Subject: [PATCH] ASoC: mediatek: mt8192: fix register configuration for tdm
Date: Thu, 09 May 2024 07:31:29 +0000 [thread overview]
Message-ID: <20240509-8192-tdm-v1-1-530b54645763@chromium.org> (raw)
For DSP_A, data is a BCK cycle behind LRCK trigger edge. For DSP_B, this
delay doesn't exist. Fix the delay configuration to match the standard.
Fixes: 52fcd65414abfc ("ASoC: mediatek: mt8192: support tdm in platform driver")
