From mboxrd@z Thu Jan 1 00:00:00 1970 From: shawnguo@kernel.org (Shawn Guo) Date: Sat, 17 Jun 2017 22:25:28 +0800 Subject: [PATCH] ASoC: zx-i2s: flip I2S master/slave mode Message-ID: <1497709528-23036-1-git-send-email-shawnguo@kernel.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Shawn Guo The SND_SOC_DAIFMT_MASTER bits are defined to specify the master/slave mode for Codec, not I2S. So the I2S master/slave mode should be flipped according to SND_SOC_DAIFMT_MASTER bits.
