[PATCH V3 1/2] ASoC: dt-bindings: fsl_asrc: add compatible string for imx8qm

From: Shengjiu Wang
Date: Mon Nov 11 2019 - 04:20:18 EST


Add compatible string "fsl,imx8qm-asrc" for imx8qm platform.

There are two asrc modules in imx8qm, the clock mapping is
different for each other, so add new property "fsl,asrc-clk-map"
to distinguish them.
