Pull ARM device-tree updates from Arnd Bergmann: "Device-tree continues to see lots of updates. The majority of patches here are smaller changes for new hardware on existing platforms, and there are a few larger changes worth pointing out. New machines: - The new Action Semi S500 platform is added along with initial support for the LeMaker Guitar board. - STM32 gains support for three new boards: stm32h743-disco, stm32f746-disco, and stm32f769-disco, along with new device support for the existing stm32f429 boards. - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H with 10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module plus board. - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM wireless router. - For NXP i.MX, we gain support for the Gateworks Ventana GW5600 and the Technexion Pico i.MX7D single-board computers. - The BeagleBone Blue is added for OMAP, it's the latest variation of the popular Beaglebone Black single-board computer. - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards are added, these are the latest variations of a seemingly endless supply of similar single-board computers. Other updates: - Linus Walleij improves support for the "Faraday" based SoC platforms from various SoC makers (Moxart, Aspeed, Gemini) - The ARM Mali GPU is now describe on Rockchips SoCs - Mediatek MT7623 is extended significantly, making it much more useful. - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom, Allwinner, Qualcomm, iMX - For Amlogic, the clock support is extended a lot on meson8b. - We now build the devicetree file for the Raspberry Pi 3 on 32-bit ARM, in addition to the existing ARM64 support, to help users wanting to run a 32-bit system on it" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (345 commits) ARM: dts: socfpga: set the i2c frequency ARM: dts: socfpga: Add second ethernet alias to VINING FPGA ARM: dts: socfpga: Drop LED node from VINING FPGA ARM: dts: socfpga: Remove I2C EEPROMs from VINING FPGA ARM: dts: socfpga: Enable QSPI support on VINING FPGA ARM: dts: socfpga: Fix the ethernet clock phandle ARM: pxa: Use - instead of @ for DT OPP entries ARM: dts: owl-s500: Add SPS node ARM: dts: owl-s500: Set CPU enable-method dt-bindings: arm: cpus: Add S500 enable-method ARM: dts: Add Actions Semi S500 and LeMaker Guitar dt-bindings: arm: Document Actions Semi S900 dt-bindings: timer: Document Owl timer ARM: dts: imx6q-cm-fx6: add sdio wifi/bt nodes dt-bindings: arm: Document Actions Semi S500 dt-bindings: Add vendor prefix for Actions Semi ARM: dts: turris-omnia: Add generic compatible string for I2C EEPROM ARM: dts: mvebu: add support for Linksys WRT3200ACM (Rango) ARM: dts: armada-385-linksys: fixup button node names ARM: dts: armada-385-linksys: group pins in pinctrl ...

+ARM Mali Midgard GPU
+====================
+
+Required properties:
+
+- compatible :
+ * Must contain one of the following:
+ + "arm,mali-t604"
+ + "arm,mali-t624"
+ + "arm,mali-t628"
+ + "arm,mali-t720"
+ + "arm,mali-t760"
+ + "arm,mali-t820"
+ + "arm,mali-t830"
+ + "arm,mali-t860"
+ + "arm,mali-t880"
+ * which must be preceded by one of the following vendor specifics:
+ + "amlogic,meson-gxm-mali"
+ + "rockchip,rk3288-mali"
+
+- reg : Physical base address of the device and length of the register area.
+
+- interrupts : Contains the three IRQ lines required by Mali Midgard devices.
+
+- interrupt-names : Contains the names of IRQ resources in the order they were
+ provided in the interrupts property. Must contain: "job", "mmu", "gpu".
+
+
+Optional properties:
+
+- clocks : Phandle to clock for the Mali Midgard device.
+
+- mali-supply : Phandle to regulator for the Mali device. Refer to
+ Documentation/devicetree/bindings/regulator/regulator.txt for details.
+
+- operating-points-v2 : Refer to Documentation/devicetree/bindings/power/opp.txt
+ for details.
