-* 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,
-		  "amlogic,g12a-audio-clkc" for G12A,
-		  "amlogic,sm1-audio-clkc" for S905X3.
-- 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.
-- #reset-cells  : should be 1 on the g12a (and following) soc family
-
-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>;
