+description: |
+  This module is part of the MAX77759 PMIC. For additional information, see
+  Documentation/devicetree/bindings/mfd/maxim,max77759.yaml.
+
+  The MAX77759 is a PMIC integrating, amongst others, Non Volatile Memory
+  (NVMEM) with 30 bytes of storage which can be used by software to store
+  information or communicate with a boot loader.
