What is the protocol for the I2C_SLAVE_STOP event? I am working on my own
backend, and I've only tried it with this i.mx driver, and I do not receive
I2C_SLAVE_STOP at the end of every I2C transaction. It was my expectation
I'd receive this event at the end of every frame. In my testing, I've never
received this event at all.

Where are the I2C registers on the i.mx documented? My board is an i.mx6sx.

Hmm, from a glimpse, it looks the STOP event is only sent after a write
and not after a read? Does this match your findings?
