David Brownell24d0fb42007-10-13 23:56:32 +020083 This driver is BROKEN because the controller which it uses
84 will easily trigger RX overrun and TX underrun errors. Using
85 low I2C clock rates may partially work around those issues
86 on some systems. Another serious problem is that there is no
87 documented way to issue repeated START conditions, as needed
88 to support combined I2C messages. Use the i2c-gpio driver
89 unless your system can cope with those limitations.

344 This driver is a replacement for (and was inspired by) an older
345 driver named i2c-philips-par. The new driver supports more devices,
346 and makes it easier to add support for new devices.
