1* Amlogic Audio FIFO controllers
2
3Required properties:
4- compatible: 'amlogic,axg-toddr' or
5	      'amlogic,axg-toddr' or
6	      'amlogic,g12a-frddr' or
7	      'amlogic,g12a-toddr' or
8	      'amlogic,sm1-frddr' or
9	      'amlogic,sm1-toddr'
10- reg: physical base address of the controller and length of memory
11       mapped region.
12- interrupts: interrupt specifier for the fifo.
13- clocks: phandle to the fifo peripheral clock provided by the audio
14	  clock controller.
15- resets: list of reset phandle, one for each entry reset-names.
16- reset-names: should contain the following:
17  * "arb" : memory ARB line (required)
18  * "rst" : dedicated device reset line (optional)
19- #sound-dai-cells: must be 0.
20- amlogic,fifo-depth: The size of the controller's fifo in bytes. This
21  		      is useful for determining certain configuration such
22		      as the flush threshold of the fifo

24Example of FRDDR A on the A113 SoC:
25
26frddr_a: audio-controller@1c0 {
27	compatible = "amlogic,axg-frddr";
28	reg = <0x0 0x1c0 0x0 0x1c>;
29	#sound-dai-cells = <0>;
30	interrupts = <GIC_SPI 88 IRQ_TYPE_EDGE_RISING>;
31	clocks = <&clkc_audio AUD_CLKID_FRDDR_A>;
32	resets = <&arb AXG_ARB_FRDDR_A>;
33	fifo-depth = <512>;
34};
