80 This supports the use of the I2C interface on Atmel AT91

82
83 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
