…ernel/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" * tag 'late-dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: moxart: move fixed rate clock child node to board level dts clk: bcm281xx: define kona clock binding ARM: dts: add usb udc support to bcm281xx ARM: dts: Specify clocks for timer on bcm11351 Documentation: dt: kona-timer: Add clocks property ARM: dts: Specify clocks for SDHCIs on bcm11351 Documentation: dt: kona-sdhci: Add clocks property ARM: dts: Specify clocks for UARTs on bcm11351 ARM: dts: bcm281xx: Add i2c busses ARM: dts: Declare clocks as fixed on bcm11351 ARM: dts: bcm28155-ap: Enable all the i2c busses

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". | ||
