+title: NewVision NV3052C TFT LCD panel driver with SPI control bus
+
+maintainers:
+  - Paul Cercueil <paul@...pouillou.net>
+
+description: |
+  This is a driver for 320x240 TFT panels, accepting a variety of input
+  streams that get adapted and scaled to the panel. The panel output has
+  960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
+  VCOMH outputs.
+
+  The panel must obey the rules for a SPI slave device as specified in
+  spi/spi-controller.yaml
