-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 provide 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.
-
-Example:
-
- #include <dt-bindings/clock/maxim,max9485.h>
-
- xo-27mhz: xo-27mhz {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <27000000>;
- };
-
- &i2c0 {
- max9485: audio-clock@63 {
- reg = <0x63>;
- compatible = "maxim,max9485";
- clock-names = "xclk";
- clocks = <&xo-27mhz>;
- reset-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
- vdd-supply = <&3v3-reg>;
- #clock-cells = <1>;
- };
- };
-
- // Clock consumer node
-
- foo@0 {
- compatible = "bar,foo";
- /* ... */
- clock-names = "foo-input-clk";
- clocks = <&max9485 MAX9485_CLKOUT1>;
