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