@lex, to get timings for panel you need to follow instructions on
https://linux-sunxi.org/LCD (see "FEX conversion rules"). I understand
that's pretty boring, but that's the only reliable way I know.
I would recommend to start by making your panel to work under u-boot.
U-boot has to be
Hi Andrey,
I have found my fex file for an 18.4" Panel. I have a hard time to figure
out how to enable the dual channel in the dts, can you have a look at it
and help how to enable it?
Here are the timings:
[lcd0_para]
lcd_used = 1
lcd_x = 1920
lcd_y = 1080
lcd_dclk_freq = 69
lcd_pwm_not_used
Hi Andrey,
Thank you for sharing your work.
I can remember 2 channel was needed for the 1920x1080 res. in fact the
panel is 17"
I need to find the fex files, must be somewhere here... :)
I will try with your kernel and see what i get. Busy weekend ahead...
I will post the results.

Hi Andrey,
I have a couple of 15" LCDs (different makers) with Cubieboard A20 (kernel
3.4) i would like to test your implementation if possible.
Can you share a kernel tree with your code and where should i change the
timings for each Panel?
