[PATCH v2 4/6] i2c: ensure SDA is released in recovery if SDA is controllable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

If we have a function to control SDA, we should ensure that SDA is not
held down by us. So, release the GPIO in this case.
