- The IP supports I2S playback/capture audio. It acts as a slave and
- clocks should come from the codec. It only supports two channels and
- S16_LE format.

Base address and size of the IP core instance.

Either the Tx interruption or the Rx interruption or both.
The schema says either tx or both. Doesn't really matter here as it's just numbers.
- interrupt-names:
- minItems: 1
- maxItems: 2
- items:
- const: tx
- const: rx
But here it does matter.
The easiest way to express this is:
oneOf: - items: - enum: [ tx, rx ] - items: - const: tx - const: rx
+required:
- compatible
- reg
- interrupts
- interrupts-controller

- logii2s_dai: logii2s-dai@43c10000 {
reg = <0x43c10000 0x1000>;
compatible = "xlnx,logicpd-i2s-dai";
interrupt-parent = <&intc>;
interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "rx", "tx";
