ISL Compatibility between Nexus 5596 & MDS 9148 switch

We want to set-up ISL between Nexus 5596 and Cisco MDS 9148 switches.

Nexus switches are running at 6.0(2)N2(1) whereas MDS 9148 switches will be new.

If someone can provide link for firmware compatibility, then we can upgrade MDS 9148 switches to required level.
