+Subject: [PATCH 700/703] overlays: Add real parameters to the rpi-poe overlay
+
+As a result of being loaded by the POE HAT EEPROM, the rpi-poe overlay
+doesn't expose parameters in the usual way; instead it adds them to
+the base Device Tree, and the user is expected to use "dtparam=..."
+to access them.
+
+To make the documentation correct and to protect users who load the
+overlay explicitly, expecting to be able to use the parameters, add
+real parameters to the overlay as well.
