    Subject[PATCH v3 04/10] regulator: dt-bindings: Add TI TPS65219 PMIC bindings
    Date
    Add TPS65219 PMIC bindings using json-schema.

    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.
