Hi Biser,
The question is more AM335x specific than WL1x as I'm seeing this as an "active high" pin for controlling an external IC's ENable pi or gate on a transistor during deepsleep0.
The patch I'm refering to has only to do with an errata for the AM335x eval-board during suspend loosing it's context.
I think it would be great if we could see an answer here.
best David
