The internal clock mapping is different for each module.
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.
