And the module itself have the compatible string of "newvision,nv3051d"? My fear is that I write this as a newvision,nv3051d kernel module and then later on there comes a new panel using the nv3051d that wants to use this too. Again keeping things confusing I have no LCD panel part number from the manufacturer for this, and I cannot see anything on the panel itself denoting what LCD it is. Thank you for your help. Just wrapping up getting some of my favorite devices supported in mainline. :-)
