After a transfer timeout, some faulty I2C slave devices might hold down the SDA pin. We can generate a bus clear command, hoping that the slave might release the pins. If the CLEAR command is not supported, we will use gpio recovery, if available, to reset the bus. Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@microchip.com>
Applied to for-next, thanks!
