Cixtech P1 (internal name sky1) is high performance generic Armv9 SoC. Orion O6 is the world's first open source Arm V9 Motherboard built by Radxa. You could find brief introduction for SoC and related boards at: https://radxa.com/products/orion/o6#overview In this series, we add initial SoC and board support for Kernel building. Patch 1-2: Add dt-binding doc for CIX and its sky1 SoC Patch 3: add related maintainers entry Patch 4-5: add Arm64 build support Patch 6: add initial dts support for SoC and Orion O6 board To run upstream kernel at Orion O6 board, you need to use BIOS released by Radxa: https://docs.radxa.com/en/orion/o6/bios/install-bios Changes for v4: - Move add MAINTAINERS entry patch to the last, and add two dts files entry in it. - Add three Krzysztof Kozlowski's Reviewed-by Tags - For sky1.dtsi, makes below changes: - Add ppi-partition entry for gic-v3 node, and let pmu-a520 and pmu-a720's interrupt entry get its handle - Remove gic-v3's #redistributor-regions and redistributor-stride properties - Change gic-v3's #interrupt-cells as 4, and change all interrupt specifiers accordingly - Remove "arm,no-tick-in-suspend" for timer due to global counter is at always-on power domain - Remove timer's clock frequency due to firmware has already set it Changes for v3: - Patch 1: Add Krzysztof Kozlowski's Acked-by Tag - Patch 2: Add Krzysztof Kozlowski's Reviewed-by Tag - Patch 6: Fix two dts coding sytle issues Changes for v2: - Pass dts build check with below commands: make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=vendor-prefixes.yaml make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=arm/cix.yaml make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb - Re-order the patch set, and move vendor-perfixes to the 1st patch. - Patch 4: Ordered Kconfig config entry by alpha-numerically - Patch 5: Corrects the Ack tag's name - Patch 6: see below. 1) Corrects the SoF tag's name 2) Fix several coding sytle issues 3) move linux,cma node to dts file 4) delete memory node, memory size is passed by firmware 5) delete uart2 node which will be added in future patches 6) Improve for pmu and cpu node to stands for more specific cpu model 7) Improve the timer node and add hypervisor virtual timer irq Fugang Duan (1): arm64: Kconfig: add ARCH_CIX for cix silicons Peter Chen (5): dt-bindings: vendor-prefixes: Add CIX Technology Group Co., Ltd. dt-bindings: arm: add CIX P1 (SKY1) SoC arm64: defconfig: Enable CIX SoC arm64: dts: cix: add initial CIX P1(SKY1) dts support MAINTAINERS: Add CIX SoC maintainer entry .../devicetree/bindings/arm/cix.yaml | 26 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 10 + arch/arm64/Kconfig.platforms | 6 + arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/cix/Makefile | 2 + arch/arm64/boot/dts/cix/sky1-orion-o6.dts | 26 ++ arch/arm64/boot/dts/cix/sky1.dtsi | 222 ++++++++++++++++++ arch/arm64/configs/defconfig | 1 + 9 files changed, 296 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/cix.yaml create mode 100644 arch/arm64/boot/dts/cix/Makefile create mode 100644 arch/arm64/boot/dts/cix/sky1-orion-o6.dts create mode 100644 arch/arm64/boot/dts/cix/sky1.dtsi -- 2.25.1
