I'm using bitbanging i2c driver for an AT91 devices, the AT91 is master and I have a slave that reply, during a write, with a NAK after last byte. The i2c specification permit this solution but i2c linux driver no. (i have see the possibility to set the I2C_M_IGNORE_NAK but ignore all NAK and isn't right!) There is a solution or I have to modify the code? Thank you Michele
