MachXO2: RD1146 states that the LP pins need to be HSTL18, the DPHY reference document RD1182 also says the LP pins should be 1.2V. Which one is correct?

Description:
MIPI CSI2 RX interface RD1146 was the first to be introduced and the termination scheme used for that was using HSTL18 for the LP signals.

The D-Phy(RD1182) was introduced later and the termination scheme optimized and superseded the termination scheme and IO Standard for the LP signals. Both work and you could use either of the two.
