David Brownell24d0fb42007-10-13 23:56:32 +0200270 This driver is BROKEN because the controller which it uses
271 will easily trigger RX overrun and TX underrun errors. Using
272 low I2C clock rates may partially work around those issues
273 on some systems. Another serious problem is that there is no
274 documented way to issue repeated START conditions, as needed
275 to support combined I2C messages. Use the i2c-gpio driver
276 unless your system can cope with those limitations.
