10 The MAX77686 contains three 32.768khz clock ou
11 (gated/ungated) over I2C. Clocks are defined a
12 dt-bindings/clock/maxim,max77686.h.
13
14
15 The MAX77802 contains two 32.768khz clock outp
16 (gated/ungated) over I2C. Clocks are defined a
17 dt-bindings/clock/maxim,max77802.h.
18
19 The MAX77686 contains one 32.768khz clock outp
20 (gated/ungated) over I2C. Clocks are defined a
21 dt-bindings/clock/maxim,max77620.h.
22
23 Following properties should be presend in main
24
25 Required properties:
26
27 - #clock-cells: from common clock binding; sha
28
29 Optional properties:
30 - clock-output-names: From common clock bindin
31
32 Each clock is assigned an identifier and clien
33 to specify the clock which they consume. Follo
34 - 0: 32khz_ap clock (max77686, max77802),
35 - 1: 32khz_cp clock (max77686, max77802),
36 - 2: 32khz_pmic clock (max77686).
37
38 Clocks are defined as preprocessor macros in a
39 respective chips.
