      The first cell is the IRQ number. The second cell is the flags,
      encoded as trigger masks from ../interrupt-controller/interrupts.txt.

    description: |
      The first cell is the pin number and the second cell is used to specify
      flags.  See ../gpio/gpio.txt for more information.

      List of child nodes that specify the regulator initialization data.
      Child nodes must be named after their hardware counterparts:
      buck[1-6], ldoa[1-3], swa1, swb[1-2], and vtt.
      Each child node is defined using the standard binding for regulators and
      the optional regulator properties defined below.

            description: |
              Set this if the regulator is factory set with a 25mv step voltage
              mapping.

            description: |
              Set this if the output needs to decay, default is for the output
              to slew down.
