Merge tag 'samsung-dt64-4.5' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt64
Samsung DeviceTree ARM64 updates and improvements for 4.5:
1. Add S2MPS15 PMIC node to Espresso board. This gives proper
control over regulators, provides 32KHz clocks and RTC driver.
2. Enable HS200 mode operation on Espresso board for MMC0.
3. Add reboot capability (generic syscon-reboot).
* tag 'samsung-dt64-4.5' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
arm64: dts: Add reboot node for exynos7
arm64: dts: Enable HS200 mode operation on exynos7-espresso
arm64: dts: Add S2MPS15 PMIC node on exynos7-espresso
