Pull ARM SoC DT updates from Kevin Hilman: "As usual, quite a few device-tree updates in ARM land. There was one minor churn in DTs due to relicensing under a dual-license, and lots of little additions of new peripherals, features etc, but nothing really exciting to call to your attention. Some higlights, focsuing on support for new SoCs and boards: - AT91: new boards: Overkiz, Acme Systems' Arietta G25 - tegra: HDA support - bcm: new platforms: Buffalo WXR-1900DHP, SmartRG SR400ac, ASUS RT-AC87U - mvebu: new platforms: Compulab CM-A510, Armada 385-based Linksys boards, DLink DNS-327L - OMAP: new platforms: Baltos IR5221, LogicPD Torpedo, Toby-Churchill SL50 - ARM: added support for Juno r1 board - sunxi: A33 SoC support; new boards: A23 EVB, SinA33, GA10H-A33, Mele A1000G - imx: i.MX7D SoC support; new boards: Armadeus Systems APF6, Gateworks GW5510, and aristainetos2 boards - hisilicon: hi6220 SoC support; new boards: 96boards hikey" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (462 commits) ARM: hisi: revert changes from hisi/hip04-dt branch ARM: nomadik: set proper compatible for accelerometer ARM64: juno: add GPIO keys ARM: at91/dt: sama5d4: fix dma conf for aes, sha and tdes nodes ARM: dts: Introduce STM32F429 MCU ARM: socfpga: dts: enable ethernet for Arria10 devkit ARM: dts: k2l: fix the netcp range size ARM: dts: k2e: fix the netcp range size ARM: dts: k2hk: fix the netcp range size ARM: dts: k2l-evm: Add device bindings for netcp driver ARM: dts: k2e-evm: Add device bindings for netcp driver ARM: dts: k2hk-evm: Add device bindings for netcp driver ARM: BCM5301X: Add DT for Asus RT-AC87U ARM: BCM5301X: add IRQ numbers for PCIe controller ARM: BCM5301X: add NAND flash chip description arm64: dts: Add dts files for Hisilicon Hi6220 SoC clk: hi6220: Document devicetree bindings for hi6220 clock arm64: hi6220: Document devicetree bindings for Hisilicon hi6220 SoC ARM: at91/dt: sama5d4ek: mci0 uses slot 0 ARM: at91/dt: kizbox: fix mismatch LED PWM device ...

Required root node property:
compatible: should be "brcm,bcm63138"
+
+An optional Boot lookup table Device Tree node is required for secondary CPU
+initialization as well as a 'resets' phandle to the correct PMB controller as
+defined in reset/brcm,bcm63138-pmb.txt for this secondary CPU, and an
+'enable-method' property.
+
+Required properties for the Boot lookup table node:
+- compatible: should be "brcm,bcm63138-bootlut"
+- reg: register base address and length for the Boot Lookup table
+
+Optional properties for the primary CPU node:
+- enable-method: should be "brcm,bcm63138"
+
+Optional properties for the secondary CPU node:
+- enable-method: should be "brcm,bcm63138"
+- resets: phandle to the relevant PMB controller, one integer indicating the internal
+ bus number, and a second integer indicating the address of the CPU in the PMB
+ internal bus number.
+
+Example:
+
+ cpus {
+ cpu@0 {
+ compatible = "arm,cotex-a9";
+ reg = <0>;
+ ...
+ enable-method = "brcm,bcm63138";
+ };
+
+ cpu@1 {
+ compatible = "arm,cortex-a9";
+ reg = <1>;
+ ...
+ enable-method = "brcm,bcm63138";
+ resets = <&pmb0 4 1>;
+ };
+ };
+
+ bootlut: bootlut@8000 {
+ compatible = "brcm,bcm63138-bootlut";
+ reg = <0x8000 0x50>;
+ };
+
+=======
+reboot
+------
+Two nodes are required for software reboot: a timer node and a syscon-reboot node.
+
+Timer node:
+
+- compatible: Must be "brcm,bcm6328-timer", "syscon"
+- reg: Register base address and length
+
+Syscon reboot node:
+
+See Documentation/devicetree/bindings/power/reset/syscon-reboot.txt for the
+detailed list of properties, the two values defined below are specific to the
+BCM6328-style timer:
+
+- offset: Should be 0x34 to denote the offset of the TIMER_WD_TIMER_RESET register
+ from the beginning of the TIMER block
+- mask: Should be 1 for the SoftRst bit.
+
+Example:
+
+ timer: timer@80 {
+ compatible = "brcm,bcm6328-timer", "syscon";
+ reg = <0x80 0x3c>;
+ };
+
+ reboot {
+ compatible = "syscon-reboot";
+ regmap = <&timer>;
+ offset = <0x34>;
+ mask = <0x1>;
+ };
