Merge tag 'soc-dt-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC DT updates from Arnd Bergmann: "About a quarter of the changes are for 32-bit arm, mostly filling in device support for existing machines and adding minor cleanups, mostly for Qualcomm and Samsung based machines. Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from Rockchips that have been around for a while but were lacking kernel support so far: RV1126 is a Vision SoC with an NPU and is used in the Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for TV boxes and so far only comes with a dts for its refernece design. The other 32-bit boards that were added are two ASpeed AST2600 based BMC boards, the Microchip sam9x60_curiosity development board (Armv5 based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53 and i.MX6ULL. On the RISC-V side, there are fewer patches, but a total of ten new single-board computers based on variations of the Allwinner D1/T113 chip, plus one more board based on Microchip Polarfire. As usual, arm64 has by far the most changes here, with over 700 non-merge changesets, among them over 400 alone for Qualcomm. The newly added SoCs this time are all recent high-end embedded SoCs for various markets, each on comes with support for its reference board: - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones - Qualcomm QDU1000/QRU1000 5G RAN platform - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs - TI J784S4 for industrial and automotive applications In total, there are 46 new arm64 machines: - Reference platforms for each of the five new SoCs - Three Amlogic based development boards - Six embedded machines based on NXP i.MX8MM and i.MX8MP - The Mediatek mt7986a based Banana Pi R3 router - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115 (Snapdragon 662) and SM8250 (Snapdragon 865) - Two LTE dongles, also based on MSM8916 - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610), SDM450 and SDM632 - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c) - Nine development boards based on Rockchips RK3588, RK3568, RK3566 and RK3328. - Five development machines based on TI K3 (AM642/AM654/AM68/AM69) The cleanup of dtc warnings continues across all platforms, adding to the total number of changes" * tag 'soc-dt-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (1035 commits) dt-bindings: riscv: correct starfive visionfive 2 compatibles ARM: dts: socfpga: Add enclustra PE1 devicetree dt-bindings: altera: Add enclustra mercury PE1 arm64: dts: qcom: msm8996: align RPM G-Link clock-controller node with bindings arm64: dts: qcom: qcs404: align RPM G-Link node with bindings arm64: dts: qcom: ipq6018: align RPM G-Link node with bindings arm64: dts: qcom: sm8550: remove invalid interconnect property from cryptobam arm64: dts: qcom: sc7280: Adjust zombie PWM frequency arm64: dts: qcom: sc8280xp-pmics: Specify interrupt parent explicitly arm64: dts: qcom: sm7225-fairphone-fp4: enable remaining i2c busses arm64: dts: qcom: sm7225-fairphone-fp4: move status property down arm64: dts: qcom: pmk8350: Use the correct PON compatible arm64: dts: qcom: sc8280xp-x13s: Enable external display arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink arm64: dts: qcom: sc8280xp: Add USB-C-related DP blocks arm64: dts: qcom: sm8350-hdk: enable GPU arm64: dts: qcom: sm8350: add GPU, GMU, GPU CC and SMMU nodes arm64: dts: qcom: sm8350: finish reordering nodes arm64: dts: qcom: sm8350: move more nodes to correct place arm64: dts: qcom: sm8350: reorder device nodes ...
