    interconnect: Add generic on-chip interconnect API · b41a92ff
    Georgi Djakov authored
    This patch introduces a new API to get requirements and configure the
    interconnect buses across the entire chipset to fit with the current
    demand.
    
    The API is using a consumer/provider-based model, where the providers are
    the interconnect buses and the consumers could be various drivers.
    The consumers request interconnect resources (path) between endpoints and
    set the desired constraints on this data flow path. The providers receive
    requests from consumers and aggregate these requests for all master-slave
    pairs on that path. Then the providers configure each node along the path
    to support a bandwidth that satisfies all bandwidth requests that cross
    through that node. The topology could be complicated and multi-tiered and
    is SoC specific.
