Series Introduce memory interconnect for NVIDIA Tegra SoCs | expand

Commit Message

Dmitry Osipenko Oct. 25, 2020, 10:17 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.
Update board device-trees with optional EMC core supply and remove
unsupported OPPs.

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