+* TI - IVA (Imaging and Video Accelerator) subsystem
+
+The IVA contain various audio, video or imaging HW accelerator
+depending of the version.
+
+Required properties:
+- compatible : Should be:
+ - "ti,ivahd", "ti,iva" for OMAP4
+ - "ti,iva2", "ti,iva" for OMAP3
+ - "ti,iva1", "ti,iva" for OMAP2
Again, be specific to the instantiation and encode the omap version
into the compatible value. 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.
