-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>;
-	};
