doc-rst: Remove the media docbook

2016-07-28T23:08:19Z

Now that all media documentation was converted to Sphinx, we should get rid of the old DocBook one, as we don't want people to submit patches against the old stuff. Signed-off-by: Mauro Carvalho Chehab Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] DocBook/media: clarify control documentation

2015-10-01T11:31:57Z

- Add missing V4L2_CTRL_TYPE_U32 documentation - Remove 'which are actually different on the hardware' sentence which is confusing. I think the idea was to let the user know that the step can be different for different hardware, but that's obvious because otherwise you wouldn't need to specify the step value. - Clarify that V4L2_CTRL_COMPOUND_TYPES also applies to arrays.

[media] DocBook media typo

2014-07-22T03:43:08Z

V4L2_CID_BASE_LASTP1 should be V4L2_CID_LASTP1. This has probably been wrong since the earliest days of this documentation until I did a copy-and-paste and found out that V4L2_CID_BASE_LASTP1 doesn't actually exist :-) Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: use __u32 rather than enums in ioctl() structs

2012-05-14T11:09:02Z

V4L2 uses the enum type in IOCTL arguments in IOCTLs that were defined until the use of enum was considered less than ideal. Recently Rémi Denis-Courmont brought up the issue by proposing a patch to convert the enums to unsigned: This sparked a long discussion where another solution to the issue was proposed: two sets of IOCTL structures, one with __u32 and the other with enums, and conversion code between the two: Both approaches implement a complete solution that resolves the problem. The first one is simple but requires assuming enums and __u32 are the same in size (so we won't break the ABI) while the second one is more complex and less clean but does not require making that assumption. The issue boils down to whether enums are fundamentally different from __u32 or not, and can the former be substituted by the latter. During the discussion it was concluded that the __u32 has the same size as enums on all archs Linux is supported: it has not been shown that replacing those enums in IOCTL arguments would break neither source or binary compatibility. If no such reason is found, just replacing the enums with __u32s is the way to go. This is what this patch does. This patch is slightly different from Remi's first RFC (link above): it uses __u32 instead of unsigned and also changes the arguments of VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY.
