+description: |
+  MT6397/MT6323 is a power management system chip.
+  Please see the sub-modules below for supported features.
+
+  MT6397/MT6323 is a multifunction device with the following sub modules:
+  - Regulators
+  - RTC
+  - Audio codec
+  - GPIO
+  - Clock
+  - LED
+  - Keys
+  - Power controller
+
+  It is interfaced to host controller using SPI interface by a proprietary hardware
+  called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap.
+  See the following for pwrap node definitions:
+  Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml
