In that case, I do not necessarily agree. The IVA is a generic TI IP 
used in various chips. The IP version is well documented in the TRM.

OK, in fact I didn't pick the proper version:-(
It should be:

+  - "ti,ivahd", for OMAP4
+  - "ti,iva2.2", for OMAP3
+  - "ti,iva2.1", for OMAP2430
+  - "ti,iva1", for OMAP2420

But still, no need to rely on OMAP version to identify the IVA version.
