This clock is present on BCM53573 devices (including BCM47189) that use Cortex-A7. ILP is a part of PMU (Power Management Unit) multi-function device so we use syscon (and regmap) for it.

Broadcom BCM53573 ILP clock
|
|
===========================
|
|
|
|
This binding uses the common clock binding:
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
|
|
|
This binding is used for ILP clock (sometimes referred as "slow clock")
|
|
on Broadcom BCM53573 devices using Cortex-A7 CPU.
|
|
|
|
ILP's rate has to be calculated on runtime and it depends on ALP clock
|
|
which has to be referenced.
|
|
|
|
This clock is part of PMU (Power Management Unit), a Broadcom's device
|
|
handing power-related aspects. Its node must be sub-node of the PMU
|
|
device.
|
|
|
|
Required properties:
|
|
- compatible: "brcm,bcm53573-ilp"
|
|
- clocks: has to reference an ALP clock
|
|
- #clock-cells: should be <0>
|
|
- clock-output-names: from common clock bindings, should contain clock
|
|
name
|
|
|
|
Example:
|
|
|
|
pmu@18012000 {
|
|
compatible = "simple-mfd", "syscon";
|
|
reg = <0x18012000 0x00001000>;
|
|
|
|
ilp {
|
|
compatible = "brcm,bcm53573-ilp";
|
|
clocks = <&alp>;
|
|
#clock-cells = <0>;
|
|
clock-output-names = "ilp";
|
|
};
|
|
};
