The TAS6424 incorporates both DC-load and AC-load diagnostics which are
used to determine the status of the load. The DC diagnostics runs when any
channel is directed to leave the Hi-Z state and enter the MUTE or PLAY
state.
The DC diagnostics are turned on by default but, if a fast startup without
diagnostics is required, the diagnostics can be disabled using a dedicated
ALSA control.

mute can be connected to GPIO. In that case we have to drive it to the
correct value

The standby pin can be connected to a GPIO. In that case we have to drive
it to the correct values for the TAS6424 to operate properly.

The Texas Instruments TAS6424 device is a high-efficiency quad-channel
Class-D audio power amplifier. Its digital time division multiplexed
(TDM) interface enables up to 2 devices to share the same bus,
supporting a total of eight channels from one audio serial port.
