Okay, will do that. This is a tricky one because while I know the panel controller IC (a NewVision NV3051D) I don't actually know the LCD panel itself, the vendor is somewhat tight lipped. I do know the product it goes into, so that's why I did what I did with the compatible strings. If that's not correct I guess let me know.

If by "driver" you mean by "Linux driver", then it does not really matter. You describe here the hardware. The example of NV3052C follows this approach - proper compatible and file name matching hardware.

The underlying panel part number for the RG353x devices is unknown, so the device name is used instead.
