Subject: [PATCH v6 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.

Notes to Krzysztof:
  - This series is based on v5.17-rc2 tag; please let me know if you
    want me to rebase this series on top of some specific tree/branch
  - Please apply your patch for fixing gpio bank node names (including
    new 'gpm6' and 'gpm7' nodes added in this series) on top of this
    series

Changes in v6:
  - Got rid of clock magic numbers (added in v5), as corresponding clock
    patches are merged into mainline now
  - Integrated "arm64: dts: exynos: Add missing gpm6 and gpm7 nodes to
    Exynos850" patch into [1/2], so that separate patch can be dropped
    now

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
