Use the form "ti,omap4-*", etc.
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.
