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	
13	- #clock-cells: from common clock binding; shall be set to 1.
14	
15	Optional properties:
16	- clock-output-names: From common clock binding.
17	
18	Each clock is assigned an identifier and client nodes can use this identifier
19	to specify the clock which they consume. Following indices are allowed:
20	    - 0: 32khz_ap clock,
21	    - 1: 32khz_cp clock,
22	    - 2: 32khz_pmic clock.
23	
24	Clocks are defined as preprocessor macros in dt-bindings/clock/maxim,max77686.h
25	header and can be used in device tree sources.
26	
27	Example: Node of the MFD chip
28	
29		max77686: max77686@09 {
30			compatible = "maxim,max77686";
31			interrupt-parent = <&wakeup_eint>;
32			interrupts = <26 0>;
33			reg = <0x09>;
34			#clock-cells = <1>;
35	
36			/* ... */
37		};
38	
39	Example: Clock consumer node
40	
41		foo@0 {
42			compatible = "bar,foo";
43			/* ... */
44			clock-names = "my-clock";
45			clocks = <&max77686 MAX77686_CLK_PMIC>;
46		};
