| 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. |

| 32 | string determines how the NT35950 panel driver shall be configured |
| 33 | to work with the indicated panel. The novatek,nt35950 compatible shall |
| 34 | always be provided as a fallback. |
