This series contains dt-bindings updates and device trees for Apple silicon devices based on the M2 SoC (t8112). Device tree validation depends on the dart-t8110 bindings queued in the iommu tree for 6.3 [1], PMU updates [2] and support for "local-mac-address" for brcm,bcm4329-fmac based devices [3]. The latter fixes validation errors for the existing M1 and M1 Pro/Max/Ultra device trees. The device trees are tested with the downstream Asahi Linux kernel and on top of v6.2-rc5. The hardware is of limited use with the upstream kernel. The notebooks miss keyboard/trackpad drivers and usb support. The Mac mini does not yet have a boot framebuffer and lacks usb support as well. 1: https://lore.kernel.org/linux-iommu/20230113105029.26654-1-marcan@xxxxxxxxx/ 2: https://lore.kernel.org/linux-devicetree/20230214-apple_m2_pmu-v1-1-9c9213ab9b63@xxxxxxxxxx/ 3: https://lore.kernel.org/linux-devicetree/20230203-dt-bindings-network-class-v2-2-499686795073@xxxxxxxxxx/ The dt-binding changes in this series are documentation only. All drivers are compatible with the HW on the M2 SoC and are probed based on generic compatibles. The t8112 specific compatibles are added to address t8112 specific quirks in the case they become required. Signed-off-by: Janne Grunau <j@xxxxxxxxxx> --- Changes in v2: - collect acked/reviewed-by: tags - disable unused PCIe ports instead of deleting them - fixes based on review feedback for "apple,aic2" and "apple,sart" - dropped "arm-pmu: Add PMU compatible strings for Apple M2 cores" (submitted separately) - Link to v1: https://lore.kernel.org/r/20230202-asahi-t8112-dt-v1-0-cb5442d1c229@xxxxxxxxxx --- Hector Martin (2): dt-bindings: power: apple,pmgr-pwrstate: Add t8112 compatible arm64: dts: apple: t8112: Initial t8112 (M2) device trees Janne Grunau (14): dt-bindings: arm: apple: apple,pmgr: Add t8112-pmgr compatible dt-bindings: watchdog: apple,wdt: Add t8112-wdt compatible dt-bindings: arm: cpus: Add apple,avalanche & blizzard compatibles dt-bindings: interrupt-controller: apple,aic2: Add apple,t8112-aic compatible dt-bindings: iommu: apple,sart: Add apple,t8112-sart compatible string dt-bindings: mailbox: apple,mailbox: Add t8112 compatibles dt-bindings: nvme: apple: Add apple,t8112-nvme-ans2 compatible string dt-bindings: pci: apple,pcie: Add t8112 support dt-bindings: pinctrl: apple,pinctrl: Add apple,t8112-pinctrl compatible dt-bindings: i2c: apple,i2c: Add apple,t8112-i2c compatible dt-bindings: clock: apple,nco: Add t8112-nco compatible dt-bindings: sound: apple,mca: Add t8112-mca compatible dt-bindings: dma: apple,admac: Add t8112-admac compatible dt-bindings: arm: apple: Add t8112 j413/j473/j493 compatibles Documentation/devicetree/bindings/arm/apple.yaml | 15 + .../devicetree/bindings/arm/apple/apple,pmgr.yaml | 1 + Documentation/devicetree/bindings/arm/cpus.yaml | 2 + .../devicetree/bindings/clock/apple,nco.yaml | 1 + .../devicetree/bindings/dma/apple,admac.yaml | 1 + .../devicetree/bindings/i2c/apple,i2c.yaml | 1 + .../bindings/interrupt-controller/apple,aic2.yaml | 23 +- .../devicetree/bindings/iommu/apple,sart.yaml | 10 +- .../devicetree/bindings/mailbox/apple,mailbox.yaml | 2 + .../devicetree/bindings/nvme/apple,nvme-ans.yaml | 5 +- .../devicetree/bindings/pci/apple,pcie.yaml | 1 + .../devicetree/bindings/pinctrl/apple,pinctrl.yaml | 1 + .../bindings/power/apple,pmgr-pwrstate.yaml | 1 + .../devicetree/bindings/sound/apple,mca.yaml | 1 + .../devicetree/bindings/watchdog/apple,wdt.yaml | 1 + arch/arm64/boot/dts/apple/Makefile | 3 + arch/arm64/boot/dts/apple/t8112-j413.dts | 63 ++ arch/arm64/boot/dts/apple/t8112-j473.dts | 54 + arch/arm64/boot/dts/apple/t8112-j493.dts | 52 + arch/arm64/boot/dts/apple/t8112-jxxx.dtsi | 81 ++ arch/arm64/boot/dts/apple/t8112-pmgr.dtsi | 1141 ++++++++++++++++++++ arch/arm64/boot/dts/apple/t8112.dtsi | 912 ++++++++++++++++ 22 files changed, 2365 insertions(+), 7 deletions(-) --- base-commit: 1b929c02afd37871d5afb9d498426f83432e71c2 change-id: 20230202-asahi-t8112-dt-6fc880c8cd73 Best regards, -- Janne Grunau <j@xxxxxxxxxx>
