[PATCH v2 1/3] ARM: dts: Add cooling levels for CPUs on exynos5420

From: Krzysztof Kozlowski <hidden>
Date: 2016-02-18 05:13:24
Also in: linux-arm-kernel, linux-pm, linux-samsung-soc, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

On Exynos5420 we support 8 cpufreq steps (600-1300 MHz) for LITTLE and
12 steps for big core (700-1800 MHz). Add respective cooling cells.

Signed-off-by: Krzysztof Kozlowski <redacted>

Changes since v1:
1. Add cooling properties to all CPUs (suggested by Viresh).
