Pull ARM devicetree updates from Olof Johansson: "Like always, the DT branch is sizable. There are numerous additions and fixes to existing platforms, but also a handful of new ones introduced. Less than some other releases, but there's been significant work on cleanups, refactorings and device enabling on existing platforms. A non-exhaustive list of new material: - Refactoring of BCM2711 dtsi structure to add support for the Raspberry Pi 400 - Rockchip: RK3568 SoC and EVB, video codecs for rk3036/3066/3188/322x - Qualcomm: SA8155p Automotive platform (SM8150 derivative), SM8150/8250 enhancements and support for Sony Xperia 1/1II and 5/5II - TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc definitions - TI OMAP: Various cleanups - Tegra: Audio support for Jetson Xavier NX, SMMU support on Tegra194 - Qualcomm: lots of additions for peripherals across several SoCs, and new support for Microsoft Surface Duo (SM8150-based), Huawei Ascend G7. - i.MX: Numerous additions of features across SoCs and boards. - Allwinner: More device bindings for V3s, Forlinx OKA40i-C and NanoPi R1S H5 boards - MediaTek: More device bindings for mt8167, new Chromebook system variants for mt8183 - Renesas: RZ/G2L SoC and EVK added - Amlogic: BananaPi BPI-M5 board added" * tag 'arm-dt-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (511 commits) arm64: dts: rockchip: add basic dts for RK3568 EVB arm64: dts: rockchip: add core dtsi for RK3568 SoC arm64: dts: rockchip: add generic pinconfig settings used by most Rockchip socs ARM: dts: rockchip: add vpu and vdec node for RK322x ARM: dts: rockchip: add vpu nodes for RK3066 and RK3188 ARM: dts: rockchip: add vpu node for RK3036 arm64: dts: ipq8074: Add QUP6 I2C node arm64: dts: rockchip: Re-add regulator-always-on for vcc_sdio for rk3399-roc-pc arm64: dts: rockchip: Re-add regulator-boot-on, regulator-always-on for vdd_gpu on rk3399-roc-pc arm64: dts: rockchip: add ir-receiver for rk3399-roc-pc arm64: dts: rockchip: Add USB-C port details for rk3399 Firefly arm64: dts: rockchip: Sort rk3399 firefly pinmux entries arm64: dts: rockchip: add infrared receiver node to RK3399 Firefly arm64: dts: rockchip: add SPDIF node for rk3399-firefly arm64: dts: rockchip: Add Rotation Property for OGA Panel arm64: dts: qcom: sc7180: bus votes for eMMC and SD card arm64: dts: qcom: sm8250-edo: Add Samsung touchscreen arm64: dts: qcom: sm8250-edo: Enable GPI DMA arm64: dts: qcom: sm8250-edo: Enable ADSP/CDSP/SLPI arm64: dts: qcom: sm8250-edo: Enable PCIe ...
