and capacitive touch screen.
.. note::
Currently only the older version MB1166-A03 is supported by Zephyr.
The newer version MB1166-A09 does not get initialized correctly (see :github:`60888`).
The shield comes in different hardware revisions, the MB1166-A09
is utilizing a NT35510 panel controller and shall specifically
use ``st_b_lcd40_dsi1_mb1166_a09`` as SHIELD when building
Prior versions are utilizing an OTM8009a controller and shall
use shield name without postfix, that is: ``st_b_lcd40_dsi1_mb1166``

The shield can be used in any application by setting ``SHIELD`` to
``st_b_lcd40_dsi1_mb1166`` and adding the necessary device tree properties.
``st_b_lcd40_dsi1_mb1166`` or ``st_b_lcd40_dsi1_mb1166_a09`` and adding
