  12 description: |
  13   HiSilicon 6421v600 should be connected inside a MIPI System Power Management
  14   (SPMI) bus. It provides interrupts and power supply.
  15
  16   The GPIO and interrupt settings are represented as part of the top-level PMIC
  17   node.
  18
  19   The SPMI controller part is provided by
