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/mfd/hisilicon,hi6421-spmi-pmic.yaml
