Commit Message

Dmitry Osipenko Nov. 4, 2020, 4:49 p.m. UTC 
Add EMC OPP DVFS/DFS tables and interconnect paths that will be used for
dynamic memory bandwidth scaling based on memory utilization statistics.
Remove unsupported EMC OPPs from board device-trees.

Note that ACTMON watches all memory interconnect paths, but we use a
single CPU-READ interconnect path for driving memory bandwidth, for
simplicity.
