[PATCH] ARM: exynos_defconfig: Enable cpufreq-dt driver

Show all headers | View raw

With the latest patches the cpufreq-dt can be used on multiple
Exynos SoCs: 3250, 4210, 4212, 4412 and 5250.

Enable it along with default ondemand governor to conserve the energy,
reduce temperature while maintaining acceptable performance.
