[media] V4L2: soc-camera: fix uninitialised use compiler warning

2013-06-28T17:57:18+00:00

In scan_async_group() if the size parameter is negative, the sasd pointer will be used uninitialised: drivers/media/platform/soc_camera/soc_camera.c: In function "soc_camera_host_register": drivers/media/platform/soc_camera/soc_camera.c:1514:55: warning: "sasd" may be used uninitialized in this function [-Wmaybe-uninitialized] sasd->asd.match.i2c.adapter_id, sasd->asd.match.i2c.address); ^ drivers/media/platform/soc_camera/soc_camera.c:1464:34: note: "sasd" was declared here struct soc_camera_async_subdev *sasd; Fix this by making "size" and the array, from which it is assigned unsigned.

[media] sh_mobile_ceu_camera: add asynchronous subdevice probing support

2013-06-21T19:35:53+00:00

Use the v4l2-async API to support asynchronous subdevice probing, including the CSI2 subdevice. Synchronous probing is still supported too. Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] V4L2: sh_mobile_ceu: manage lower 8bit bus

[media] V4L: sh_mobile_ceu_camera: maximum image size depends on the hardware version

2012-03-20T01:11:06+00:00

Newer CEU versions, e.g., the one, used on sh7372, support image sizes larger than 2560x1920. Retrieve maximum sizes from platform properties. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L: sh_mobile_csi2: switch away from using the soc-camera bus notifier

2011-07-27T20:56:08+00:00

This moves us one more step closer to eliminating the soc-camera bus and devices on it. Besides, as a side effect, CSI-2 runtime PM on sh-mobile secomes finer grained now: we only have to power on the interface, when the device nodes are open.

V4L/DVB: V4L2: sh_mobile_camera_ceu: add support for CSI2

2010-08-02T19:43:40+00:00

Using CEU with CSI2 on SH-Mobile requires some special configuration of the former. We also have to switch from calling only one subdev .s_mbus_fmt and .try_mbus_fmt to calling all subdevices. Take care to increment CSI2 driver use count to prevent it from unloading, while in use. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (8687): soc-camera: Move .power and .reset from soc_camera host to sensor driver

2008-10-12T11:36:50+00:00

Make .power and .reset callbacks per camera instead of per host, also move their invocation to camera drivers. .arch/arm/mach-pxa/include/mach/camera.h | 2 - Signed-off-by: Stefan Herbrechtsmeier Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (8342): sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3

2008-07-20T10:25:43+00:00

This is V3 of the SuperH Mobile CEU soc_camera driver. The CEU hardware block is configured in a transparent data fetch mode, frames are captured from the attached camera and written to physically contiguous memory buffers provided by the newly added videobuf-dma-contig queue. Tested on sh7722 and sh7723 processors. Changes since V2: - remove SUPERH Kconfig dependency - move sh_mobile_ceu.h to include/media - add board callback support with enable_camera()/disable_camera() - add support for declare_coherent_memory - rework video memory limit - more verbose error messages Changes since V1: - fixed the CEU driver to work with the newly updated patches Signed-off-by: Magnus Damm Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab
