Subject[RFC 0/2] get rid of remaining users of attach_adapter
Date
The attach_adapter mechanism of the I2C framework is deprecated for years.
There are two users left, drivers for old Macintosh computers. I recently got
the idea of replacing this mechanism with a custom one with the help of
deferred probing. Because I don't have the hardware, I worked on a seperate
branch where I modified the windtunnel driver to be runnable on my Renesas
Lager board (ARM). I first verified that the attach_adapter method was used,
then the driver rightfully failed on detecting the i2c clients. Using my custom
mechanism, the same happens: all busses get scanned, then the clients cannot be
detected. Since I didn't change the actual detection code, I assume that it
should be working on those Macintosh devices as well. The keywest driver is
only compile-tested. That being said, I'd be more than happy, if we could find
someone willing to test these patches. If they could be applied, we can
_finally_ get rid of this legacy mechanism and clean up the i2c core.

The branch I used for ARM compilation is here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/attach_adapter_removal_with_arm_compile-experimental

Thanks,

Wolfram
