media: imx-mipi-csis: Support active data lanes differing from maximum

2025-11-13T09:57:52Z

Call on v4l2_get_active_data_lanes() to check if the driver reports that the number of lanes actively used by the MIPI CSI transmitter differs to the maximum defined in device tree. If the number of active data lanes reported by the driver is invalid, catch and return the error. If the operation is not supported, fall back to the number of allowed data lanes.

media: imx-mipi-csis: Add num_data_lanes to mipi_csis_device

2025-11-13T09:57:52Z

Add the num_data_lanes field to the mipi_csis_device struct, and set it equal to csis->bus.num_data_lanes. This is in preparation to support cases when the data lanes actively used differs from the maximum supported data lanes. No functional changes intended by this commit.

media: imx-mipi-csis: Move redundant debug print in probe

2025-11-13T09:57:52Z

The number of data lanes is already printed as part of mipi_csis_async_register(), making the first part of this print redundant. Remove the redundant print, and move the debug print for clock frequency to mipi_csis_parse_dt().

2025-11-03T10:40:22Z

The ISI module on i.MX91 implements only one channel and one parallel camera input. As no input source selection is required, gasket ops are unnecessary.
