 * layout and extra registers.  The ID register in the V2 peripheral
 * unit on the OMAP4430 reports the same ID as the V1 peripheral
 * unit on the OMAP3530, so we must inform the driver which IP
 * version we know it is running on from platform / cpu-specific
 * code using these constants in the hwmod class definition.
