This is theoretically true, but IIRC David mentioned that the bus is

Actually, this is a different one than the one I was mentioning at the
Linaro Connect. I believe SLIMbus is more active
http://en.wikipedia.org/wiki/SLIMbus
The other bus I was mentioning is called SSBI, which as far as I know
is only used to communicate between MSMs and certain Qualcomm
peripheral chips.
Thanks for the clarification! I assumed these were the same thing because
the patches were posted just after we had talked about the other one.
Kenneth would better be able to clarify how dynamic the SLIMbus is.
That would definitely be helpful. Also, I'd be very interested to hear
what kind of device probing is available on slimbus. If Mark was
right about devices being discoverable, we need don't need any board
description (dts or hardcoded) but instead a way to match the devices
to drivers based on their HW ID.

SLIMbus is a MIPI standard bus primarily used for digital audio devices.
The devices on the bus SLIMbus enumerate themselves by sending an
IDENTITY message. I'll let Sagar clarify further.
thanks,
Ken
