    1 Binding for Maxim MAX77686/MAX77802/MAX77620 32k clock generator block
    2 
    3 This is a part of device tree bindings of MAX77686/MAX77802/MAX77620
    4 multi-function device. More information can be found in MFD DT binding
    5 doc as follows:
    6         bindings/mfd/max77686.txt for MAX77686 and
    7         bindings/mfd/max77802.txt for MAX77802 and
    8         bindings/mfd/max77620.txt for MAX77620.
    9 
   10 The MAX77686 contains three 32.768khz clock outputs that can be controlled
   11 (gated/ungated) over I2C. Clocks are defined as preprocessor macros in
   12 dt-bindings/clock/maxim,max77686.h.
   13 
   14 
   15 The MAX77802 contains two 32.768khz clock outputs that can be controlled
   16 (gated/ungated) over I2C. Clocks are defined as preprocessor macros in
   17 dt-bindings/clock/maxim,max77802.h.
   18 
   19 The MAX77686 contains one 32.768khz clock outputs that can be controlled
   20 (gated/ungated) over I2C. Clocks are defined as preprocessor macros in
   21 dt-bindings/clock/maxim,max77620.h.
   22 
   23 Following properties should be presend in main device node of the MFD chip.
   24 
   25 Required properties:
   26 
   27 - #clock-cells: from common clock binding; shall be set to 1.
   28 
   29 Optional properties:
   30 - clock-output-names: From common clock binding.
   31 
   32 Each clock is assigned an identifier and client nodes can use this identifier
   33 to specify the clock which they consume. Following indices are allowed:
   34     - 0: 32khz_ap clock (max77686, max77802), 32khz_out0 (max77620)
   35     - 1: 32khz_cp clock (max77686, max77802),
   36     - 2: 32khz_pmic clock (max77686).
   37 
   38 Clocks are defined as preprocessor macros in above dt-binding header for
   39 respective chips.
