Subject: [PATCH 05/10] ASoC: mediatek: mt8183: Configure shared clocks
Date:   Thu,  8 Sep 2022 12:11:49 -0400
Message-Id: <20220908161154.648557-6-nfraprado@collabora.com>
In-Reply-To: <20220908161154.648557-1-nfraprado@collabora.com>

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
