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.
