Nikolaus Vossfac368a2011-11-08 11:49:46 +0100366 A serious problem is that there is no documented way to issue
367 repeated START conditions for more than two messages, as needed
David Brownell24d0fb422007-10-13 23:56:32 +0200368 to support combined I2C messages. Use the i2c-gpio driver
Nikolaus Vossfac368a2011-11-08 11:49:46 +0100369 unless your system can cope with this limitation.
370
371 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
372 don't have clock stretching in transmission mode. For that reason,
373 you can encounter underrun issues causing premature stop sendings if
374 the latency to fill the transmission register is too long. If you
375 are facing this situation, use the i2c-gpio driver.
