Do I need to control the W_DISABLE# signal on the Sona TI351?

Answer

Yes, there is a watchdog mechanism in the Sona TI351 that will detect an issue and reset the radio. To accomplish this, there needs to be GPIO control over the W_DISABLE# signal. This is typically implemented with a regulator construct in the device tree.

Please see the Sona TI Software Integration Guide for more information and a sample Device Tree.
