Subject: [PATCH 09/10] ASoC: mediatek: mt8186: Configure shared clocks
Date:   Thu,  8 Sep 2022 12:11:53 -0400
Message-Id: <20220908161154.648557-10-nfraprado@collabora.com>

Precedence: bulk

i2s0 and i2s1 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 codec's initialization.
