+description: |+
+  This DSI panel contains:
+
+  - TC358762 DSI->DPI bridge
+  - Atmel microcontroller on I2C for power sequencing the DSI bridge and
+    controlling backlight
+  - Touchscreen controller on I2C for touch input
+
+  and this binding covers the DSI display parts but not its touch input.
