Subject: [PATCH v4 0/7] 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, along with corresponding bindings. 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 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

Sam Protsenko (7):
  dt-bindings: clock: exynos850: Add bindings for Exynos850 sysreg
    clocks
  clk: samsung: exynos850: Add missing sysreg clocks
  dt-bindings: Add vendor prefix for WinLink
  dt-bindings: arm: samsung: Document E850-96 board binding
  dt-bindings: pinctrl: samsung: Add pin drive definitions for Exynos850
  arm64: dts: exynos: Add initial Exynos850 SoC support
  arm64: dts: exynos: Add initial E850-96 board support
