    slimbus: Add SLIMbus bus type · 3648e78e
    Sagar Dharia authored
    SLIMbus (Serial Low Power Interchip Media Bus) is a specification
    developed by MIPI (Mobile Industry Processor Interface) alliance.
    SLIMbus is a 2-wire implementation, which is used to communicate with
    peripheral components like audio-codec.
    SLIMbus uses Time-Division-Multiplexing to accommodate multiple data
    channels, and control channel. Control channel has messages to do
    device-enumeration, messages to send/receive control-data to/from
    SLIMbus devices, messages for port/channel management, and messages to
    do bandwidth allocation.
    The framework supports multiple instances of the bus (1 controller per
    bus), and multiple slave devices per controller.
    
    This patch adds support to basic silmbus core which includes support to
    SLIMbus type, slimbus device registeration and some basic data structures.
