13 Regulator nodes should be named to buck<number> and ldo<number>.
14
15 TI TPS65219 is a Power Management IC with 3 Buck regulators, 4 Low
16 Drop-out Regulators (LDOs), 1 GPIO, 2 GPOs, and power-button.
17
18 TI TPS65215 is a derivative of TPS65219 with 3 Buck regulators, 2 Low
19 Drop-out Regulators (LDOs), 1 GPIO, 1 GPO, and power-button.
20
21 TI TPS65214 is a derivative of TPS65219 with 3 Buck regulators, 2 Low
22 Drop-out Regulators (LDOs), 1 GPIO, 1 GPO, and power-button.

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