[PATCH v2 10/17] thermal: exynos: dts: Define default thermal-zones for Exynos4

Lukasz Majewski
2014-12-10T12:09:49Z

Trip points corresponding to the one defined in the exynos_tmu_data.c
for Exynos4 have been included.
This thermal-zones attribute is afterwards reused for Exynos4210, Exynos4412
and Exynos5250.
