HORZ is nowhere used. HOR is more commonly used in control names.
V4L2_CID_MPEG_VIDEO_MV_H_SEARCH_RANGE seems better.

It's expressed in pixels? If so then it should be mentioned here. Also I
think this lacks the mention that it is used for motion estimation.
Please add a more detailed description.

This description is too vague as well.

These two controls sound very mfc specific as opposed to being part of the standard.
If so, then they should be named V4L2_CID_MPEG_MFC51_*. Also, for which codecs are
these controls applicable?

Don't set the name here if the control is also defined in v4l2-ctrls.
That way the string from v4l2-ctrls is the leading definition.

mencoder has an option to set motion vector search radius.

>From man mencoder:
me_range=<4-64>
radius of exhaustive or multi-hexagon motion search
(default:
16)

So I think it could be applicable to other hardware codecs as well.

> Also, for which codecs are these controls applicable?

Isn't the choice of motion estimation algorithm (and its parameters)
codec agnostic, as long as the restrictions of the standard are honoured?

If the search range is represented in pixels, then pixels should be used.
It the control is also used in other hardware, then I think it the values
should not be limited in this way here. For example mencoder accepts the
value between 4 and 64. The range and step could be limited in the
s5p_mfc_enc.c.

This is v3 version for the patch:
s5p-mfc: Add Horizontal and Vertical search range for Video Macro Blocks
(https://lkml.org/lkml/2013/12/30/83)

Changes from v1:
1) Splitted the patch into V4L2 and MFC driver patches.
2) Incorporated review comments on v1.

Changes from v2:
1) Removed the range restrictions from drivers/media/v4l2-core/v4l2-ctrls.c.
2) Rebased the patch to git://linuxtv.org/mchehab/media-next.git.
3) Added [media] tag in title.
