-	  Add support for HiSilicon Hi6421v600 SPMI PMIC. Hi6421 includes

-
-	  This driver includes core APIs _only_. You have to select
-	  individual components like voltage regulators under corresponding
-	  menus in order to enable them.
-	  We communicate with the Hi6421v600 via a SPMI bus.

-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
