12description: |
13  ST7701 designed for small and medium sizes of TFT LCD display, is
14  capable of supporting up to 480RGBX864 in resolution. It provides
15  several system interfaces like MIPI/RGB/SPI.
16
17  Techstar TS8550B is 480x854, 2-lane MIPI DSI LCD panel which has
18  inbuilt ST7701 chip.
19
20  Densitron DMT028VGHMCMI-1A is 480x640, 2-lane MIPI DSI LCD panel
21  which has built-in ST7701 chip.
