Integrate it with existing Novatek driver or at least consult its
maintainers what to do.

Novatek nt36672e and nt36672a differ in resolution, power on/off sequence (init sequence, delays), panel reset sequence.
NT36672E panel supports refresh rates of 60Hz, 90Hz, 120Hz and 144Hz. It also supports DSC.
To start with, I have added support for uncompressed 60Hz. In subsequent patches, other configurations
support will be added.
I have added Sumit Semwal, maintainer of nt36672a panel in cc. We feel it's better to have a new panel driver. Please let us know your thought.
Thanks,
Ritesh
