Subject: [alsa-devel] [PATCH 5/7] ASoC: amd: add ACP3x TDM mode support
Date: Tue, 1 Oct 2019 06:28:13 +0530 [thread overview]
Message-ID: <1569891524-18875-5-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com> (raw)
In-Reply-To: <1569891524-18875-1-git-send-email-Vishnuvardhanrao.Ravulapati@amd.com>
ACP3x I2S (CPU DAI) can act in normal I2S and TDM modes. Added support
for TDM mode. Desired mode can be selected from ASoC machine driver.
