Noralf Trønnes edited this page Jan 7, 2020 · 27 revisions

Generic driver for various LCD Controllers.

Note: flexfb is not available starting from Linux 5.4

This driver tries to be a solution for the many LCD Controllers available, without having to write drivers for them all.
One strength is that it is runtime configurable. Download image and start using with an "unsupported" display.

The driver supports both SPI devices: flexfb and platform devices: flexpfb. fbtft_device has support for both.
