No, there is a difference between system-power-controller and power-button. If you ask, my description is probably not clear enough. Let me try a new one: TPS65219 has a multipurpose pin called EN/PB/VSENSE that can be either EN in which case it functions as an enable pin. It can be VSENSE which compares the voltages and triggers an automatic on/off request. And it can be PB in which case it can be configured to trigger an interrupt to the SoC. ti,power-button reflects exactly the last one of those options where the board has a button wired to the pin and triggers an interrupt on pressing it. I hope that answers your question. We will fix the description in v2.
