Hello,
we have the Freescale IMX27-PDK demo kit. Along with it, we got the
source code for the linux kernel version 2.6.22, and a lot of patches.
Also for the video part, there are a lot of patches, creating a
/drivers/video/mxc subdirectory.
In the linux sources 2.6.37, I only find 2 files: mx3fb.c (imx3x i
guess) and imxfb.c.
When we try to compile linux for the imx27 (with the latest ltib) there
are no framebuffers under devices.
Do I still need to patch linux/drivers/video for the imx27, or should it
work fine like it is?
(and if so, what do I do wrong ;-)
Kind regards,
Juergen

Framebuffer support for MX27 is available at: drivers/video/imxfb.c
You can also take a look at arch/arm/mach-imx/mach-mx27ads.c to see an
example of a MX27 based board with framebuffer support.

In vanilla/mainline kernel, imxfb.c handles both MX1 and MX2 LCD
controllers.
