title: Rejected, Legacy or Incomplete Devices

description:
  Some devices will not or should not get a proper Devicetree bindings, but
  their compatibles are present in Linux drivers for various reasons.
 
  Examples are devices using ACPI PRP0001 with non-updatable firmware/ACPI
  tables or old PowerPC platforms without in-tree DTS.
 
  Following list of devices is an incomplete schema with a goal to pass DT schema
  checks on undocumented compatibles but also reject any DTS file using such
  un-approved compatible.
 
  Usage of any of following compatibles is not allowed in Devicetree sources,
  even if they come from immutable firmware.
