[U-Boot] canyonlands u-boot ibm-iic question
Hopefully this is on topic for this list. I am using the canyonlands with the included u-boot. I've made a change to the kernel so that I can use the iic device (namely added the 460ex to the compatibility list) with a name matching the one in canyonland.dts
It seems to print out when it books Linux, but gives an error as shown here - I am unsure what I need to add to the device tree to get past this point.
ibm-iic 4ef600700.i2c: no index specified ibm-iic: probe of 4ef600700.i2c failed with error -22 ibm-iic 4ef600800.i2c: no index specified ibm-iic: probe of 4ef600800.i2c failed with error -22
SEcondly, and I know this is probably not on-topic, How do you access the I2C from userspace? Or how would I read/write the eeprom?
thank

This is Linux related. And you already posted to linuxppc-dev, which is the correct list.
