3eef25107c [media] v4l2: drop V4L2_CHIP_MATCH_SUBDEV_NAME
After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.

79b0c64005 [media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl
Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.

9d5f4839cc [media] v4l2-common: remove obsolete check for ' at the end of a driver name
During the transition to sub-devices several years ago non-subdev drivers
had a ' at the end of their driver name to tell them apart from already
converted drivers. This check was a left-over from that time and can be
removed.

abd2329564 [media] v4l: Helper function for obtaining timestamps
v4l2_get_timestamp() produces a monotonic timestamp but unlike
ktime_get_ts(), it uses struct timeval instead of struct timespec, saving
the drivers the conversion job when getting timestamps for v4l2_buffer's
timestamp field.

c61bd6a0e2 [media] v4l2-common: add CVT and GTF detection functions
These two helper functions detect whether the analog video timings detected
by the video receiver match the VESA CVT or GTF standards.

They basically do the inverse of the CVT and GTF modeline calculations.

This patch also adds a helper function that will determine the aspect ratio
based on the provided EDID values. This aspect ratio can be given to the GTF
helper function.
