Yep, fully agree. In fact Felipe's suggestion was something like 
drivers/ocd for off-chip devices, but maybe something like drivers/gpbus 
will highlight a little bit more the bus controller aspect of such driver.

Yep, fully agree. In fact Felipe's suggestion was something like 
drivers/ocd for off-chip devices, but maybe something like drivers/gpbus
