-+Name: ssd1306
-+Info: Overlay for activation of SSD1306 over I2C OLED display framebuffer.
-+Load: dtoverlay=ssd1306,<param>=<val>
-+Params: address Location in display memory of first character.
-+ (default=0)
-+ width Width of display. (default=128)
-+ height Height of display. (default=64)
-+ offset virtual channel a. (default=0)
-+ normal Has no effect on displays tested. (default=not
-+ set)
-+ sequential Set this if every other scan line is missing.
-+ (default=not set)
-+ remapped Set this if display is garbled. (default=not
-+ set)
-+ inverted Set this if display is inverted and mirrored.
-+ (default=not set)
-+
-+ Examples:
-+ Typical usage for 128x64 display: dtoverlay=ssd1306,inverted
-+
-+ Typical usage for 128x32 display: dtoverlay=ssd1306,inverted,sequential
-+
-+ i2c_baudrate=400000 will speed up the display.
-+
-+ i2c_baudrate=1000000 seems to work even though it's not officially
-+ supported by the hardware, and is faster still.
-+
-+ For more information refer to the device datasheet at:
-+ https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf
