v4l: async: Add a pointer to of_node to struct v4l2_subdev, match it

2015-06-15T18:37:05+00:00

V4L2 async sub-devices are currently matched (OF case) based on the struct
device_node pointer in struct device. LED devices may have more than one
LED, and in that case the OF node to match is not directly the device's
node, but a LED's node.

[media] v4l2-subdev: allow subdev to send an event to the v4l2_device notify function

2015-05-20T16:40:02+00:00

All drivers use custom notifications, in particular when source changes.
The bridge only has to map the subdev that sends it to whatever video node it is connected to.

[media] v4l2: replace s_mbus_fmt by set_fmt in bridge drivers

2015-05-01T12:01:16+00:00

Replace all calls to s_mbus_fmt in bridge drivers by calls to the
set_fmt pad op.

Remove the old try/s_mbus_fmt video ops since they are now no longer used.

[media] v4l2: replace video op g_mbus_fmt by pad op get_fmt

2015-05-01T11:36:17+00:00

The g_mbus_fmt video op is a duplicate of the pad op. Replace all uses
by the get_fmt pad op and remove the video op.

[media] v4l2-subdev: remove enum_framesizes/intervals

2015-03-23T19:02:41+00:00

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

2015-03-23T18:41:36+00:00

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 get/set_crop pad ops

2014-12-22T20:12:36+00:00

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.
