Setup number of data lanes for the CSI ports.
00/01: 4 data lanes
10: 2 data lanes
0
When set, put the data lanes in ultra-low power mode (LP00) by
sending out a LP signalling sequence.
0
When set with ULPM, put the clock lane into ultra-low power
mode. No effect if ULPM is not set.
0
When set, keep the clock lane running (in HS mode) during line
blank (DE=0) and frame black (VS not active)
0
When set, disable the CSI state machine. Function as a soft
reset.

0
When set, the VS received from the digital receiver will be
inverted. Because the CSI logic works on active-high VS, this
bit is typically set when the VS from the data source is active-
low.
0
When set, the DE received from the digital receiver will be
inverted. Because the CSI logive works on active-high DE, this
bit is typically set when the DE from the data source is active-
low.
