So here we have the LCD timings in the device tree, which differs from
the the devicetree in mainline.

This is based on the old mxsfb fbdev driver, which has been removed in 5.3-rc.

In mainline we pass the innolux,at043tn24 LCD compatible.

Shouldn't U-Boot be able to handle the same dt-bindings as in the kernel?
