2017-10-31media: rcar-vin: Use generic parser for parsing fwnode endpointsSakari Ailus1-7/+7
Instead of using a custom driver implementation, use v4l2_async_notifier_parse_fwnode_endpoints() to parse the fwnode endpoints of the device.

2017-06-06[media] rcar-vin: move pad lookup to async bound handlerNiklas Söderlund1-22/+0
Information about pads will be needed when enumerating the media bus codes in the async complete handler which is run before rvin_v4l2_probe().

2017-06-06[media] rcar-vin: move subdev source and sink pad index to rvin_graph_entityNiklas Söderlund1-10/+10
It makes more sense to store the sink and source pads in struct rvin_graph_entity since that contains other subdevice related information. The data type to store pad information in is unsigned int and not int, change this. While we are at it drop the _idx suffix from the names, this never made sense.

The driver supports a single input only, which can be either analog or digital. If the subdevice supports dv_timings_cap the input is digital and the driver should not fill in the standard.

2017-06-06[media] rcar-vin: fix how pads are handled for v4l2 subdevice operationsNiklas Söderlund1-12/+14
The rcar-vin driver only uses one pad, pad number 0. - All v4l2 operations that did not check that the requested operation was for pad 0 have been updated with a check to enforce this. - All v4l2 operations that stored (and later restored) the requested pad before substituting it for the subdevice pad number have been updated to not store the incoming pad and simply restore it to 0 after the subdevice operation is complete.

2016-09-19[media] media: rcar-vin: add support for V4L2_FIELD_ALTERNATENiklas Söderlund1-0/+13
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 bug in scalingNiklas Söderlund1-51/+54
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.

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.
