Subject: [Patch v3 04/11] memory: tegra: add software mc clients in Tegra234
Date: Mon, 20 Mar 2023 23:54:34 +0530 [thread overview]
Message-ID: <20230320182441.11904-5-sumitg@nvidia.com> (raw)
In-Reply-To: <20230320182441.11904-1-sumitg@nvidia.com>
Add dummy Memory Controller clients to represent CPU clusters.
They will be used by the CPUFREQ driver to scale DRAM FREQ
with the CPU FREQ.
