title: Peripheral-specific properties for a Memory Controller bus.

description:
  Many Memory Controllers need to add properties to peripheral devices.
  They could be common properties like reg or they could be controller
  specific like delay in clock or data lines, etc. These properties need
  to be defined in the peripheral node because they are per-peripheral
  and there can be multiple peripherals attached to a controller. All
  those properties are listed here. The controller specific properties
  should go in their own separate schema that should be referenced
  from here.

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.
