1Binding for Maxim MAX77686 32k clock generator block 2 3This is a part of device tree bindings of MAX77686 multi-function device. 4More information can be found in bindings/mfd/max77686.txt file. 5 6The MAX77686 contains three 32.768khz clock outputs that can be controlled 7(gated/ungated) over I2C. 8 9Following properties should be presend in main device node of the MFD chip. 10 11Required properties: 12 13- #clock-cells: from common clock binding; shall be set to 1. 14 15Optional properties: 16- clock-output-names: From common clock binding. 17 18Each clock is assigned an identifier and client nodes can use this identifier 19to 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 24Clocks are defined as preprocessor macros in dt-bindings/clock/maxim,max77686.h 25header and can be used in device tree sources. 26 27Example: 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 39Example: Clock consumer node 40 41 foo@0 { 42 compatible = "bar,foo"; 43 /* ... */ 44 clock-names = "my-clock"; 45 clocks = <&max77686 MAX77686_CLK_PMIC>; 46 }; 47
