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 version slightly modified removes the unrelated gunk in opal.c
(but needs to apply on top of some other patches in the powerpc tree)

The driver is the same, it's only the
arch/powerpc/platform/powernv/opal.c init bits that get cleaned up and
simplified.

Subject: [PATCH v2] i2c: Driver to expose PowerNV platform i2c busses

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.

If the devices are found on the device tree for a given bus/adapter,
the platform init code registers them to the core and binds them
a static bus/adapter number, otherwise the driver registers the
adapter to get the adapter number dynamically.

So the driver part depends on the arch/powerpc changes.

I added Wolfram the i2c maintainer to CC. Wolfram are you happy if we take this
through the powerpc tree with your ack, or I can do a topic branch?
