This is what I was thinking, except that on OMAP2420 the names are:
+	{ .name = "dsp", .irq = 26, },
+	{ .name = "iva", .irq = 34, },

and on OMAP2430 and OMAP3
+	{ .name = "dsp", .irq = 26, },

so why is it named "mbox" on OMAP4?

If you have to do several platform_get_irq_byname to get this one, I'd 
prefer to get rid of that name for OMAP4. It will make mailbox irq 
consistent with the other hwmods.

Thanks,
Benoit
