Here's a patch against current lmsensors CVS which updates i2c-keywest
to the latest version needed on powermac. It's already in Marcelo as
one of the 2.4.18-pre's.
You may note that the i2c "mode" isn't what it should be to match
exactly what linux-i2c expects (see explaining comment). I will have
to define new transfer types in order to work around that, but it's
ok to do that now as we use this driver only for the sound chip
for now.
Ben.

apparently using these days. At least it's claimed to work partially.
Here's the info:

It may be very close or very far from working. At this point, scanning a
bus gives a bunch of errors, but seems to do different things around
addresses which could very well have devices, so it seems promising.
Hopefully, it's just something silly I'm missing like an 'ack'.
Pretty good for not having *any* technical documentation on the driver,
except a partially written (and maybe not even working) example code
from Apple.

what there is now. What's left is to use the registers of the keywest
to communicate with devices on the bus. (I.e., flesh out the 'access'
routine.)

commit, the module can detect and read the registers from compatible
Keywest buss(es). (Note: there may be more than one bus, as I seem to have.)
Probing is done via Apple's 'New World' Open-Firmware rather than PCI. In
this way, this driver should work with any I2C bus (when it is completed)
which is Keywest 'compatible'. The down side is that this module won't
work on anything but a newer Apple PPC.
