Describe required properties and regname-supply. regname-supply is required when bypass mode is used for a regulator. Describes regulator topology. Interrupts support. Add a power-button property to configure the EN/PB/VSENSE pin as a powerbutton: TPS65219 has a multipurpose pin called EN/PB/VSENSE that can be either: - EN in which case it functions as an enable pin. - VSENSE which compares the voltages and triggers an automatic on/off request. - 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.
