+Name:   watterott-display
+Info:   Watterott RPi-Display - 2.8" Touch Display
+        Linux has 2 drivers that support this display and this overlay supports
+        both.
+
+        Examples:
+          fbtft/fb_ili9341: dtoverlay=watterott-display
+          drm/mi0283qt: dtoverlay=watterott-display,drm,backlight-pwm,rotate=180
+
+        Some notable differences with the DRM driver compared to fbtft:
+        - The display is turned on when it's first used and not on driver load
+          as with fbtft. So if nothing uses the display it stays off.
+        - Can run with a higher SPI clock increasing framerate. This is possible
+          since the driver avoids messing up the controller configuration due to
+          transmission errors by running config commands at 10MHz and only pixel
+          data at full speed (occasional pixel glitch might occur).
+        - PWM backlight is supported.

+                                This has to be the first parameter.
+        backlight-pwm           Use pwm for backlight (drm only). NB: Disables
+                                audio headphone output as that also uses PWM.
