Subject: [PATCH v7 2/7] ASoC: dt-bindings: fsl_asrc: Add new property fsl,asrc-format
Date: Tue, 14 Apr 2020 08:43:04 +0800 [thread overview]
Message-ID: <f952cd0ead3816d0c208891d7c8c3895187394a3.1586747728.git.shengjiu.wang@nxp.com> (raw)

In order to support new EASRC and simplify the code structure,
We decide to share the common structure between them. This bring
a problem that EASRC accept format directly from devicetree, but
ASRC accept width from devicetree.
In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, then driver
can accept format from devicetree, don't need to convert it to
format through width.
