Subject: [PATCH v9 2/7] ASoC: dt-bindings: fsl_asrc: Add new property fsl,asrc-format
Date: Thu, 16 Apr 2020 20:25:32 +0800	[thread overview]
Message-ID: <e7acbde4b26a82b674a4091515a219e09f847eac.1587038908.git.shengjiu.wang@nxp.com> (raw)

In-Reply-To: <cover.1587038908.git.shengjiu.wang@nxp.com>

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.
