+Subject: [PATCH] arm: dts: overlays: pitft35-resistive: add upstream
+ compatible
+
+The upstream hx8357d driver uses "adafruit,yx350hv15" for the compatible
+string explicitly for this screen config and not a hx8357d generic for
+the controller so add that in as well so it will work with an unmodified
+upstream kernel driver. We leave the downstream as the priority.
