      Enable the regulator framework so power supplies described in the device
      tree can be registered, referenced, and controlled at runtime. With this
      selected, drivers may obtain regulators via `rt_regulator_get()`, request
      enable/disable, or vote for specific voltage/current levels before their
      peripherals start. The framework depends on the driver-model and ADT
      parser because it walks the same device tree phandles. Disable it only
      when the SoC has no controllable supplies and every peripheral is powered
      permanently.

    help
      Provide the "fixed" regulator type in which the output voltage is defined
      entirely by the hardware (for example a PMIC LDO) and RT-Thread can only
      toggle an optional GPIO enable pin. The driver parses standard device tree
      properties such as `startup-delay-us`, `off-on-delay-us`, `enable-active-
      high`, and also applies any pinctrl state before asserting the output.
      Select this when the board DTS contains `regulator-fixed` nodes; it is
      safe to leave enabled because it only instantiates devices that the DT
      describes.

config RT_REGULATOR_GPIO
    bool "GPIO regulator support"
    depends on RT_USING_REGULATOR
    depends on RT_USING_PIN
    default y
    help
      Allow the framework to emulate simple DAC-like regulators using GPIO banks
      where each output bit selects a discrete voltage/current point. The
      driver reads the `states` table from the device tree and programs the GPIO
      pins accordingly, so peripheral drivers can call `set_voltage()` and let
      the framework choose the closest valid entry. Enable this when your board
      uses GPIO strapping to select regulator levels (common with analog muxes)
      or PMIC power modes; otherwise it adds no runtime cost.
