The model and make of the LCD panel of the Vivax TPC-9150 is unknown,
hence the panel settings that were retrieved with a FEX dump are named
after the device NOT the actual panel.

The LCD in question is a 50 pin MISO TFT LCD panel of the resolution
1024x600 used by the aforementioned device.

Version 2, as Thierry kindly suggested that I fix the order in which the
panel was ordered compared to others.

Version 3, filling in the required info suggested by Sam. Plus some
factual issues that I've corrected myself (tested working)

Version 4, rearranged the display parameters and fix invalid bit format
issue. (Thanks Sam)

Thanks,
Nikola

This tablet display is unique and hence must be added to documentation.
Unfortunately, it's real make and number is not known due to obscure and
missing documentation and lack of writing on the display assembly
itself.

So the natural alternative that came to mind is to name the panel after
the device that contained it (an Android tablet). Hopefully that isn't
an issue.

I can confirm that the parameters that I've obtained are correct since
they came from a dump of the original Android OS.
