[31mCONFIG_A[0m serious problem is that there is no documented way to issue

Caution! at91rm9200, at91sam9261, at91sam9260, at91sam9263 devices

you can encounter underrun issues causing premature stop sendings if
the latency to fill the transmission register is too long. If you

tristate "Parallel port adapter"
depends on [31mCONFIG_PARPORT[0m
select [31mCONFIG_I2C_ALGOBIT[0m
select [31mCONFIG_I2C_SMBUS[0m
help
This supports parallel port [31mCONFIG_I2C[0m adapters such as the ones made by
Philips or Velleman, Analog Devices evaluation boards, and more.
Basically any adapter using the parallel port as an [31mCONFIG_I2C[0m bus with
no extra chipset is supported by this driver, or could be.
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.rst for details.
Another driver exists, named i2c-parport-light, which doesn't depend
on the parport driver. This is meant for embedded systems. Don't say
Y here if you intend to say Y or [31mCONFIG_M[0m there.
This support is also available as a module. If so, the module
will be called i2c-parport.

help
This supports parallel port [31mCONFIG_I2C[0m adapters such as the ones made by
Philips or Velleman, Analog Devices evaluation boards, and more.
Basically any adapter using the parallel port as an [31mCONFIG_I2C[0m 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 [31mCONFIG_M[0m to i2c-parport. Saying [31mCONFIG_M[0m to
both is possible but both modules should not be loaded at the same
time.
This support is also available as a module. If so, the module
will be called i2c-parport-light.

This device is almost undetectable and using this driver on a
