PC87431 is not - need full datasheet.

[mds4@verizon.net (Mark Studebaker)]

thanks for the info about the datasheet requiring an NDA.
Unfortunately this means things will be difficult.
But it may be sufficient just to get KCS over I2C working to it.

The chip uses KCS over I2C.
Corey, can we do that with the IPMI KCS driver? Do we need to
write code to register with the KCS module to route KCS messages
to a particlar address on a particular i2c bus?
How would we do that - or does IPMI already have that capability?

Once that is done, then the standard modules
bmcsensors -> i2c-ipmi -> ipmi-msghdlr -> ipmi_kcs_sm
should work.

right Corey?
