| 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 | }; |
