* 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>;
|
||
|
|
};
