Hi folks,

This series adds initial support for the Exynos 990 SoC and also
initial board support for the Samsung Galaxy Note20 5G (SM-N981B)
codenamed c1s.

The Exynos 990 SoC is also used in the S20 series, as well as in the
Note 20 Ultra phones. Currently the device trees added are for the
Exynos 990 SoC and c1s. The device tree has been tested with 
dtbs_check W=1 and results in no warnings.

This initial bringup consists of:
 * cpus
 * pinctrl
 * gpio-keys
 * simple-framebuffer
 
This is enough to reach a shell in an initramfs. More platform support
will be added in the future.

The preferred way to boot the upstream kernel is by using a shim
bootloader, called uniLoader [1], which works around some issues with
the stock, non-replacable Samsung S-LK bootloader. For example, the
stock bootloader leaves the decon trigger control unset, which causes
the framebuffer not to refresh.

Device functionality depends on the 2nd patch series:
"Add Exynos990 pinctrl and chipid drivers"

[1] https://github.com/ivoszbg/uniLoader

Changes in v3:
 - Move pinctrl DT nodes from the 2nd patch series
 - Resend patches to the correct lists.

Changes in v2:
 - Added acked-by tag by Rob Herring
 - Fixed two stray newlines in SoC and device DTs
 - Fixed commit message for the c1s device tree
 - Changed osc-clock to clock-osc and ordered nodes in SoC DT
 - Fixed ordering in the gic node in SoC DT
 - Fixed memory node unit address
 - Fixed memory node reg properties, to map all available RAM
 - Moved pinctrl binding commits to the 2nd patch series.

Kind regards,
Igor

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

These are expected, coming via different tree.

Not sure if all thank-you letters are correct, but to be clear:
I applied entire patchset. Thank you!
