Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

Pull "Samsung DTS ARM changes for 4.15" from Krzysztof Kozłowski:
1. Add new board: Hardkernel Odroid HC1.
2. Fix incomplete Odroid-XU3/4 thermal-zones definition leading to
possible overheat if first pair of A7+A15 cores is idle but rest of
CPUs are busy.
3. Add capacity-dmips-mhz properties for CPUs of octa-core SoCs.
4. Add power button to Odroid XU3/4.
5. Improvements in Gscaler, HDMI and Mixer blocks on Exynos5.
6. Add suspend quirk to DWC3 USB controller to fix enumeration of
SuperSpeed devices on Odroid XU4.
7. Add HDMI and MHL to Trats2.
8. Cleanups (redundant properties and nodes).

MFC device can be used without any external hardware dependencies (when
IOMMU is enabled), so it can be enabled by default (like it has been
already done for Exynos 542x platforms). This unifies handling of this
device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still
include exynos-mfc-reserved-memory.dtsi to enable using this device

Pull ARM SoC late DT updates from Arnd Bergmann:
"This is a collection of a few late fixes and other misc stuff that had
dependencies on things being merged from other trees.
The Renesas R-Car power domain handling, and the Nvidia Tegra USB
support both hand notable changes that required changing the DT
binding in a way that only provides compatibility with old DT blobs on
new kernels but not vice versa. As a consequence, the DT changes are
based on top of the driver changes and are now in this branch.
For NXP i.MX and Samsung Exynos, the changes in here depend on other
changes that got merged through the clk maintainer tree"
