I have added an XPS_IIC core into an existing project, and
do not seem to be able to use the /dev/i2c-0 entry point to access it with my
driver. The devices are there (i2c-0 – i2c-7). I can see the
iic device in /proc/iomem (although there is only one entry here, without an
inset entry like the other devices). # cat iomem 81400000-8140ffff : xilinx_gpio.1 81400000-8140ffff : xilinx_gpio 81410000-8141ffff : xilinx_gpio.3 81410000-8141ffff : xilinx_gpio 81420000-8142ffff : xilinx_gpio.2 81420000-8142ffff : xilinx_gpio 81440000-8144ffff : xilinx_gpio.0 81440000-8144ffff : xilinx_gpio 83000000-8300ffff : xilinx_iic.0 84000000-8400ffff : uartlite.0 84000000-8400000f : uartlite a0000000-a0ffffff : physmap-flash.0 a0000000-a0ffffff : physmap-flash.0 In my kernel configuration I have enabled I2C Support and
I2C device interface. Under I2C Algorithms I have enabled Xilinx IIC
interface. Any suggestions as to what could be going wrong?
