Hi, Alan,
I don’t see my I2C virtual bus driver code in the current repo. I’m not sure
what happened, but I’d like to [re-] submit it. Can you point me to how that’s
done today? (I’m sure email won’t work).
The problem I see with the existing IOEXPANDER code is that I don’t believe
it’s thr
Hi David,

Gustavo, all you need to do is use the existing driver. In your code
you was trying to implement a low level driver to communicate with
your PCF8575. You don't need to do it.
Unfortunately there is not much boards examples using IOEXPANDER (sha
Hi, Gustavo,

manage a multi-tiered tree of I2C bus expanders.
The advantages are:
* I2C sub buses are transparently available to application space through
/dev/i2c*
* transparently manages hierarch of I2C bus expan
