BD96802Qxx-C is an automotive grade configurable Power Management
Integrated Circuit supporting Functional Safety features for application
processors, SoCs and FPGAs. BD96802 is controlled via I2C, provides two
interrupt lines and has two controllable buck regulators.

The BD96802 belongs to the family of ROHM Scalable PMICs and is intended
to be used as a companion PMIC for the BD96801.

+description:
+  This module is part of the ROHM BD96802 MFD device. For more details
+  see Documentation/devicetree/bindings/mfd/rohm,bd96802-pmic.yaml.
+
+  The regulator controller is represented as a sub-node of the PMIC node
+  on the device tree.
+
+  Regulator nodes should be named to buck1 and buck2.
