-* Amlogic Audio FIFO controllers
-
-Required properties:
-- compatible: 'amlogic,axg-toddr' or
- 'amlogic,axg-toddr' or
- 'amlogic,g12a-frddr' or
- 'amlogic,g12a-toddr' or
- 'amlogic,sm1-frddr' or
- 'amlogic,sm1-toddr'
-- 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: list of reset phandle, one for each entry reset-names.
-- reset-names: should contain the following:
- * "arb" : memory ARB line (required)
- * "rst" : dedicated device reset line (optional)
-- #sound-dai-cells: must be 0.
-- amlogic,fifo-depth: The size of the controller's fifo in bytes. This
- is useful for determining certain configuration such
- as the flush threshold of the fifo
-
-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>;
- fifo-depth = <512>;
-};
