i2c mux: outdated wiki page

i2c mux: outdated wiki page

[Thomas De Schampheleire]

Hi,

Originally, the introduction of the i2c mux mechanism was described on
following wiki page:
https://i2c.wiki.kernel.org/index.php/I2C_bus_multiplexing

It seems that in the mean time, at least some of this code has been
introduced in mainline Linux, and the wiki page is hence pretty
outdated.

Although I understand that a wiki can be edited by anyone, I currently
don't have the full view on which problems still remain, if any.
Therefore I'd like to check with you what the high-level status of the
i2c mux support is.

Thanks,
Thomas

Yes. The I2C subsystem is currently handed over from Jean to me, and I
wanted to ask Jean to update it to the best of his knowledge during the
transition. Just -EBUSY came along...

@Jean: Do you have a few minutes to do this in the near future?

We use it in projects already :)

Thanks for the update.
I may just use it in one of my projects as well :)

Best regards,

Yes, I'm reviewing the wiki right now. Thankfully there's not much
content there so it shouldn't take too much time. And I agree it's a
task for me to complete before I leave, as a matter of fairness.

Wolfram, there's one section for you to update:
https://i2c.wiki.kernel.org/index.php/Linux_2.6_I2C_development_FAQ#Where_do_all_the_patches_go.3F
I described my work flow there, obviously it's out of date now but only
you can tell what it will be from now on.

It's a little late now so I won't have the time to finish with the
wiki, I'll do the rest (basically the multiplexing page) tomorrow.

Yes, the i2c multiplexing code can be considered mature now.

It's done, the wiki is in a good shape again.

Thanks a lot!
