Merge tag 'arm-soc/for-4.2/dts' of http://github.com/broadcom/stblinux into next/dt 

Merge "Device Tree changes" from Florian Fainelli:

New devices:

- Felix adds support for the Buffalo WXR-1900DHP and adds the USB led on Buffalo
  WZR-1750DHP

- Rafal adds support for the SmartRG SR400ac, Asus RT-AC68U and RT-AC56U

New peripheral support:

- Brian adds Device Tree nodes for the Broadcom NAND controller found on
  BCM7xxx, BCM63138 and Cygnus SoCs

- Brian adds Device Tree nodes for the SATA AHCI and PHY controller found on
  BCM7xxx

- I add the Device Tree nodes and bindings documents for bringing-up secondary
  CPUs and timer/syscon-reboot on BCM63138

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>;

		};

	};

		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>;

	};

Broadcom BCM63138 Processor Monitor Bus binding

===============================================



Please also refer to reset.txt in this directory for common reset

controller binding usage.



Require properties:



- compatible: must be "brcm,bcm63138-pmb"

- reg: base register address and size for this bus controller

- #reset-cells: must be 2 first cell is the address within the bus instance designated

  by the phandle, and the second is the number of zones for this peripheral



Example:

	pmb0: reset-controller@4800c0 {

		compatible = "brcm,bcm63138-pmb";

		reg = <0x4800c0 0x10>;

		#reset-cells = <2>;
