Hi all,

I was looking into the i2c bus recovery sequence and I was wondering why 
there doesn't seem to be an interface (ioctl/sysfs) that allows a user 
to trigger a recovery sequence.
Is this intentional or would such an interface - if it were to be 
implemented-  be welcome?

many thanks in advance.

jorge

I can't think of a reason why this should be possible. The I2C bus
driver should figure out when things go wrong and do the apropriate
actions. Also, the I2C specs have a clear definition when to use bus
recovery.
