Nikolaus Vossfac368a2011-11-08 11:49:46 +0100373 A serious problem is that there is no documented way to issue
374 repeated START conditions for more than two messages, as needed
David Brownell24d0fb42007-10-13 23:56:32 +0200375 to support combined I2C messages. Use the i2c-gpio driver
Nikolaus Vossfac368a2011-11-08 11:49:46 +0100376 unless your system can cope with this limitation.
377
378 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
379 don't have clock stretching in transmission mode. For that reason,
380 you can encounter underrun issues causing premature stop sendings if
381 the latency to fill the transmission register is too long. If you
382 are facing this situation, use the i2c-gpio driver.
