-* 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' or
- 'amlogic,meson-sm1-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>;
-};
