Xilinx I2C driver for linux 2.6?

Xilinx I2C driver for linux 2.6?

[Jean-Baptiste Maneyrol]

Hi everybody!

Does anyone know if there is somewhere an i2c driver for the Xilinx IIC IP
working on linux 2.6?

I'm using the ML405 board with EDK 8.2i, and their driver is for linux 2.4.

Thanks!

Not afaik. We're using the OpenCores I2C controller instead which I in
the mean time have written a driver for (in mainline). The IP core is
afaik even smaller than the Xilinx controller.

Peter, whats the name of the driver in mainline?
(Denx git or kernel.org?)

I want to use the opencore IP in a memory mapped
FPGA (Altera though), so would like to take a look
at your driver.

Cheers,
Dave

Kernel.org - drivers/i2c/busses/i2c-ocores.c

Also take a look at Documentation/i2c/busses/i2c-ocores.

You're welcome. It should be pretty easy to get going (just provide a
platform device with addr/irq).
