David Brownell24d0fb42007-10-13 23:56:32 +0200287 This driver is BROKEN because the controller which it uses
288 will easily trigger RX overrun and TX underrun errors. Using
289 low I2C clock rates may partially work around those issues
290 on some systems. Another serious problem is that there is no
291 documented way to issue repeated START conditions, as needed

293 unless your system can cope with those limitations.
