[PATCH 05/10] ASoC: mediatek: mt8183: Configure shared clocks

From: Nícolas F. R. A. Prado
Date: Thu Sep 08 2022 - 12:12:26 EST


i2s0 and i2s5 are paired input/output connected to the same codec and
should share the same clock. Likewise for i2s2 and i2s3. Set the clock
sharing for each pair during the DAI initialization.
