flexfb

Generic driver for various LCD Controllers.

Note: This approach to one driver to rule them all, has been abandoned. Now it is the usual one driver per chip.

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.
