Hi folks,

This set adds a few helpers for obtaining the link frequency from the V4L2
mbus config for devices that don't need to provide an UAPI to change it,
and finally add support for the Intel IVSC CSI device.

since v2:

- Switch to V4L2 mbus config for conveying the link frequency.

since v1:

- Add a new 64-bit integer control V4L2_CID_CUR_LINK_FREQ instead of
  re-using V4L2_CID_LINK_FREQ.

Sakari Ailus (4):
  media: v4l: Support passing sub-device argument to
    v4l2_get_link_freq()
  media: v4l: Support obtaining link frequency via get_mbus_config
  media: Documentation: Update link frequency driver documentation
  media: ivsc: csi: Obtain link frequency from the media pad
