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
