multiplexing support to i2c driver + infrastructure

[ruik]

Incorporate the support for virtual busses.  as found here

This should wait until i2c core is converted to driver model as Jean suggests.

[ticket]

Is there a chance to view this done? This is an active ticket, but there aren't goals in the roadmap

I updated kumar's patch up to the 2.6.20 kernel, but 2.6.22 changes in i2c-core.c are too hard for me!!

I sent a mail to the lkml without replies.

I'm not a programmer, but if right pointed i think i can help in something.

Thanks for your great work!

This ticket doesn't really belong there in the first place (it's not related to sensors). The only place to discuss i2c issues at the moment is the i2c mailing list.

The i2c changes in 2.6.22 are actually what I was waiting for before working on the multiplexing issues. I wanted to make sure that the way we implement multiplexing is compatible with enumerated I2C devices. Where the mux is an I2C device itself, enumerating it is the way to go, too, so the new infrastructure was needed.

My main problem at the moment is that I do not have any device requiring I2C multiplexing, so I can't work actively on this myself. If I had some device to play with, it would definitely be easier and I would be more motivated too.

Sending an updated patch to the i2c list can't hurt, if you want to do this.
