Hi,
instead using the FIQ part we can try to use the
w1_bq27000 one wire protocol for 2.6.3x.
What do you think about?

Well, we still need a one wire master. Which would probably
be FIQ based.
The gpio based is not ok or it's too slow? Michel

One wire is similar, but different from hdq, so one would at least
need an hdq gpio driver.
But is ok to try to use some that does't use FIQ, so somenthing
like a gpio bitbang master?
Sure. I would be happy if we could do it without using FIQ.
I expect everyone would - so it worries me a bit that the original
implementation was not done with simple gpio bitbanging. It might not
be a bad idea to ping Andy to understand why he didn't choose the
one-wire. Perhaps the timing still requires the FIQ anyway, or perhaps
there's some other limitation of which we are unaware.
