Merge tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM 64-bit DT updates from Arnd Bergmann: "The arm64 device tree changes make up an increasing portion of the overall changes, so they are kept separate from the 32-bit devicetree changes and from the other arm64 updates. Newly added SoCs and boards are: - 96Boards Husky board - AMD Overdrive board - Amlogic S905 SoC and related Tronsmart boxes - Annapurna Labs Alpine family and development board - Broadcom Vulcan servers - Broadcom Northstar 2 SoC - Marvell Armada 3700 family and development board - Qualcomm MSM8996 SoC Additional devices are enabled for existing platforms from Applied Micro, Hisilicon, Mediatek, Qualcomm, and Renesas and there are a couple of other updates for Rockchip, Xilinx and NXP/Freescale" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (102 commits) ARM64: dts: amlogic: Add Tronsmart Vega S95 configs Documentation: devicetree: amlogic: Document Tronsmart Vega S95 boards ARM64: dts: Prepare configs for Amlogic Meson GXBaby Documentation: devicetree: amlogic: Document Meson GXBaby devicetree: bindings: Add vendor prefix for Tronsmart arm64: dts: qcom: Fix MPP's function used for LED control arm64: dts: alpine: add the MSIX node in the Alpine v2 dtsi arm64: dts: add the Alpine v2 EVP arm64: dts: marvell: re-order Device Tree nodes for Armada AP806 arm64: dts: marvell: update Armada AP806 clock description arm64: dts: marvell: add Device Tree files for Armada 7K/8K arm64: dts: apm: Add DT node for X-Gene v2 SLIMpro Mailbox I2C Driver arm64: dts: apm: Mailbox device tree node for APM X-Gene v2 platform. arm64: dts: apm: Add DT node for X-Gene v1 SLIMpro Mailbox I2C Driver arm64: dts: apm: mailbox device tree node for APM X-Gene platform. arm64: dts: apm: Update GPIO to control power-off on X-Gene v2 platforms arm64: dts: apm: Update GPIO standby controller DT node for X-Gene v2 platforms arm64: dts: apm: Update GPIO to control power-off on X-Gene v1 platforms arm64: dts: salvator-x: enable USB 2.0 Host of channel 1 and 2 arm64: dts: salvator-x: enable usb2_phy of channel 1 and 2 ...

+ARM AMBA Primecell SP805 Watchdog
+
+Required properties:
+- compatible: Should be "arm,sp805" & "arm,primecell"
+- reg: Should contain location and length for watchdog timer register.
+- interrupts: Should contain the list of watchdog timer interrupts.
+- clocks: clocks driving the watchdog timer hardware. This list should be 2
+ clocks. With 2 clocks, the order is wdogclk clock, apb_pclk.
+
+Example:
+ watchdog@66090000 {
+ compatible = "arm,sp805", "arm,primecell";
+ reg = <0x66090000 0x1000>;
+ interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&apb_pclk>,<&apb_pclk>;
+ clock-names = "wdogclk", "apb_pclk";
+ };
