   4 Subject: [PATCH 696/725] overlays: Add real parameters to the rpi-poe overlay
   5
   6 As a result of being loaded by the POE HAT EEPROM, the rpi-poe overlay
   7 doesn't expose parameters in the usual way; instead it adds them to
   8 the base Device Tree, and the user is expected to use "dtparam=..."
   9 to access them.
  10
  11 To make the documentation correct and to protect users who load the
  12 overlay explicitly, expecting to be able to use the parameters, add
  13 real parameters to the overlay as well.
