+* Amlogic audio memory arbiter controller
+
+The Amlogic Audio ARB is a simple device which enables or
+disables the access of Audio FIFOs to DDR on AXG based SoC.
+
+Required properties:
+- compatible: 'amlogic,meson-axg-audio-arb'
+- reg: physical base address of the controller and length of memory
+ mapped region.
+- clocks: phandle to the fifo peripheral clock provided by the audio
+ clock controller.
+- #reset-cells: must be 1.
+
+Example on the A113 SoC:
+
+arb: reset-controller@280 {
+ compatible = "amlogic,meson-axg-audio-arb";
+ reg = <0x0 0x280 0x0 0x4>;
+ #reset-cells = <1>;
+ clocks = <&clkc_audio AUD_CLKID_DDR_ARB>;
+};
