From 881741fa447d56751fe6f5af66a5c3cae4140903 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Mon, 23 Nov 2020 03:27:22 +0300 Subject: ARM: tegra: Add EMC OPP and ICC properties to Tegra30 EMC and ACTMON device-tree nodes Add EMC OPP tables and interconnect paths that will be used for dynamic memory bandwidth scaling based on memory utilization statistics. Update board device-trees by removing unsupported EMC OPPs. Note that ACTMON watches all memory interconnect paths, but we use a single CPU-READ interconnect path for driving memory bandwidth, for simplicity.
