Supply lcd not found, using dummy regulator [Yocto][imx6ul]

Hi all,

I'm trying to get a 8-bit interface TFT display working with imx6ul.

Therefore I have applied the following patch: Patch to support MPU 8080 LCD on iMX6UL and iMX7D 

When booting the Kernel gives me the following log:

MIPI DSI driver module loaded

21c8000.lcdif supply lcd not found, using dummy regulator
MIPI DSI driver module loaded

mxsfb 21c8000.lcdif: failed to find mxc display driver
Console: switching to colour frame buffer device 30x40
mxsfb 21c8000.lcdif: initialized

How should I start to fix this issue?

I have looked to activate the display in U-boot but unfortunately this is not an option as the u-boot version used for my specific board does not include any LCDIF options.

Kind regards

Hi Jasper

i.MX6UL does not have mipi-dsi, please try to remove it from linux build.

Best regards
igor

Done, but as expected this does not change the situation... Any more advice?
