sounds reasonable - will do it that way.

ok - currently I'm preparing bring up of a MPC8377 based system.
But we have this chips on multiple boards and also on generic PCIe
grabber cards running on any desktop PC.

Since we could use the driver directly after registering the various I2C
masters I'd prefer to go with drivers/misc. After all it's a simple I2C
slave device usable by anyone ...

Will send an initial patch for review after basic verification with real

Thanks for your help.
