It was ported from linux v4.10. Like the kernel driver only
communication via I2C is supported.
It has only been tested with a SSD1306 and a 96x16 OLED display:
&i2c0 {
status = "okay";
ssd1306: oled@3c {
compatible = "solomon,ssd1306fb-i2c";
reg = <0x3c>;
reset-gpios = <&gpio1 1 0>;
solomon,height = <16>;
solomon,width = <96>;
solomon,page-offset = <0>;
solomon,com-invdir;
solomon,com-seq;
};

This patch changes the most part of mach-bcm2835 to mach-bcm283x. This
prepares to add RPi2 support which is a bcm2836. This patch changes the
Kconfig entry namens to BCM283X for drivers only. These drivers should
working the same in bcm2836.
While updating defconfig I added LED support/trigger option.

This patch realizes framebuffer console support for barebox. It
supports colors and enough escape sequences to show the barebox
console and editor properly.
fbconsole mini-HOWTO
====================
1. compile sandbox barebox with
CONFIG_VIDEO=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_DRIVER_VIDEO_SDL=y
2. run barebox
3. test fbconsole
fbconsole0.active=oe

This adds support for simple panels. These are panels which don't need
special handling but can have enable gpios and such. Unlike the Linux
kernel implementation this one is able to understand display-timings
nodes so that it's not necessary to keep a list of all known displays
with their corresponding timings in barebox.

The MTL017 is found on the Efika Smartbook. Not much is known about
this chip, so this driver only programs a register dump which is suitable
for some panels.

Complex video pipelines are modelled with the of_graph bindings in
the devicetree. This patch adds a ioctl infrastructure to issue
commands to the remote endpoint of a of_graph. Currently defined
ioctls are prepare/unprepare, enable/disable and get_modes. This
is enough to control LVDS or HDMI encoder or simple panels.
A device node which contains of_graph endpoints can be registered
as a VPL entity. An entity can receive ioctls via the .ioctl callback
and also issue ioctls by calling vpl_ioctl. The core itself will never
iterate over the entire pipeline. Instead, the different VPL entities
should forward an ioctl to the next instance in the pipeline whenever
necessary.

This will allow speed up the dev on framebuffer.
By default the resolution is VGA but this can be changed via cmdline.
We use a pthread to Flip the screen every 100ms as we can not detect when
