 12description: |
 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
 20  Documentation/devicetree/bindings/spmi/hisilicon,hisi-spmi-controller.yaml
