Linux Framebuffer drivers for small TFT LCD display modules.

For a list of all wikipages see Pages

fbtft_device and flexfb are gone in 5.4

fbtft_device was removed because the gpio code had been reworked without fixing up fbtft_device so it didn't work. fbtft_device was never intended to be included in mainline and has survived for this long since "no-one" knew that it was a pure device adder module, which doesn't belong in mainline.
flexfb was removed because it will never be ported to the DRM graphics subsystem due to its nature. The init= DT property is not accepted.
fbtft will now only work with Device Tree due to the above mentioned disruptive gpio rework. See the Device-Tree page.
fbtft is currently listed as orphaned in MAINTANERS so it doesn't have someone looking after it, at least officially.

See /boot/overlays/README and FBTFT RPI overlays for information about Device Tree overlays.

Thanks

Without the help from other people, this project would not exist

Matt Porter wrote st7735fb which FBTFT grew from
Texy has provided much input and testing that have helped move this project forward
Derek Campbell did the work to implement DMA
Several people have provided drivers and improvements

Also thanks to people that help answering questions about FBTFT.
