1 Devicetree bindings for Maxim MAX9485 Programm
2
3 This device exposes 4 clocks in total:
4
5 - MAX9485_MCLKOUT: A gated, buffered outp
6 - MAX9485_CLKOUT: A PLL that can be conf
7 frequencies
8 - MAX9485_CLKOUT[1,2]: Two gated outputs for
9
10 MAX9485_CLKOUT[1,2] are children of MAX9485_CL
11 requests.
12
13 Required properties:
14 - compatible: "maxim,max9485"
15 - clocks: Input clock, must provide 27.0
16 - clock-names: Must be set to "xclk"
17 - #clock-cells: From common clock binding; sha
18
19 Optional properties:
20 - reset-gpios: GPIO descriptor connec
21 - vdd-supply: A regulator node for V
22 - clock-output-names: Name of output clocks,
23 bindings
24
25 If not explicitly set, the output names are "m
26 and "clkout2".
27
28 Clocks are defined as preprocessor macros in t
