Or we can use one compatible string, but need add another property "fsl,asrc-clk-map" to distinguish the different clock map.
The change is in below.
Which one do you think is better?
Required properties:
- - compatible : Contains "fsl,imx35-asrc" or "fsl,imx53-asrc". + - compatible : Contains "fsl,imx35-asrc", "fsl,imx53-asrc", + "fsl,imx8qm-asrc".
- reg : Offset and length of the register set for the device.
