I recently ported the mcf_i2c_gpio bus driver to kernel 2.6 (anyone
interested in patches? Where should I send them?).
All the I2C docs say that you're supposed to see information about I2C
busses and devices in /proc/bus/i2c, but it seems to be strangely blank
(in fact /proc/bus is empty).
Currently I don't have any I2C device drivers installed -- I'm just
using the dev interface and the userland i2ctool (which I also ported to
2.6). That seems to work ok via /dev/i2c0. But I'm worried that if I
start adding some device drivers it will start consuming I2C minor
numbers without telling me what is getting assigned where (which is what
I think /proc/bus/i2c is for, isn't it?). So how do I get this to show
