Subject: [TEGRA194_CPUFREQ PATCH v5 2/4] arm64: tegra: Add t194 ccplex compatible and bpmp property
Date: Mon, 13 Jul 2020 19:36:47 +0530 [thread overview]
Message-ID: <1594649209-29394-3-git-send-email-sumitg@nvidia.com> (raw)
In-Reply-To: <1594649209-29394-1-git-send-email-sumitg@nvidia.com>
On Tegra194, data on valid operating points for the CPUs needs to be
queried from BPMP. In T194, there is no node representing CPU complex.
So, add compatible string to the 'cpus' node instead of using dummy
node to bind cpufreq driver. Also, add reference to the BPMP instance
for the CPU complex.
