What's MIPI EXPAND?

[Kreyren]

The the board has the following:

• MIPI EXPAND - Unclear
• MIPI CSI 0 - MIPI Camera Serial Interface 0
• MIPI DSI - MIPI Display Serial Interface
• TP - Touch Panel

Where the product page says that it has 4-line MIPI DSI, but only with 15 pins -> 2-line MIPI DSI then?

The datasheet says:

So I assume that the 40pin MIPI EXPAND is 4-lane MIPI CSI-only and doesn't support DSI? or can you confirm that it's both CSI and DSI?

trying to find a 10"~13" display for the board that fits in a rugged tablet atm and MIPI EXPAND is not specification by MIPI Alliance afaik so wants to make sure before potentially breaking the board or the display by connecting a thing into a wrong connector

You can get schematic here: https://dl.sipeed.com/shareURL/LICHEE/licheepi4a/02_Schematic
The 26pin connector and the 40pin connector is for MIPI-CSI cameras only, but there is also a 31pin connector for MIPI-DSI screens.
