some clue what bus_format and bus_flags I have to use?

the first two errors are gone. But I still get this:
[ 42.387107] mxsfb 21c8000.lcdif: Cannot connect bridge: -517
The panel is still off perhaps I miss something else.

Some suggestions:
- Take a look at arch/arm/boot/dts/imx6ul-14x14-evk.dtsi as a reference as it has display functional - Use imx_v6_v7_defconfig to make sure all the required drivers are selected - If it still does not work, share the dts and schematics

ok I checked imx6ul-14x14-evk.dtsi and use imx_v6_v7_defconfig
- If it still does not work, share the dts and schematics
here the schematics and my dts. The board is using a LVDS connector for the display.

The schematics shows the GKTW70SDAD1SD panel in the J4 connector, not the LVDS J7 connector.

As I mentioned earlier you should remove the display timings from the dts when using the compatible string for the panel.
power-supply = <®_touch_3v3> is not correct, as the reg_touch_3v3 does not power the LCD.
Another hint is to use the PLL5_VIDEO as the clock source for the lcdif controller as done in the imx6ul evk dtsi.
It would also help if you could share the complete boot log.

yes you are right. But how to I map this fact correctly in my dts?

I got this and removed the display timings.
power-supply = <®_touch_3v3> is not correct, as the reg_touch_3v3 does not power the LCD.
yes, but how is the LCD correctly powered then?

I already figured it out and tried it. But because of the faults above it didn't make any difference.
It would also help if you could share the complete boot log.
here is the boot log

power-supply = <®_touch_3v3> is not correct, as the reg_touch_3v3 does not power the LCD.
yes, but how is the LCD correctly powered then?
J4 is powered by VCC_5V and VCC_3V#.

Ok I fixed the pin conflict with regulator-gpio and added a 5V regulator node in my dts file. Now the display is working fine!
I'll post the dts files soon and check if there is something to improve for this patch.
Many thanks for your help,
Oliver

That's good news :-)

Did the panel patch I sent earlier work? https://pastebin.com/raw/diTMVsh8
If it does, I can send it formally if you want.

I would prefer mine, because I got a wrong colored penguin on bootup with yours :-)

I have originally passed .bpc = 8, but looking at the panel datasheet, this should be: .bpc = 6 instead.
In your patch, you pass the timing parameters three times, but they are all the same.
Usually, it is meant to be: minimal, typical, maximum values.

The wrong colored Tux is caused by the bus_format:
.bus_format = MEDIA_BUS_FMT_RGB888_1X24,
So I assume I need another bus_format here.

yes this is right. I found it too in the datasheet. I'll fix it in next version of the patch.

yes because on a lot of entries there is just the typical value and no min and max. But not on all of them.

Oliver

the first two errors are gone. But I still get this:
[ 42.387107] mxsfb 21c8000.lcdif: Cannot connect bridge: -517
The panel is still off perhaps I miss something else.
Some suggestions:
- Take a look at arch/arm/boot/dts/imx6ul-14x14-evk.dtsi as a
reference as it has display functional
- Use imx_v6_v7_defconfig to make sure all the required drivers are selected
ok I checked imx6ul-14x14-evk.dtsi and use imx_v6_v7_defconfig
- If it still does not work, share the dts and schematics
here the schematics and my dts. The board is using a LVDS connector for the display.

The DT6CustomBoard uses almost the same screen (sgd,gktw70sdae4se), it's supported and tested in kernelci, you can find the dt in arch/arm/boot/dts/imx6q-var-dt6customboard.dts
