Nikolaus Vossfac368a2011-11-08 11:49:46 +0100367 A serious problem is that there is no documented way to issue
368 repeated START conditions for more than two messages, as needed
David Brownell24d0fb42007-10-13 23:56:32 +0200369 to support combined I2C messages. Use the i2c-gpio driver
Nikolaus Vossfac368a2011-11-08 11:49:46 +0100370 unless your system can cope with this limitation.
371
372 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
373 don't have clock stretching in transmission mode. For that reason,
374 you can encounter underrun issues causing premature stop sendings if
375 the latency to fill the transmission register is too long. If you
376 are facing this situation, use the i2c-gpio driver.
