1Broadcom BCM53573 ILP clock
2===========================
3
4This binding uses the common clock binding:
5    Documentation/devicetree/bindings/clock/clock-bindings.txt
6
7This binding is used for ILP clock (sometimes referred as "slow clock")
8on Broadcom BCM53573 devices using Cortex-A7 CPU.
9
10ILP's rate has to be calculated on runtime and it depends on ALP clock
11which has to be referenced.
12
13This clock is part of PMU (Power Management Unit), a Broadcom's device
14handing power-related aspects. Its node must be sub-node of the PMU
15device.
16
17Required properties:
18- compatible: "brcm,bcm53573-ilp"
19- clocks: has to reference an ALP clock
20- #clock-cells: should be <0>
21- clock-output-names: from common clock bindings, should contain clock
22		      name
23
24Example:
25
26pmu@18012000 {
27	compatible = "simple-mfd", "syscon";
28	reg = <0x18012000 0x00001000>;
29
30	ilp {
31		compatible = "brcm,bcm53573-ilp";
32		clocks = <&alp>;
33		#clock-cells = <0>;
34		clock-output-names = "ilp";
35	};
36};
