 12description: |
 13  The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
 14  with Static RAM for content retention in command mode and also supports
 15  video mode with VESA Frame Buffer Compression or Display Stream Compression
 16  on single, or dual dsi port(s).
 17  This DDIC is also capable of upscaling an input image to the panel's native
 18  resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
 19  either bilinear interpolation or pixel duplication.

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