[v4,08/17] thermal: exynos: dts: Add default definition of the TMU sensor parameter

Commit Message

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

Exynos 4 and 5 family of SoCs uses almost identical TMU sensor to measure the
on chip temperature. For this reason it is possible to group TMU configuration
parameters in one dts file.

Changes for v2:
- None
Changes for v3:
- "samsung,tmu_" prefix for TMU specific properties has been added
Changes for v4:
- None
