54 tristate "SMBus multiplexing on the Tyan S4882"
55 depends on I2C_AMD756 && EXPERIMENTAL
57 Enabling this option will add specific SMBus support for the Tyan
58 S4882 motherboard. On this 4-CPU board, the SMBus is multiplexed

77 tristate "Atmel AT91 I2C Two-Wire interface (TWI)"
78 depends on ARCH_AT91 && EXPERIMENTAL && BROKEN
80 This supports the use of the I2C interface on Atmel AT91
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
89 unless your system can cope with those limitations.

296 built-in I2C interface on the MPC107/Tsi107/MPC8240/MPC8245 and
297 MPC85xx/MPC8641 family processors. The driver may also work on 52xx
298 family processors, though interrupts are known not to work.
300 This driver can also be built as a module. If so, the module
301 will be called i2c-mpc.
304 tristate "Nvidia nForce2, nForce3 and nForce4"

340 Philips or Velleman, Analog Devices evaluation boards, and more.
341 Basically any adapter using the parallel port as an I2C bus with
342 no extra chipset is supported by this driver, or could be.
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.

367 This driver is a light version of i2c-parport. It doesn't depend
368 on the parport driver, and uses direct I/O access instead. This
369 might be preferred on embedded systems where wasting memory for
370 the clean but heavy parport handling is not an option. The
371 drawback is a reduced portability and the impossibility to
372 daisy-chain other parallel port devices.
374 Don't say Y here if you said Y or M to i2c-parport. Saying M to
375 both is possible but both modules should not be loaded at the same
