[PATCH 08/10] dt-bindings: memory: tegra210: Mark EMC as cooling device

[Thierry Reding <thierry.reding@kernel.org>]

From: Thierry Reding <treding@nvidia.com>

The external memory controller found on Tegra210 can use throttling of
the EMC frequency in order to reduce the memory chip temperature. Mark
the memory controller as a cooling device to take advantage of this
functionality.
