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

1050 This driver is a light version of i2c-parport. It doesn't depend
1051 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +02001052 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -07001053 the clean but heavy parport handling is not an option. The
1054 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +02001055 daisy-chain other parallel port devices.
