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