1* Amlogic audio memory arbiter controller
2
3The Amlogic Audio ARB is a simple device which enables or
4disables the access of Audio FIFOs to DDR on AXG based SoC.
5
6Required properties:
7- compatible: 'amlogic,meson-axg-audio-arb'
8- reg: physical base address of the controller and length of memory
9 mapped region.
10- clocks: phandle to the fifo peripheral clock provided by the audio
11 clock controller.
12- #reset-cells: must be 1.
13
14Example on the A113 SoC:
15
16arb: reset-controller@280 {
17 compatible = "amlogic,meson-axg-audio-arb";
18 reg = <0x0 0x280 0x0 0x4>;
19 #reset-cells = <1>;
20 clocks = <&clkc_audio AUD_CLKID_DDR_ARB>;
21};
