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 [1] https://github.com/ivoszbg/uniLoader Igor Belwon (7): dt-bindings: arm: cpus: Add Samsung Mongoose M5 dt-bindings: hwinfo: exynos-chipid: Add compatible for Exynos 990 chipid dt-bindings: arm: samsung: samsung-boards: Add bindings for Exynos 990 boards. dt-bindings: pinctrl: samsung: Add exynos990-pinctrl compatible dt-bindings: pinctrl: samsung: add exynos990-wakeup-eint compatible arm64: dts: exynos: Add initial support for the Exynos 990 SoC arm64: boot: dts: Add initial support for Samsung Galaxy Note20 5G (c1s) .../devicetree/bindings/arm/cpus.yaml | 1 + .../bindings/arm/samsung/samsung-boards.yaml | 6 + .../hwinfo/samsung,exynos-chipid.yaml | 1 + .../samsung,pinctrl-wakeup-interrupt.yaml | 1 + .../bindings/pinctrl/samsung,pinctrl.yaml | 1 + arch/arm64/boot/dts/exynos/Makefile | 1 + arch/arm64/boot/dts/exynos/exynos990-c1s.dts | 111 + .../boot/dts/exynos/exynos990-pinctrl.dtsi | 2195 +++++++++++++++++ arch/arm64/boot/dts/exynos/exynos990.dtsi | 241 ++ 9 files changed, 2558 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos990-c1s.dts create mode 100644 arch/arm64/boot/dts/exynos/exynos990-pinctrl.dtsi create mode 100644 arch/arm64/boot/dts/exynos/exynos990.dtsi -- 2.45.2
