   3 Subject: [PATCH] dt: bindings: net: add bindings for QCN6122
   4
   5 QCN6122 is a PCIe based solution that is attached to and enumerated
   6 by the WPSS (Wireless Processor SubSystem) Q6 processor.
   7
   8 Though it is a PCIe device, since it is not attached to APSS processor
   9 (Application Processor SubSystem), APSS will be unaware of such a decice
  10 and hence it is registered to the APSS processor as a platform device(AHB).
  11 Because of this hybrid nature, it is called as a hybrid bus device.
  12
  13 As such, QCN6122 is a hybrid bus type device and follows the same codepath
  14 as for WCN6750.
  15
  16 This is a reversed engineered and heavily simplified version of below
