Add support for the AMD SB800 Family series of products.
Major changes include the changes to addressing the SMBus registers at different
location from the locations in the previous compatible parts from AMD such as
SB400/SB600/SB700. For SB800, the main features and register definitions of
SMBus and other interfaces are still compatible with the previous products with
the only change being in how to access the internal registers for these blocks.

We now timeout also if the state machine does not change within the
given time. For that, the driver-specific completion-functions are
extended to return true or false depending on the timeout. This then
gets checked in the algorithm.

Waiting for a free bus now accepts the timeout value in jiffies and does

According to kerneljanitors todo list all printk calls (beginning
a new line) should have an according KERN_* constant.
Those are the changes to the debug macros in the i2c subsystem
to meet this requirement. Also changing no-debug statements
to raw printks again.

Properly set the adapter timeout value in jiffies, and then use that
value in the driver, rather than a hard-coded constant.

i2c_adapter.timeout is in jiffies. Fix all drivers which thought
otherwise. It didn't really matter as long as the value was only used
inside the driver, but soon i2c-core will use it too so it must have
the proper unit.
Note: for the i2c-mpc driver, this fixes a bug in polling mode.
Timeout would trigger after 1 jiffy, which is most probably not what
the author wanted.

Setting a default timeout value on a per-algo basis doesn't make any
sense. Move the default value setting to i2c-core. Individual adapter
drivers can specify a different (non-zero) value if they wish.
Also express the timeout value in a way which results in the same
duration regarless of the value of HZ.

With a postfix decrement these timeouts reach -1 rather than 0, but after the
loop it is tested whether they have become 0.
As pointed out by Jean Delvare, the msg_num should be tested before the timeout.
With the current order, you could exit with a timeout error while all the
messages were successfully transferred.

The MCP78S and MCP79 appear to be compatible with the previous nForce

The automatic removal of i2c clients only affects the clients which

On popular demand, here comes some documentation about how to
instantiate i2c devices in the new (standard) i2c device driver
binding model.
I have also clarified how the class bitfield lets driver authors
control which buses are probed in the auto-detect case, and warned
more loudly against the abuse of this method.
