Subject: [PATCH v5 0/2] arm64: dts: exynos: Add E850-96 board support

WinLink's E850-96 is a dev board based on Exynos850 SoC [1]. The board's
design follows 96boards specifications, hence it's compatible with
96boards mezzanines [2].

This patch series adds the initial support for E850-96 board and
Exynos850 SoC. Only basic platform components are enabled at the moment
(like serial, I2C, eMMC, RTC, WDT, clock driver, etc). Right now with
this patch series it's possible to run the kernel with BusyBox rootfs as
a RAM disk. More features are coming soon.

Changes in v5:
  - Excluded applied patches from the series
  - Defined clock binding constants in SoC DTSI file to workaround the
    missing patches in Krzysztof's tree

Changes in v4:
  - Removed slew_rate pin nodes
  - Moved rtcclk clock to board dts file

Changes in v3:
  - Ordered the pinctrl_alive phandle alphabetically (patch 7/7)
  - No other changes in v3

Changes in v2:
  - Rebased on krzk/linux.git (for-next), to account for Exynos7885
    changes
  - Added missing and new tags (R-b and Ack)
  - Addressed all comments for v1
