+         Add support for HiSilicon Hi6421v600 SPMI PMIC. Hi6421 includes
+         multi-functions, such as regulators, RTC, codec, Coulomb counter,
+         etc.
+
+         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.
