  Rockchip RK806 series PMIC. This device consists of an spi or

    description:
      Mode to use when a reset of the PMIC is triggered.

      The reset can be triggered either programmatically, via one of
      the PWRCTRL pins (provided additional configuration) or
      asserting RESETB pin low.

      The following modes are supported

      - 0; restart PMU,
      - 1; reset all power off reset registers and force state to
        switch to ACTIVE mode,
      - 2; same as mode 1 and also pull RESETB pin down for 5ms,

      For example, some hardware may require a full restart (mode 0)
      in order to function properly as regulators are shortly
      interrupted in this mode.
