CSI-2 (CSI4LNK0) on R-Car and RZ/G2 supports 4-lane mode which is already handled by rcar-csi2.c driver. This patch updates the data-lanes property to describe the same. Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> --- Hi All, Instead of adding uniqueItems:true into SoC binding doc's I think we could add this in video-interfaces.yaml for data-lanes property. Any thoughts on this? Cheers, Prabhakar v1->v2 * Dropped const items * Added uniqueItems v1: https://lore.kernel.org/lkml/20220118163413.ge2b4g75yhfqvq3x@uno.localdomain/T/ --- Documentation/devicetree/bindings/media/renesas,csi2.yaml | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-)
