    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.

    Kenneth would better be able to clarify how dynamic the SLIMbus is.
