2016-09-19[media] media: rcar-vin: add support for V4L2_FIELD_ALTERNATENiklas Söderlund
The HW can capture both ODD and EVEN fields in separate buffers so it's possible to support V4L2_FIELD_ALTERNATE. This patch add support for this mode. At probe time and when S_STD is called the driver will default to use V4L2_FIELD_INTERLACED if the subdevice reports V4L2_FIELD_ALTERNATE. The driver will only change the field type if the subdevice implements G_STD, if not it will keep the default at V4L2_FIELD_ALTERNATE. The user can always explicitly ask for V4L2_FIELD_ALTERNATE in S_FMT and the driver will use that field format.

2016-09-19[media] media: rcar-vin: fix height for TOP and BOTTOM fieldsNiklas Söderlund
The height used for V4L2_FIELD_TOP and V4L2_FIELD_BOTTOM where wrong. The frames only contain one field so the height should be half of the frame.

2016-09-19[media] media: rcar-vin: fix bug in scalingNiklas Söderlund
It was not possible to scale beyond the image size of the video source limitation. The output frame would be bigger but the captured image was limited to the size of the video source. The error was that the crop boundary was set after the requested frame size and not the video source size. This patch breaks out the resetting of the crop, compose and format to separate functions so the error wont creep back.

2016-09-19[media] media: rcar-vin: allow field to be changedNiklas Söderlund
The driver forced whatever field was set by the source subdevice to be used. This patch allows the user to change from the default field.

2016-08-24[media] v4l2-subdev: rename cropcap to g_pixelaspectHans Verkuil
The old cropcap video op is now only used to pass the pixelaspect ratio, so rename it. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-23[media] rcar-vin: move media bus information to struct rvin_graph_entityNiklas Söderlund
The primary reason for this change is to prepare for Gen3 support where there will be more then one possible video source. Each source will have its own media bus format and code, so it needs to be moved from the per device structure to a structure used to represent an individual connection to a video source.

2016-08-23[media] rcar-vin: do not use v4l2_device_call_until_err()Niklas Söderlund
Fix a error from the original driver where v4l2_device_call_until_err() where used for the pad specific v4l2 operation set_fmt. Also fix up the error path from this fix so if there is an error it will be propagated to the caller. The error path label have also been renamed as a result from a nitpicking review comment since we are fixing other issues here.

2016-06-28[media] media: rcar-vin: pad-aware driver initialisationUlrich Hecht
Add detection of source pad number for drivers aware of the media controller API, so that rcar-vin can create device nodes to support modern drivers such as adv7604.c (for HDMI on Lager) and the converted adv7180.c (for composite) underneath. Building rcar_vin gains a dependency on CONFIG_MEDIA_CONTROLLER, in line with requirements for building the drivers associated with it.
