Add optional i2c_recover_bus() function to the Synopsys DesignWare I2C
adapter
driver that performs i2c bus recovery after timeout. The scope of this
routine
is to define i2c bus recovery procedure as specified in the i2c protocol
Rev. 03
section 3.16 titled "Bus clear".
What do you do in the function ?
Could we have it in the driver file itself?
I think bus recovery mechanism is to send extra clock on SCL line by
toggling the pin (using gpio apis)
You mean the SCL I didnt understand the gpio part?
Why is gpio needed?
How do you toggle the SCL pin?
