description: |
  The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
  with Static RAM for content retention in command mode and also supports
  video mode with VESA Frame Buffer Compression or Display Stream Compression
  on single, or dual dsi port(s).
  This DDIC is also capable of upscaling an input image to the panel's native
  resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
  either bilinear interpolation or pixel duplication.

      to work with the indicated panel. The novatek,nt35950 compatible shall
      always be provided as a fallback.
