David Brownell24d0fb42007-10-13 23:56:32 +0200290 This driver is BROKEN because the controller which it uses
291 will easily trigger RX overrun and TX underrun errors. Using
292 low I2C clock rates may partially work around those issues
293 on some systems. Another serious problem is that there is no
294 documented way to issue repeated START conditions, as needed
295 to support combined I2C messages. Use the i2c-gpio driver
296 unless your system can cope with those limitations.
