-From c46811a3b0e0fb76015ac956172e40bce4e6d9b3 Mon Sep 17 00:00:00 2001
-From: Phil Elwell <pelwell@users.noreply.github.com>
-Date: Fri, 5 Jul 2019 14:49:22 +0100
-Subject: [PATCH 694/806] overlays: Rename pi3- overlays to be less
- model-specific (#3052)
-
-Rename the various pi3- overlays to be more generic, listing
-the devices they apply to in the README. The original names are
-retained for backwards compatibility as files that just include
-the new versions - the README marks them as being deprecated.
-
-See: https://github.com/raspberrypi/firmware/issues/1174
