+title: HiSilicon 6421v600 SPMI PMIC
+
+maintainers:
+ - Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
+
+description: |
+ HiSilicon 6421v600 should be connected inside a MIPI System Power Management
+ (SPMI) bus. It provides interrupts and power supply.
+
+ The GPIO and interrupt settings are represented as part of the top-level PMIC
+ node.
+
+ The SPMI controller part is provided by
+ Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml
