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. regulators: type: object description: | list of regulators provided by this controller patternProperties: "^ldo[1-4]$": type: object $ref: regulator.yaml# description: Properties for single LDO regulator. unevaluatedProperties: false "^buck[1-3]$": type: object $ref: regulator.yaml# description: Properties for single BUCK regulator. unevaluatedProperties: false additionalProperties: false patternProperties: "^buck[1-3]-supply$": description: Input supply phandle of one regulator.
