Subject: [RFC PATCH v2 06/17] ARM: dts: tegra20: Add CPU Operating Performance Points
Add CPU's Operating Performance Points to the device tree, they are used
by the CPUFreq driver and allow to setup thermal throttling for the boards
by linking the cooling device (CPU) with thermal sensors via thermal-zones
description.
