description: |
  ST7701 designed for small and medium sizes of TFT LCD display, is
  capable of supporting up to 480RGBX864 in resolution. It provides
  several system interfaces like MIPI/RGB/SPI.

  Techstar TS8550B is 480x854, 2-lane MIPI DSI LCD panel which has
  inbuilt ST7701 chip.

  Densitron DMT028VGHMCMI-1A is 480x640, 2-lane MIPI DSI LCD panel
  which has built-in ST7701 chip.
