The patch exposes the available i2c busses on the PowerNV platform
to the kernel and implements the bus driver to support i2c and
smbus commands.
The driver uses the platform device infrastructure to probe the busses
on the platform and registers them with the i2c driver framework.

This had major conflicts in the above files.
I've fixed it up but please check I did it correctly:
https://github.com/mpe/powerpc-merge/commits/pw/neelesh-i2c
It also doesn't build as a module:
$ grep CONFIG_I2C_OPAL .config
CONFIG_I2C_OPAL=m
$ make ...
...
ERROR: "opal_i2c_request" [drivers/i2c/busses/i2c-opal.ko] undefined!
Right that needs to be exported, however for those OPAL wrappers to work
when exported as modules on an LE kernel with ABI v2 (pfiew !) we need
another patch from jk to sort out the external entry to the asm...
Jeremy, is that already in or not yet ?
Yeah it's been in since October.
Please send a v4 with a fix for this Neelesh.
cheers
