+
+The WAVESHARE DSI LCD Panel Shield is a universal driver shield.
+The shield can be used to drive various DSI LCD panel.
+
+More information about the shield can be found
+-at the `WAVESHARE DSI LCD Panel website`_.

+
+Requirements
+************
+
+This shield can only be used with a board that provides a configuration
+for MIPI DSI and defines node aliases for I2C interfaces
+(see :ref:`shields` for more details).
+
+Programming
+***********
+
+Correct shield designation (see the table above) for your display must
+be entered when you invoke ``west build``.
+For example:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/subsys/display/lvgl
+   :board: frdm_imx93/mimx9352/a55
+   :shield: waveshare_7inch_dsi_lcd_c
+   :goals: build
