of audio samples.

-
"irq_mm2s" : interrupt from MM2S block
12
-
"irq_s2mm" : interrupt from S2MM block
13
-
- interrupts-parent: Phandle for interrupt controller.
14
-
- interrupts: List of Interrupt numbers.
15
-
- reg: Base address and size of the IP core instance.
16
-
- clock-names: List of input clocks.
17
-
Required elements: "s_axi_lite_aclk", "aud_mclk"
18
-
- clocks: Input clock specifier. Refer to common clock bindings.
