<s3b0> hi, i have problem with this panel S070SWV20HG-DC16 under Lamobo R1(BPIR1)
<s3b0> on u-boot it works
<s3b0> but as soon linux loads it stoips working
<s3b0> you can see it here
<s3b0> i think it is becouse of lack of drivers (sunxi-lcd) in mainline kernel
<s3b0> because
<s3b0> on stock kernel sunxi 3.4 it works
<s3b0> u-boot has this drivers and that is why it works with this panel
<s3b0> could anyone know how to fix it? Or can guide me how i can port this driver to mainline(i completely noob int kernel programming but i can try ;))

<gamiee> s3bo: hmm, do you have correct device tree? It's weird that u-boot supports it and kernel doesn'

<s3b0> gamiee: i tried several dtses - all of them failed (not worked)
<s3b0> this one should work but it doesn't https://github.com/wens/dt-overlays/blob/master/bpi-m1p-lcd.dts
<s3b0> weirdest think is that on old(sunxi 3.4) kernel it works
<s3b0> so it is not hardware issue
<s3b0> overlay mentioned above is for s070wv20-ct16 and i have different panel
<s3b0> also 7" and 800x480 but part number is different
<s3b0> S070SWV20HG-DC16

<s3b0> don't know what is the difference - i couldn't find data-sheet for it

<s3b0> btw. manufacturer is cdtech (i saw couple of drivers in panel-simple for this manufacturer - but non of them seems to work)

<MoeIcenowy> s3b0: did you properly apply DT overlay?
<MoeIcenowy> DT overlay needs to be applied on top of the kernel's DT
