[PATCH 3/3] i2c-omap: Enable workaround for Errata 1.153 based on

2009-08-20 Thread Moiz Sonasath 
Silicon Errata 1.153 has been fixed on OMAP 3630|4430 with the use of a later
version of I2C IP block.

The errata impacts OMAP 2420|2430|3430, enable the workaround for these based 
on I2C IP block revision number instead of OMAP CPU type
