Devicetree bindings for Maxim MAX9485 Programmable Audio Clock Generator
|
||||
|
||||
This device exposes 4 clocks in total:
|
||||
|
||||
- MAX9485_MCLKOUT: A gated, buffered output of the input clock of 27 MHz
|
||||
- MAX9485_CLKOUT: A PLL that can be configured to 16 different discrete
|
||||
frequencies
|
||||
- MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT
|
||||
|
||||
MAX9485_CLKOUT[1,2] are children of MAX9485_CLKOUT which upchain all rate set
|
||||
requests.
|
||||
|
||||
Required properties:
|
||||
- compatible: "maxim,max9485"
|
||||
- clocks: Input clock, must provice 27.000 MHz
|
||||
- clock-names: Must be set to "xclk"
|
||||
- #clock-cells: From common clock binding; shall be set to 1
|
||||
|
||||
Optional properties:
|
||||
- reset-gpios: GPIO descriptor connected to the #RESET input pin
|
||||
- vdd-supply: A regulator node for Vdd
|
||||
- clock-output-names: Name of output clocks, as defined in common clock
|
||||
bindings
|
||||
|
||||
If not explicitly set, the output names are "mclkout", "clkout", "clkout1"
|
||||
and "clkout2".
|
||||
|
||||
Clocks are defined as preprocessor macros in the dt-binding header.

||||

||||
