| 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. |
