Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates from Arnd Bergmann: "We get a moderate number of new machines this time, and only one new SoC variant (Actions S700): Actions: - S700 Soc and CubieBoard7 development board - Allo.com Sparky Single-board-computer Allwinner: - Orange Pi R1 development board - Libre Computer Board ALL-H3-CC H3 single-board computer ASpeed ast2x00: - Witherspoon: OpenPower Power9 server manufactured by IBM that uses the ASPEED ast2500 - Zaius: OpenPower Power9 server manufactured by Invatech that uses the ASPEED ast2500 - Q71L: Intel Xeon server manufactured by Qanta that uses the ASPEED ast2400 AT91: - Axentia Nattis/Natte digital signage - sama5d2 PTC-ek Evaluation board Freescale/NXP i.MX: - SolidRun Humminboard2 development board - Variscite DART-MX6 SoM and Carrier-board - Technologic TS-4600 and TS-7970 development board - Toradex Colibri iMX7D SoM board - v1.5 variant of Solidrun Cubox-i and Hummingboard Freescale/NXP Layerscape: - Moxa UC-8410A Series industrial computer Gemini: - D-Link DNS-313 NAS enclosure OMAP: - LogicPD OMAP35xx SOM-LV devkit - LogicPD OMAP35xx Torpedo devkit Renesas: - r8a77970 (V3M) Starter Kit board - r8a7795 (M3-W) Salvator-XS board We finally managed to get the dtc warnings under control, with no more build-time warnings for bad device tree files. This includes fixes for the majority of platforms, including nomadik, samsung, lpc32xx, STi, spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood, renesas, hisilicon, and broadcom. Files get rearranged on a few platforms, in particular the Marvell Armada 7K/8K device tree files are changed in preparation for future SoC support, based on more than two of the same chips in one package, and some boards get renamed for oxnas for consistency. Finally, many existing SoCs gain descriptions for additional on-chip devices that we can now support with kernel drivers: - Allwinner A83t (drm, ethernet, i2c, ...), H3/H5 (USB-OTG) - Amlogic AXG family (clk, pinctrl, pwm, ...), and others (vpu, hdmi) - Aspeed clk controller support - Freescale LS1088A, LS1021A device support - Gemini Ethernet, PCI, TVE, panel - Keystone gpio, qspi, more uarts - Mediatek cpufreq, regulator, clock, reset - Marvell thermal, cpufreq, nand - Renesas SMP, thermal, timer, PWM, sound, phy, ipmmu - Rockchip Mipi, GPU, display - Samsung Exynos5433 PMU, power domain, nfc - Spreadtrum: sc9860 clocks - Tegra TX2 PSDI, HDMI, I2C,SMMU, display, fuse, ..." * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (690 commits) arm64: dts: stratix10: fix SPI settings ARM: dts: socfpga: add i2c reset signals arm64: dts: stratix10: add USB ECC reset bit arm64: dts: stratix10: enable USB on the devkit ARM: dts: socfpga: disable over-current for Arria10 USB devkit ARM: dts: Nokia N9: add support for up/down keys in the dts ARM: dts: nomadik: add interrupt-parent for clcd ARM: dts: Add ethernet to a bunch of platforms ARM: dts: Add ethernet to the Gemini SoC ARM: dts: rename oxnas dts files ARM: dts: s5pv210: add interrupt-parent for ohci ARM: lpc3250: fix uda1380 gpio numbers ARM: dts: STi: Add gpio polarity for "hdmi,hpd-gpio" property ARM: dts: dra7: Reduce shut down temperature of non-cpu thermal zones ARM: dts: n900: Add aliases for lcd and tvout displays ARM: dts: Update ti-sysc data for existing users ARM: dts: Fix smartreflex compatible for omap3 shared mpu-iva instance arm64: dts: marvell: armada-80x0: Fix pinctrl compatible string arm: spear13xx: Fix spics gpio controller's warning arm: spear13xx: Fix dmas cells ...
