How has slave-mode support been tested? Remembering that I2C slave devices do not initiate bus accesses, all accesses will be started by some other master. How are you dealing with the bytes received from the master, and how are you returning a response to the master in reply to a read request? We had support for this on PXA I2C through a callback from the driver into PXA code (used for the Psion Teklogix Netbook device) and it worked really well, but what you can't do is use the standard I2C interfaces for slave mode. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
