From 5011454ee34a84700e9a8c7eb1138efceea9d662 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 17 Apr 2019 14:31:40 +0300 Subject: [PATCH] ASoC: pcm3168a: Enable TDM support for DSP_A/B modes The 24-bit TDM mode also applies to DSP_A and DSP_B modes. Most dais on the SoC side can not interpret I2S/Left_j with other than 2 channels of audio.
