[media] soc-camera: fix rectangle adjustment in cropping

2017-03-23T17:45:59+00:00

update_subrect() adjusts the sub-rectangle to be inside a base area.
It checks width and height to not exceed those of the area, then it
checks the low border (left or top) to lie within the area, then the
high border (right or bottom) to lie there too. This latter check has
a bug, which is fixed by this patch.

[media] media: platform: soc_camera_platform : constify v4l2_subdev_* structures

2017-01-30T16:47:21+00:00

v4l2_subdev_{core/video}_ops structures are stored in the
fields of the v4l2_subdev_ops structure which are of type const.
Also, v4l2_subdev_ops structure is passed to a function
having its argument of type const. As these structures are never
modified, so declare them as const.
Done using Coccinelle:(One of the scripts)

[media] soc-camera/rcar-vin: remove obsolete driver

2016-09-19T19:29:54+00:00

This driver has been replaced by the non-soc-camera rcar-vin driver.
The soc-camera framework is being deprecated, so drop this older
rcar-vin driver in favor of the newer version that does not rely on
this deprecated framework.

[media] platform: constify vb2_ops structures

2016-09-19T19:21:06+00:00

Check for vb2_ops structures that are only stored in the ops field of a
vb2_queue structure.  That field is declared const, so vb2_ops structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:

static struct vb2_ops i@p = { ... };

[media] media: platform: pxa_camera: change stop_streaming semantics

2016-09-09T13:53:31+00:00

Instead of the legacy behavior where it was required to wait for all
video buffers to be finished by the hardware, use a cancel like strategy
: as soon as the stop_streaming() call is done, abort all DMA transfers,
report the already buffers as failed and return.

This makes stop_streaming() more a "cancel capture" than a "wait for end
of capture" semantic.
