    1 Broadcom BCM53573 ILP clock
    2 ===========================
    3 
    4 This binding uses the common clock binding:
    5     Documentation/devicetree/bindings/clock/clock-bindings.txt
    6 
    7 This binding is used for ILP clock (sometimes referred as "slow clock")
    8 on Broadcom BCM53573 devices using Cortex-A7 CPU.
    9 
   10 ILP's rate has to be calculated on runtime and it depends on ALP clock
   11 which has to be referenced.
   12 
   13 This clock is part of PMU (Power Management Unit), a Broadcom's device
   14 handing power-related aspects. Its node must be sub-node of the PMU
   15 device.
   16 
   17 Required 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 
   24 Example:
   25 
   26 pmu@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 };
