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.

Specifying .connector_type is mandatory today. Please specify .bpc too.
Consider if .bus_flags cover it all, they can be a little tricky to add them all. And many many displays have failed to do so.
I hope to see a new version soon with these comments and also the comments from Thierry fixed.
