Subject: [GIT PULL] ARM: dts: exynos: Devfreq for v4.7
Hi,
Topic branch with DTS changes for v4.7, adding nodes for new generic
devfreq driver. The devfreq driver will support Exynos3250, 4210, 4212,
4412 and 542x.
This is a long work of Chanwoo Choi, recently merged (including
documentation of bindings) by devfreq maintainer, MyungJoo Ham:
http://permalink.gmane.org/gmane.linux.power-management.general/75599
This pull request includes dependency: changes coming from clk tree
with a clk-v4.7-exynos542x tag.
Below you will find full log. At the end - only commits existing
in my tree.
Best regards,
Krzysztof

ARM: dts: exynos: Add support of Bus frequency using VDD_INT for exynos5422-odroidxu3 (2016-05-03 12:27:52 +0200)
----------------------------------------------------------------
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.
