Subject: [PATCH 06/12] thermal: exynos: remove parsing of
samsung,tmu_reference_voltage property
Since pdata reference_voltage values are SoC (not platform) specific
just move it from platform data to struct exynos_tmu_data instance.
Then remove parsing of samsung,tmu_reference_voltage property.
There should be no functional changes caused by this patch.
