[media] v4l2-subdev: remove enum_framesizes/intervals

2015-03-23T19:02:41Z

The video and pad ops are duplicates, so get rid of the more limited video op. The whole point of the subdev API is to allow reuse of subdev drivers by bridge drivers. Having duplicate ops makes that much harder. We should never have allowed duplicate ops in the first place. A lesson for the future.

[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config

2015-03-23T18:41:36Z

If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

[media] v4l2-subdev: drop unused op enum_mbus_fmt

Weird, this op isn't used at all. Seems to be orphaned code. Remove it. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-subdev: drop get/set_crop pad ops

2014-12-22T20:12:36Z

Drop the duplicate get/set_crop pad ops and only use get/set_selection. It makes no sense to have two duplicate ops in the internal subdev API. Signed-off-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: subdev: Remove deprecated video-level DV timings operations

The video enum_dv_timings and dv_timings_cap operations are deprecated and unused. Remove them. Signed-off-by: Laurent Pinchart Reviewed-by: Hans Verkuil Acked-by: Sakari Ailus Acked-by: Lad, Prabhakar Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Add pad-level DV timings subdev operations

2014-05-25T15:37:57Z

The dv_timings_cap and enum_dv_timings subdev operations are implemented at the device level, but apply to pads. Create new variants of those operations at the pad level. The device level variants will be removed once all drivers are ported to the pad level DT timings operations.

[media] v4l2-subdev.h: add g_tvnorms video op

2014-05-13T22:55:20Z

While there was already a g_tvnorms_output video op, it's counterpart for video capture was missing. Add it. This is necessary for generic bridge drivers like soc-camera to set the video_device tvnorms field correctly. Otherwise ENUMSTD cannot work.

V4L2_MBUS_FRAME_DESC_FL_BLOB intends to say the receiver must use 1D DMA to receive the image, as the format does not have line offsets. This typically includes all compressed formats. Signed-off-by: Sakari Ailus Cc: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab
