We can use interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it. Patches 01, 02, 03 enable interconnect path tag and update the DT binding document; patches 04 and 05 support bucket and use bucket values to set the bandwidth and clock rates. Changes from v3: - Removed $ref and redundant sentence in DT binding document for '#interconnect-cells' (Krzysztof Kozlowski). Changes from v2: - Fixed for DT checker error for command ''make DT_CHECKER_FLAGS=-m dt_binding_check' (Rob Herring). Changes from v1: - Added description for property "#interconnect-cells" (Rob Herring); - Added Dimtry's reviewed tags for patches 02 and 03 (Dmitry Baryshkov); - Rebased on the latest mainline kernel and resolved conflict.
