Pull ARM Devicetree updates from Olof Johansson: "We continue to see a lot of new material. I've highlighted some of it below, but there's been more beyond that as well. One of the sweeping changes is that many boards have seen their ARM Mali GPU devices added to device trees, since the DRM drivers have now been merged. So, with the caveat that I have surely missed several great contributions, here's a collection of the material this time around: New SoCs: - Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53) - TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA) - Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53) New Boards / platforms: - Aspeed BMC support for a number of new server platforms - Kontron SMARC SoM (several i.MX6 versions) - Novtech's Meerkat96 (i.MX7) - ST Micro Avenger96 board - Hardkernel ODROID-N2 (Amlogic G12B) - Purism Librem5 devkit (i.MX8MQ) - Google Cheza (Qualcomm SDM845) - Qualcomm Dragonboard 845c (Qualcomm SDM845) - Hugsun X99 TV Box (Rockchip RK3399) - Khadas Edge/Edge-V/Captain (Rockchip RK3399) Updated / expanded boards and platforms: - Renesas r7s9210 has a lot of new peripherals added - Fixes and polish for Rockchip-based Chromebooks - Amlogic G12A has a lot of peripherals added - Nvidia Jetson Nano sees various fixes and improvements, and is now at feature parity with TX1" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (586 commits) ARM: dts: gemini: Set DIR-685 SPI CS as active low ARM: dts: exynos: Adjust buck[78] regulators to supported values on Arndale Octa ARM: dts: exynos: Adjust buck[78] regulators to supported values on Odroid XU3 family ARM: dts: exynos: Move Mali400 GPU node to "/soc" ARM: dts: exynos: Fix imprecise abort on Mali GPU probe on Exynos4210 arm64: dts: qcom: qcs404: Add missing space for cooling-cells property arm64: dts: rockchip: Fix USB3 Type-C on rk3399-sapphire arm64: dts: rockchip: Update DWC3 modules on RK3399 SoCs arm64: dts: rockchip: enable rk3328 watchdog clock ARM: dts: rockchip: add display nodes for rk322x ARM: dts: rockchip: fix vop iommu-cells on rk322x arm64: dts: rockchip: Add support for Hugsun X99 TV Box arm64: dts: rockchip: Define values for the IPA governor for rock960 arm64: dts: rockchip: Fix multiple thermal zones conflict in rk3399.dtsi arm64: dts: rockchip: add core dtsi file for RK3399Pro SoCs arm64: dts: rockchip: improve rk3328-roc-cc rgmii performance.
