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".

Are the blocks different in some way?

If not, why do you need to distinguish them?

In order to support the two asrc modules in imx8qm, we need to
add compatible string "fsl,imx8qm-asrc0" and "fsl,imx8qm-asrc1"
