description: |
  This module is part of the ROHM BD71828 MFD device. For more details
  see Documentation/devicetree/bindings/mfd/rohm,bd71828-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 BUCK_<number> and LDO_<number>.
  The valid names for BD71828 regulator nodes are
  BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7
  LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
