| 12 | description: | |
| 13 | This is a driver for 320x240 TFT panels, accepting a variety of input |
| 14 | streams that get adapted and scaled to the panel. The panel output has |
| 15 | 960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and |
| 16 | VCOMH outputs. |
| 17 | |
| 18 | The panel must obey the rules for a SPI slave device as specified in |
| 19 | spi/spi-controller.yaml |
