338 Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices
339 don't have clock stretching in transmission mode. For that reason,

1047 This supports parallel port I2C adapters such as the ones made by
1048 Philips or Velleman, Analog Devices evaluation boards, and more.
1049 Basically any adapter using the parallel port as an I2C bus with
1050 no extra chipset is supported by this driver, or could be.
1051
1052 This driver is a light version of i2c-parport. It doesn't depend
1053 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +02001054 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -07001055 the clean but heavy parport handling is not an option. The
1056 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +02001057 daisy-chain other parallel port devices.
