our device is based on the efusA9X-V8-W13 with display EDT ET0430G8DH6 (or ET0430G0DH6 on some older boards). Until now there was WinCE OS and the display works correctly with it using the driver (ET043080).
Now I am creating a Linux using the fsimx6sx-B2019.11 and I am unable to activate the display connected to our device. I tried to modify the efusa9x.dts in the linux-4.9.88 sources, but with no success. By default it contains settings for a WVGA display (800x480), but our display (mentioned above) has WQVGA resolution: 480x272.
Do you have a hint how to modify the DTS to support the display? Or is it a driver issue?
