CIX SKY1 SoC is high performance Armv9 SoC designed by Cixtech, and Orion O6 is the motherboard launched by Radxa. See below for detail: https://docs.radxa.com/en/orion/o6/getting-started/introduction In this commit, it only adds limited components for running initramfs at Orion O6. Tested-by: Enric Balletbo i Serra <redacted> Tested-by: Kajetan Puchalski <redacted> Signed-off-by: Peter Chen <peter.chen@cixtech.com> Signed-off-by: Guomin Chen <redacted> Signed-off-by: Gary Yang <redacted> --- Changes for v10: - Address comments from Krzysztof about "shmem" node and delete two blank lines. Changes for v7: - Refine *_scmi_mem nodes for their properties ordering - Delete Krzysztof Kozlowski and Fugang Duan's tag due to substantial changes - Add two Tested-by tags from Enric Balletbo i Serra and Kajetan Puchalski Changes for v6: - Add mailbox, scmi and uart support Changes for v5: - Delete pmu-spe node which need to refine, and add it in future Changes for v4: - 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 - Add Krzysztof Kozlowski's reviewed-by Changes for v3: - Fix two dts coding sytle issues Changes for v2: - Corrects the SoF tag's name - Fix several coding sytle issues - move linux,cma node to dts file - delete memory node, memory size is passed by firmware - delete uart2 node which will be added in future patches - Improve for pmu and cpu node to stands for more specific cpu model - Improve the timer node and add hypervisor virtual timer irq - Pass "make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb" arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/cix/Makefile | 2 + arch/arm64/boot/dts/cix/sky1-orion-o6.dts | 39 +++ arch/arm64/boot/dts/cix/sky1.dtsi | 330 ++++++++++++++++++++++ 4 files changed, 372 insertions(+) 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
