[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This driver has been replaced by the non-soc-camera rcar-vin driver.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: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct vb2_ops i@p = { ... }; @ok@ identifier r.i; struct vb2_queue e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct vb2_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct vb2_ops i = { ... }; // Signed-off-by: Julia Lawall Reviewed-by: Laurent Pinchart Reviewed-by: Fabien Dessenne Reviewed-by: Jacek Anaszewski Reviewed-by: Benoit Parrot [hans.verkuil@cisco.com: dropped soc_camera/rcar_vin.c patch because that driver will be removed] Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: platform: pxa_camera: move pxa_camera out of soc_camera

2016-09-09T13:54:11+00:00

As the conversion to a v4l2 standalone device is finished, move pxa_camera one directory up and finish severing any dependency to soc_camera. Signed-off-by: Robert Jarzmik Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Robert Jarzmik Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: platform: pxa_camera: add debug register access

2016-09-09T13:52:56+00:00

[media] media: platform: pxa_camera: make a standalone v4l2 device

2016-09-09T13:52:31+00:00

This patch removes the soc_camera API dependency from pxa_camera. In the current status : - all previously captures are working the same on pxa270 - the s_crop() call was removed, judged not working (see what happens soc_camera_s_crop() when get_crop() == NULL) - if the pixel clock is provided by then sensor, ie. not MCLK, the dual stage change is not handled yet. => there is no in-tree user of this, so I'll let it that way - the MCLK is not yet finished, it's as in the legacy way, ie. activated at video device opening and closed at video device closing. In a subsequence patch pxa_camera_mclk_ops should be used, and platform data MCLK ignored. It will be the sensor's duty to request the clock and enable it, which will end in pxa_camera_mclk_ops.

[media] media: platform: pxa_camera: remove set_selection

2016-09-09T13:50:38+00:00

This is to be seen as a regression as the set_selection (former set_crop) function is removed. This is a temporary situation in the v4l2 porting, and will have to be added later. Signed-off-by: Robert Jarzmik Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: platform: pxa_camera: add buffer sequencing

[media] media: platform: pxa_camera: make printk consistent

2016-09-09T13:46:10+00:00

Make all print consistent by always using : - dev_xxx(pcdev_to_dev(pcdev), ....) This prepares the soc_camera adherence removal by making these call rely on only pcdev, and not the soc_camera icd structure.

[media] media: platform: pxa_camera: introduce sensor_call

2016-09-09T13:45:16+00:00

Introduce sensor_call(), which will be used for all sensor invocations. This is a preparation move to v4l2 device conversion, ie. soc_camera adherence removal. Signed-off-by: Robert Jarzmik Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
