I have now tested v3 on Ebisu E3 which has only 2 data lanes connected.

Hi, This series allows the TXA CSI-2 transmitter of the adv748x to function in 1-, 2- and 4- lane mode. Currently the driver fixes the hardware in 4-lane mode. The driver looks at the standard DT property 'data-lanes' to determine which mode it should operate in. Patch 1/4 lists the 'data-lanes' DT property as mandatory for endpoints describing the CSI-2 transmitters. Patch 2/4 refactors the initialization sequence of the adv748x to be able to reuse more code. Patch 3/4 adds the DT parsing and storing of the number of lanes. Patch 4/4 merges the TXA and TXB power up/down procedure while also taking the configurable number of lanes into account. The series is based on the latest media-tree master and is tested on Renesas M3-N in 1-, 2- and 4- lane mode.
