fmt() just once in AC'97 mode In AC'97 mode we configure and start SSI RX / TX on probe path via a call to _fsl_ssi_set_dai_fmt() function. We don't need to call this function again later and in fact don't want to do it since this function temporarily sets STCR, SRCR and SCR to some intermediate values. Signed-off-by: Maciej S.
