Hi all, I developed a I2C bus driver for Xilinx for that Virtex-II Pro product. The I2C interface is implemented as IP in the FPGA. Xilinx provides OS independent drivers that they encourage using due to the fluid nature of the FPGA implementation. Then an OS dependent driver is crafted to call the OS independent functions. This fit quite well with the I2C adapter/algorithm split. I treated their code as the adapter and wrote an algorithm to sit on top of that. Recently, Xilinx gave their permission to allow the code to be pushed out to public trees. As part of pushing out the support for the platform, I pushed out my initial I2C bus driver into a Linux PowerPC tree: http://ppc.bkbits.net:8080/linuxppc_2_4_devel/src/drivers/i2c/xilinx_iic?nav=index.html|src/.|src/drivers|src/drivers/i2c I am now able to start the process of making it "official", so I am in need of having a couple of IDs reserved: one for the adapter and one for the algorithm. I was thinking that I2C_HW_XILINX and I2C_ALGO_XILINX might make sense. Then I can start working through the rest of the list posted at: http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/developers/new_drivers Let me know if you have any questions/concerns and I'll try to address them.
