   7 title: Peripheral-specific properties for a Memory Controller bus.
   8
   9 description:
  10   Many Memory Controllers need to add properties to peripheral devices.
  11   They could be common properties like reg or they could be controller
  12   specific like delay in clock or data lines, etc. These properties need
  13   to be defined in the peripheral node because they are per-peripheral
  14   and there can be multiple peripherals attached to a controller. All
  15   those properties are listed here. The controller specific properties
  16   should go in their own separate schema that should be referenced
  17   from here.
