This patch adds lpi2c bus driver to support new i.MX products which use lpi2c instead of the old imx i2c. The lpi2c can continue operating in stop mode when an appropriate clock is available. It is also designed for low CPU overhead with DMA offloading of FIFO register accesses.

This supports parallel port I2C 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 I2C 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 for details.

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

|
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

time.
