The SoC's used on the Raspberry Pi range all have two camera interfaces that support either CSI-2 D-PHY 1.1 or CCP2 (Compact Camera Port 2) sources. This interface is known by the codename "Unicam". The first instance of Unicam supports 2 CSI-2 data lanes, whilst the second supports 4. Each lane can run at up to 1Gbit/s (DDR, so the max link frequency is 500MHz).
Overclocking may get you slightly beyond that, but 1Gbit/s/lane is the design spec.
