 7 * Version 2 of the I2C peripheral unit has a different register

 9 * unit on the OMAP4430 reports the same ID as the V1 peripheral
10 * unit on the OMAP3530, so we must inform the driver which IP
11 * version we know it is running on from platform / cpu-specific
12 * code using these constants in the hwmod class definition.
