339 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
340 don't have clock stretching in transmission mode. For that reason,
341 you can encounter underrun issues causing premature stop sendings if

1048 This supports parallel port I2C adapters such as the ones made by
1049 Philips or Velleman, Analog Devices evaluation boards, and more.
1050 Basically any adapter using the parallel port as an I2C bus with
1051 no extra chipset is supported by this driver, or could be.
1052
1053 This driver is a light version of i2c-parport. It doesn't depend
1054 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +02001055 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -07001056 the clean but heavy parport handling is not an option. The
1057 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +02001058 daisy-chain other parallel port devices.
