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.

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.
