* 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>;
};
