Hi Roland,

The i2c changes look ok, but the order breaks bisection through the series.

Since the changes in pnx4008 are fairly localized, I would suggest merging
all three patches through the i2c tree and reorganizing the changes so
that each change is atomic. I would suggest an order like:

1. fix suspend
2. move contents of mach/i2c.h from pnx4008 and lpc32xx to i2c driver
3. change driver and platform device definitions to use resources instead
   of platform data
4. add support for device tree based probing
