[PATCH 06/21] thermal: exynos: Provide thermal_exynos.h file to be included in device tree files

Lukasz Majewski
2014-10-09T16:39:34Z

This patch is a preparatory patch for being able to read Exynos thermal
configuration from the device tree.

The DTC is not able to interpret enums properly and hence it is necessary
to #define those values explicitly.
