Subject: [PATCH v8 25/26] ARM: tegra: Add DVFS properties to Tegra30 EMC and ACTMON device-tree nodes
Date: Wed, 11 Nov 2020 04:14:55 +0300	[thread overview]
Message-ID: <20201111011456.7875-26-digetx@gmail.com> (raw)
In-Reply-To: <20201111011456.7875-1-digetx@gmail.com>

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.
