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

1030 This driver is a replacement for (and was inspired by) an older
1031 driver named i2c-philips-par. The new driver supports more devices,
1032 and makes it easier to add support for new devices.

1050 Philips or Velleman, Analog Devices evaluation boards, and more.

1054 This driver is a light version of i2c-parport. It doesn't depend
1055 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +02001056 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -07001057 the clean but heavy parport handling is not an option. The
1058 drawback is a reduced portability and the impossibility to
