Yes, ti,am654-icss-iep is for am654. You are right, the compatibles should be
specific to SoC. Currently the upstream support is being added for only AM65x.

I will remove J721E and AM64x SoCs from the comment above and these compatibles
when their support is enabled in future.

Below is the updated compatible property.

properties:
compatible:
enum:
- ti,am654-icss-iep # for K3 AM65x SoCs
