Subject: [TEGRA194_CPUFREQ PATCH v4 1/4] dt-bindings: arm: Add t194 ccplex compatible and bpmp property
Date: Fri, 26 Jun 2020 21:13:53 +0530 [thread overview]
Message-ID: <1593186236-12760-2-git-send-email-sumitg@nvidia.com> (raw)
In-Reply-To: <1593186236-12760-1-git-send-email-sumitg@nvidia.com>
To do frequency scaling on all CPUs within T194 CPU Complex, we need
to query BPMP for data on valid operating points. Document a compatible
string under 'cpus' node to represent the CPU Complex for binding drivers
like cpufreq which don't have their node or CPU Complex node to bind to.
Also, document a property to point to the BPMP device that can be queried
for all CPUs.
