Your board needs to have a mipi_dsi device tree label to work with this shield.

The shield can be used in any application by setting SHIELD to st_b_lcd40_dsi1_mb1166 and adding the necessary device tree properties.

Set -DSHIELD="st_b_lcd40_dsi1_mb1166" when you invoke west build. For example:

# From the root of the zephyr repository
west build -b stm32h747i_disco_m7 samples/drivers/display -- -DSHIELD=st_b_lcd40_dsi1_mb1166
