1 | Binding for Maxim MAX77686 32k clock generator block | ||
2 | |||
3 | This is a part of device tree bindings of MAX77686 multi-function device. | ||
4 | More information can be found in bindings/mfd/max77686.txt file. | ||
5 | |||
6 | The MAX77686 contains three 32.768khz clock outputs that can be controlled | ||
7 | (gated/ungated) over I2C. | ||
8 | |||
9 | Following properties should be presend in main device node of the MFD chip. | ||
10 | |||
11 | Required properties: | ||
12 | - #clock-cells: simple one-cell clock specifier format is used, where the | ||
13 | only cell is used as an index of the clock inside the provider. Following | ||
14 | indices are allowed: | ||
15 | - 0: 32khz_ap clock, | ||
16 | - 1: 32khz_cp clock, | ||
17 | - 2: 32khz_pmic clock. | ||
18 | |||
19 | Example: Node of the MFD chip | ||
20 | |||
21 | max77686: max77686@09 { | ||
22 | compatible = "maxim,max77686"; | ||
23 | interrupt-parent = <&wakeup_eint>; | ||
24 | interrupts = <26 0>; | ||
25 | reg = <0x09>; | ||
26 | #clock-cells = <1>; | ||
27 | |||
28 | /* ... */ | ||
29 | }; | ||
30 | |||
31 | Example: Clock consumer node | ||
32 | |||
33 | foo@0 { | ||
34 | compatible = "bar,foo"; | ||
35 | /* ... */ | ||
36 | clock-names = "my-clock"; | ||
37 | clocks = <&max77686 2>; | ||
