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. 13 rarely used. However, it is recommended to use a DMA-safe buffer if your 14 message size is likely applicable for DMA.
