DS90UB981-Q1: dual channel DSI

Part Number: DS90UB981-Q1

HI, TI

The DS90UB981-Q1 support dual-channel DSI (2clk+8lane) input ?

The datasheet only 4 lanes.

1. If support dual-channel DSI (2clk+8lanes) input, how to set the registers?
2. What are the recommended DSI (lanes number) settings when 3840x1080@30fps?

Thanks.
