Subject: [PATCH v2] ASoC: dt-bindings: imx-card: Add dsp_a DAI format
Date: Tue, 10 Mar 2026 15:35:22 +0900 [thread overview]
Message-ID: <20260310063522.362545-1-chancel.liu@nxp.com> (raw)
The imx-card machine driver originally supported only codecs operating
in i2s or dsp_b formats. This machine driver can support CS42448 codec
and this codec typically uses dsp_a for its TDM interface. Therefore,
dsp_a format support is required for describing such sound cards in DT.
Update DT bindings to include "dsp_a" in the list of supported DAI
formats.
