Merge tag 'late-dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC late changes from Kevin Hilman:
 "These are changes that arrived a little late but were considered
  self-contained enough to still go in for v3.14.

  They are all device tree updtes this time around, and mainly for
  Broadcom SoCs"

Broadcom Kona Family Clocks



This binding is associated with Broadcom SoCs having "Kona" style

clock control units (CCUs).  A CCU is a clock provider that manages

a set of clock signals.  Each CCU is represented by a node in the

device tree.



This binding uses the common clock binding:

    Documentation/devicetree/bindings/clock/clock-bindings.txt



Required properties:

- compatible

	Shall have one of the following values:

	- "brcm,bcm11351-root-ccu"

	- "brcm,bcm11351-aon-ccu"

	- "brcm,bcm11351-hub-ccu"

	- "brcm,bcm11351-master-ccu"

	- "brcm,bcm11351-slave-ccu"

- reg

	Shall define the base and range of the address space

	containing clock control registers

- #clock-cells

	Shall have value <1>.  The permitted clock-specifier values

	are defined below.

- clock-output-names

	Shall be an ordered list of strings defining the names of

	the clocks provided by the CCU.





BCM281XX family SoCs use Kona CCUs.  The following table defines

the set of CCUs and clock specifiers for BCM281XX clocks.  When

a clock consumer references a clocks, its symbolic specifier

(rather than its numeric index value) should be used.  These

specifiers are defined in "include/dt-bindings/clock/bcm281xx.h".
