Sadly not. It was just an idea I had in my mind and some talking with
Mark at FOSDEM. Then priorities changed and I worked on something else.
You might want to look for threads where people implemented 'irqless' or
'polling' i2c transfers. I recall at least one discussion in the last
year, but can't seem to find it now :( Dunno if there is something
worthwhile in there, though.
