1*4882a593Smuzhiyun* Amlogic audio memory arbiter controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe Amlogic Audio ARB is a simple device which enables or
4*4882a593Smuzhiyundisables the access of Audio FIFOs to DDR on AXG based SoC.
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunRequired properties:
7*4882a593Smuzhiyun- compatible: 'amlogic,meson-axg-audio-arb' or
8*4882a593Smuzhiyun	      'amlogic,meson-sm1-audio-arb'
9*4882a593Smuzhiyun- reg: physical base address of the controller and length of memory
10*4882a593Smuzhiyun       mapped region.
11*4882a593Smuzhiyun- clocks: phandle to the fifo peripheral clock provided by the audio
12*4882a593Smuzhiyun	  clock controller.
13*4882a593Smuzhiyun- #reset-cells: must be 1.
14*4882a593Smuzhiyun
15*4882a593SmuzhiyunExample on the A113 SoC:
16*4882a593Smuzhiyun
17*4882a593Smuzhiyunarb: reset-controller@280 {
18*4882a593Smuzhiyun	compatible = "amlogic,meson-axg-audio-arb";
19*4882a593Smuzhiyun	reg = <0x0 0x280 0x0 0x4>;
20*4882a593Smuzhiyun	#reset-cells = <1>;
21*4882a593Smuzhiyun	clocks = <&clkc_audio AUD_CLKID_DDR_ARB>;
