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".
