[PATCH 0/1] ARM: dts: sunxi: Add simplefb nodes for de_be0-lcd0, de_be0-lcd0-tve0

[Hans de Goede]

Hi Maxime,

As you may have noticed on the u-boot list, I've been working on adding
support for getting a graphical u-boot console up on sunxi LCD and VGA outputs.

The main reason behind this is so that people can see u-boot (error) messages
without needing to solder a serial console onto tablets (and other boards),
hopefully we will get otg support in the near future too, and then people can
interact with upstream u-boot without needing to open their tablet.

Getting the kernel to work with LCD / VGA output setup by u-boot requires
adding pre-populated simplefb nodes for a display pipeline of de_be0-lcd0
(for LCD) resp. de_be0-lcd0-tve0 (for VGA), this patch adds the necessary
nodes. With this patch the kernel can use LCD / VGA outputs setup by u-boot.

LCD output has been tested on various Olinuxino boards with the 7" Olimex LCD
module, and on a 7" LCD of an A23 tablet, it has also been successfully tested
by both ChenYu and Siarhei on other tablets.

VGA output has been tested on a Cubietruck, A20-Olinuxino-Micro and a Mele-M3.

Regards,

Hans

[PATCH] ARM: dts: sunxi: Add simplefb nodes for de_be0-lcd0, de_be0-lcd0-tve0 pipelines

[Hans de Goede]

Add simplefb nodes for "de_be0-lcd0" and "de_be0-lcd0-tve0" display pipeline
for when u-boot has set up a pipeline to drive a LCD panel / VGA output rather
then the HDMI output.
