| 42 | + Optional property that sets the EN/PB/VSENSE pin to be a |
| 43 | + power-button. |
| 44 | + TPS65219 has a multipurpose pin called EN/PB/VSENSE that can be either |
| 45 | + 1. EN in which case it functions as an enable pin. |
| 46 | + 2. VSENSE which compares the voltages and triggers an automatic |
| 47 | + on/off request. |
| 48 | + 3. PB in which case it can be configured to trigger an interrupt |
| 49 | + to the SoC. |
| 50 | + ti,power-button reflects the last one of those options |
| 51 | + where the board has a button wired to the pin and triggers |
| 52 | + an interrupt on pressing it. |
