   3 Date: Fri, 31 Jan 2020 10:57:21 +0100
   4 Subject: [PATCH] overlays: Add ssd1306-spi, ssh1106-spi, ssd-1351-spi
   5
   6 Add overlays for SSD1306, SH1106 and SSD1351 based OLED displays.
   7 SH1106 is present in many 1.3 inch OLEDs and SSD1351 is present in
   8 1.5 inch RGB OLEDs from AliExpress.
   9
  10 This will load the staging fbtft drivers.
