* Amlogic Audio FIFO controllers
Required properties:
- compatible: 'amlogic,axg-toddr' or
'amlogic,axg-frddr'
- reg: physical base address of the controller and length of memory
mapped region.
- interrupts: interrupt specifier for the fifo.
- clocks: phandle to the fifo peripheral clock provided by the audio
clock controller.
- resets: phandle to memory ARB line provided by the arb reset controller.
- #sound-dai-cells: must be 0.
Example of FRDDR A on the A113 SoC:
frddr_a: audio-controller@1c0 {
compatible = "amlogic,axg-frddr";
reg = <0x0 0x1c0 0x0 0x1c>;
#sound-dai-cells = <0>;
interrupts = <GIC_SPI 88 IRQ_TYPE_EDGE_RISING>;
clocks = <&clkc_audio AUD_CLKID_FRDDR_A>;
resets = <&arb AXG_ARB_FRDDR_A>;
};
