Linux has in\naddition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were\nnever added in u-boot.\nThe most common use case for u-boot on Apple silicon devices does not\nuse DTBs from u-boot but passes runtime modified device trees from an\nearlier boot loader (m1n1).\nThis change regresses support for the DWC3 based USB-C ports and the SPI\nbased keyboard on M1 and M1 Pro/Max notebooks. The regression for the\nUSB-C ports will be fixed when dts/upstream is synced to Linux v7.0.\nThe dt-bindings and device tree nodes for the SPI keyboard has still to\nbe submitted upstream.\nThese regression are in my opinion acceptable due to the limited use of\nu-boot's DTBs for these targets.\n\nSigned-off-by: Janne Grunau \n---\nJanne Grunau (3):\n doc: board: apple: Mention M2 and M2 Pro/Max/Ultra SoCs\n doc: device-tree-bindings: Remove apple,pinctrl.yaml\n arm: dts: Switch Apple silicon devices to dts/upstream\n\n arch/arm/Kconfig | 1 +\n arch/arm/dts/Makefile | 7 -\n arch/arm/dts/t8103-j274-u-boot.dtsi | 1 -\n arch/arm/dts/t8103-j274.dts | 129 ---\n arch/arm/dts/t8103-j293-u-boot.dtsi | 1 -\n arch/arm/dts/t8103-j293.dts | 116 --\n arch/arm/dts/t8103-j313-u-boot.dtsi | 1 -\n arch/arm/dts/t8103-j313.dts | 111 --\n arch/arm/dts/t8103-j456-u-boot.dtsi | 1 -\n arch/arm/dts/t8103-j456.dts | 117 --\n arch/arm/dts/t8103-j457-u-boot.dtsi | 1 -\n arch/arm/dts/t8103-j457.dts | 105 --\n arch/arm/dts/t8103-jxxx.dtsi | 143 ---\n arch/arm/dts/t8103-pmgr.dtsi | 1138 --------------------\n arch/arm/dts/t8103-u-boot.dtsi | 25 -\n arch/arm/dts/t8103.dtsi | 696 ------------\n configs/apple_m1_defconfig | 2 +-\n doc/board/apple/m1.rst | 15 +-\n .../pinctrl/apple,pinctrl.yaml | 106 --\n 19 files changed, 11 insertions(+), 2705 deletions(-)\n---\nbase-commit: 88dc2788777babfd6322fa655df549a019aa1e69\nchange-id: 20260109-apple-dt-upstream-6daf03510fec\n\nBest regards,"}
