0013 The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
0014 with Static RAM for content retention in command mode and also supports
0015 video mode with VESA Frame Buffer Compression or Display Stream Compression
0016 on single, or dual dsi port(s).
0017 This DDIC is also capable of upscaling an input image to the panel's native
0018 resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
0019 either bilinear interpolation or pixel duplication.

0031 that is in turn using the NT35950 panel driver. The compatible
0032 string determines how the NT35950 panel driver shall be configured
0033 to work with the indicated panel. The novatek,nt35950 compatible shall
0034 always be provided as a fallback.
