David Brownell24d0fb422007-10-13 23:56:32 +0200293 This driver is BROKEN because the controller which it uses
294 will easily trigger RX overrun and TX underrun errors. Using
295 low I2C clock rates may partially work around those issues
296 on some systems. Another serious problem is that there is no
297 documented way to issue repeated START conditions, as needed
