[PATCH 16/21] thermal: exynos: dts: Provide device tree bindings identical to one in exynos_tmu_data.c

Lukasz Majewski l.majewski at samsung.com
Thu Oct 9 09:38:52 PDT 2014


Presented device tree bindings provide data already hardcoded in the
exynos_tmu_data.c file.
After this commit, it should be possible to reuse common thermal core
framework in Exynos SoCs.
