Paul Mundt 4ad48e6ab1 i2c: Renesas Highlander FPGA SMBus support 
This adds support for the SMBus adapter found in the various FPGAs on
the Renesas Highlander platforms. Particularly the R0P7780LC0011RL and
R0P7785LC0011RL FPGAs.

Functionality is fairly restricted, in that only byte and block data
transfers are supported. Normal/fast mode and IRQ/polling are also
supported. Primarily used for various RTCs and thermal sensors.

help
This supports the use of the I2C interface on Atmel AT91
processors.
This driver is BROKEN because the controller which it uses
will easily trigger RX overrun and TX underrun errors. Using
low I2C clock rates may partially work around those issues
on some systems. Another serious problem is that there is no
documented way to issue repeated START conditions, as needed
to support combined I2C messages. Use the i2c-gpio driver
unless your system can cope with those limitations.

This supports parallel port I2C adapters such as the ones made by

Basically any adapter using the parallel port as an I2C bus with

This driver is a replacement for (and was inspired by) an older
driver named i2c-philips-par. The new driver supports more devices,
and makes it easier to add support for new devices.
An adapter type parameter is now mandatory. Please read the file
Documentation/i2c/busses/i2c-parport for details.

This supports parallel port I2C adapters such as the ones made by

Basically any adapter using the parallel port as an I2C bus with
no extra chipset is supported by this driver, or could be.
This driver is a light version of i2c-parport. It doesn't depend
on the parport driver, and uses direct I/O access instead. This
might be preferred on embedded systems where wasting memory for
the clean but heavy parport handling is not an option. The
drawback is a reduced portability and the impossibility to
daisy-chain other parallel port devices.
Don't say Y here if you said Y or M to i2c-parport. Saying M to
both is possible but both modules should not be loaded at the same
