5 Given that I2C is a low-speed bus, over which the majority of messages
6 transferred are small, it is not considered a prime user of DMA access. At this
7 time of writing, only 10% of I2C bus master drivers have DMA support
9 DMA for it will likely add more overhead than a plain PIO transfer.
11 Therefore, it is *not* mandatory that the buffer of an I2C message is DMA safe.

14 message size is likely applicable for DMA. Most drivers have this threshold
