    description: |
      The device exposes three DAIs, selected by index.
        0 - Standard Audio Path (Playback)
        1 - Low-Latency Playback Path (Playback)
        2 - Sensory Feedback (Capture - Vpredict and Isense)
      By default, all four channels of each DAI are active.

  interrupts:
    maxItems: 1
    description:
      Active-low falling-edge interrupt from the FAULT pin. When provided,
      the driver uses IRQ-driven fault reporting instead of polling.

  powerdown-gpios:
    maxItems: 1
    description:
      GPIO connected to the PD pin, active low. Controls the internal
      digital circuitry power state. When asserted the device enters
      full power-down mode and all register state is lost. Can be omitted if
      PD pin is hardwired or externally controlled.

  standby-gpios:
    maxItems: 1
    description:
      GPIO connected to the STBY pin, active low. Controls the analog
      power stage. When asserted the device enters Deep Sleep mode but
      remains I2C-accessible with registers retained. Can be omitted if
      STBY pin is tied to PD or hardwired.

  dvdd-supply:
    description:
      Digital logic supply (1.62 V to 3.6 V). All three supply rails must
      be within their recommended operating ranges before the PD pin is
      released.
