Merge tag 'samsung-dt-devfreq-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/late

Merge "ARM: dts: exynos: Devfreq for v4.7: from Krzysztof Kozłowski:

Topic branch for Device Tree changes adding new generic devfreq driver, for
v4.7:
1. Add bus nodes for Exynos3250, Exynos4x12, Exynos4210 and Exynos542x.
2. Split out common PPMU (Performance Monitoring Unit) nodes into separate
   DTSI. The PPMU provides performance data for devfreq.
3. Add NoCP (Network on Chip Probe) node for Exynos542x. On this SoC, like PPMU
   on older designs, provides performance data for devfreq.
4. Enable DFVS (Dynamic Voltage and Frequency Scaling) on boards:
   - Exynos3250 Rinato,
   - Exynos4412 Odroid-X/X2/U3 and Trats2,
   - Exynos5422 Odroid XU3/XU3-Lite/XU4.
