+From fe90ee51b283f7cbbce9980b76b3da8b31d39c60 Mon Sep 17 00:00:00 2001
+From: MikeDK <m.kaplan@evva.com>
+Date: Fri, 31 Jan 2020 10:57:21 +0100
+Subject: [PATCH] overlays: Add ssd1306-spi, ssh1106-spi, ssd-1351-spi
+
+Add overlays for SSD1306, SH1106 and SSD1351 based OLED displays.
+SH1106 is present in many 1.3 inch OLEDs and SSD1351 is present in
+1.5 inch RGB OLEDs from AliExpress.
+
+This will load the staging fbtft drivers.
+
+Signed-off-by: Michael Kaplan <m.kaplan@evva.com>
