Some MIPI CSI-2 transmitters, such as TC358743 can dynamically change the number of active data lanes depending on the bandwidth needs for the selected video format. This patchset adds a subdevice video operation g_csi_active_lanes() to let the MIPI CSI-2 receiver query the number of active lanes and change its configuration accordingly. Changes since v3 [1]: - Add g_csi_active_lanes() subdevice video operation, implement it in tc358743, and use it in imx6-mipi-csi2.
