DBUS interface documentation

[Jeremy Kerr]

Hi all,

We're building up quite a collection of dbus interfaces for OpenBMC, but 
our interface documentation is disappointingly sparse:

   https://github.com/openbmc/docs/blob/master/dbus-interfaces.md

If you've implemented (or are implementing) a DBUS API, could you also 
submit a pull request to update this document with the new API?

This will also allow us to have a bit of a review of the new interfaces 
before they're committed.

Regards,


Jeremy
