i2c: microchip: fix erroneous late ack send

2022-11-14T06:21:58Z

A late ack is currently being sent at the end of a transfer due to incorrect logic in mchp_corei2c_empty_rx(). Currently the Assert Ack bit is being written to the controller's control reg after the last byte has been received, causing it to sent another byte with the ack. Instead, the AA flag should be written to the control register when the penultimate byte is read so it is sent out for the last byte.

2022-11-14T06:20:10Z

"Master receive mode" was not correctly sending ACKs/NACKs in the interrupt handler. Bring the handling of M_SLAR_ACK, M_RX_DATA_ACKED & M_RX_DATA_NACKED in line with the Linux driver.

i2c: stm32: do not set the STOP condition on error

2022-09-15T12:59:22Z

Current function stm32_i2c_message_xfer is sending a STOP whatever the result of the transaction is. This can cause issues such as making the bus busy since the controller itself is already sending automatically a STOP when a NACK is generated. Thanks to Jorge Ramirez-Ortiz for diagnosing and proposing a first fix for this.
