| 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. |

| 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. |
