Instead, in the MEI CSI driver, just obtain the link frequency from the upsteam sub-device and pass it on to the receiver. The v4l2_get_link_freq() is changed to add support for this and it's documented as well. Sakari Ailus (3): media: v4l: Support obtaining link frequency from INTEGER64 controls media: Documentation: v4l: LINK_FREQ can be an INTEGER64 control media: ivsc: csi: Fix link frequency control behaviour .../media/v4l/ext-ctrls-image-process.rst | 2 +- drivers/media/pci/intel/ivsc/mei_csi.c | 30 +++++++++---------- drivers/media/v4l2-core/v4l2-common.c | 3 ++ 3 files changed, 18 insertions(+), 17 deletions(-)
