Add initial support for the Samsung Galaxy Note20 5G (c1s/SM-N981B) phone. It was launched in 2020, and it's based on the Exynos 990 SoC. It has only one configuration with 8GB of RAM, albeit storage options may differ. This device tree adds support for the following: - SimpleFB - 8GB RAM - Buttons Signed-off-by: Igor Belwon <igor.belwon@mentallysanemainliners.org> --- arch/arm64/boot/dts/exynos/Makefile | 1 + arch/arm64/boot/dts/exynos/exynos990-c1s.dts | 111 +++++++++++++++++++ 2 files changed, 112 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos990-c1s.dts
