The Texas Instruments TAS5720L/M device is a high-efficiency mono Class-D audio power amplifier optimized for high transient power capability to use the dynamic power headroom of small loudspeakers. Its digital time division multiplexed (TDM) interface enables up to 16 devices to share the same bus.

There's no point in having interrupts-extended here with a single interrupt. It is fine to use, but really that's outside the scope of this binding. So I'd just document "interrupts" here as that is what most docs do, and that implies interrupts-extended could be used.
