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.

description: This indicates the panel manufacturer of the panel
that is in turn using the NT35950 panel driver. The compatible
string determines how the NT35950 panel driver shall be configured
to work with the indicated panel. The novatek,nt35950 compatible shall
always be provided as a fallback.
