I don't mean we should do that.

What I mean is:

- Name the driver after the controller, if we know which one it is,
  such as panel-novatek-nt35510.c

- Provide identifications of the controller+panel combo in e.g.
  DT compatible strings, provide init data as arrays in the per-variant
  match data (or similar for ACPI).
