+Name:   fbtft
+Info:   Overlay for SPI-connected displays using the fbtft drivers.
+
+        This overlay seeks to replace the functionality provided by fbtft_device
+        which is now gone from the kernel.
+
+        Most displays from fbtft_device have been ported over.
+        Example:
+          dtoverlay=fbtft,spi0-0,rpi-display,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
+
+        It is also possible to specify the controller (this will use the default
+        init sequence in the driver).
+        Example:
+          dtoverlay=fbtft,spi0-0,ili9341,bgr,reset_pin=23,dc_pin=24,led_pin=18,rotate=270
+
+        For devices on spi1 or spi2, the interfaces should be enabled
+        with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
+
+        The following features of fbtft_device have not been ported over:
+        - parallel bus is not supported
+        - the init property which overrides the controller initialization
+          sequence is not supported as a parameter due to memory limitations in
+          the bootloader responsible for applying the overlay.
+
+        See https://github.com/notro/fbtft/wiki/FBTFT-RPI-overlays for how to
+        create an overlay.
