[v4,11/17] thermal: exynos: dts: Define default thermal-zones for Exynos4

Commit Message

Lukasz Majewski Jan. 16, 2015, 11:30 a.m. UTC

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.
