Hello everyone,

with the integration of custom bitwidth on DPI output in commit aafd4205a75de
("drm: mxsfb: Add optional DPI output bus-width configuration") the display
support for TQMa6UL[L]x on MBa6ULx can be added.
The mainboard uses a slightly different hardware connection which needs
customization.
Both LVDS and parallel display support is added resuing the DT overlays
for all the variants.

Thanks and best regards
Alexander

The generic setup like pinmux and lcdif <-> display connection is done
in the mainboard while LVDS specific setup is done in the overlay.
As this mainboard also supports parallel display the LVDS connection
using an LVDS encoder is done in the overlay.

Both displays are attached on X4 and differ only in display settings.
Note: Due to hardware wiring a 24-Bit bus-width has to be used.

Can you check if shared one overlay files with
ls1021a-tqmls1021a-mbls1021a-lvds-tm070jvhg33.dtso

I suppose use the model between two boards.

You use two labels like

reg_lvds: reg_mba6ul_3v3: regulator { ... } to create unified label naming
for regulator.

GPIO can use nexus node to do mapping.
