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
20 Documentation/devicetree/bindings/spmi/hisilicon,hisi-spmi-controller.yaml
