+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.
