Subject: [PATCH v1 0/7] Add minimal Exynos990 SoC and SM-N981B support

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"

Kind regards,
Igor
