+* Amlogic AXG Audio Clock Controllers
+
+The Amlogic AXG audio clock controller generates and supplies clock to the
+other elements of the audio subsystem, such as fifos, i2s, spdif and pdm
+devices.
+
+Required Properties:
+
+- compatible	: should be "amlogic,axg-audio-clkc" for the A113X and A113D
+- reg		: physical base address of the clock controller and length of
+		  memory mapped region.
+- clocks	: a list of phandle + clock-specifier pairs for the clocks listed
+		  in clock-names.
+- clock-names	: must contain the following:
+		  * "pclk" - Main peripheral bus clock
+		  may contain the following:
+		  * "mst_in[0-7]" - 8 input plls to generate clock signals
+		  * "slv_sclk[0-9]" - 10 slave bit clocks provided by external
+				      components.
+		  * "slv_lrclk[0-9]" - 10 slave sample clocks provided by external
+				       components.
+- resets	: phandle of the internal reset line
+- #clock-cells	: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/axg-audio-clkc.h header and can be
+used in device tree sources.
+
+Example:
+
+clkc_audio: clock-controller@0 {
+	compatible = "amlogic,axg-audio-clkc";
+	reg = <0x0 0x0 0x0 0xb4>;
+	#clock-cells = <1>;
+
+	clocks = <&clkc CLKID_AUDIO>,
+		 <&clkc CLKID_MPLL0>,
+		 <&clkc CLKID_MPLL1>,
+		 <&clkc CLKID_MPLL2>,
+		 <&clkc CLKID_MPLL3>,
+		 <&clkc CLKID_HIFI_PLL>,
+		 <&clkc CLKID_FCLK_DIV3>,
+		 <&clkc CLKID_FCLK_DIV4>,
+		 <&clkc CLKID_GP0_PLL>;
+	clock-names = "pclk",
+		      "mst_in0",
+		      "mst_in1",
+		      "mst_in2",
+		      "mst_in3",
+		      "mst_in4",
+		      "mst_in5",
+		      "mst_in6",
+		      "mst_in7";
+	resets = <&reset RESET_AUDIO>;
