[media] V4L2: soc-camera: remove several CEU references in the generic scaler

2013-06-28T18:03:38Z

The scaling / cropping library, that has been extracted from the CEU driver still contained a couple of references to the original hardware. Clean them up. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L2: soc-camera: move generic functions into a separate file

2013-06-28T18:03:16Z

The sh_mobile_ceu_camera driver implements a generic algorithm for setting up an optimal client and host scaling and cropping configuration. This patch makes those functions available for all drivers. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L2: sh_mobile_ceu_camera: remove CEU specific data from generic functions

2013-06-28T18:01:58Z

Several functions in the sh_mobile_ceu_camera driver implement generic algorithms and can be re-used by other V4L2 camera host drivers too. These functions attempt to optimise scaling and cropping functions of the subdevice, e.g. a camera sensor. This patch makes those functions generic for future re-use by other camera host drivers.

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

2013-06-28T17:57:18Z

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

2013-06-21T19:35:53Z

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] soc-camera: add V4L2-async support

2013-06-21T19:34:17Z

Add support for asynchronous subdevice probing, using the v4l2-async API. The legacy synchronous mode is still supported too, which allows to gradually update drivers and platforms. The selected approach adds a notifier for each struct soc_camera_device instance, i.e. for each video device node, even when there are multiple such instances registered with a single soc-camera host simultaneously.

[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk

2013-06-21T19:32:36Z

Instead of centrally enabling and disabling subdevice master clocks in soc-camera core, let subdevice drivers do that themselves, using the V4L2 clock API and soc-camera convenience wrappers.

[media] sh-mobile-ceu-driver: support max width and height in DT

2013-06-21T19:25:08Z

Some CEU implementations have non-standard (larger) maximum supported width and height values. Add two OF properties to specify them. Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] sh-mobile-ceu-camera: add primitive OF support

2013-06-21T19:07:46Z

Add an OF hook to sh_mobile_ceu_camera.c, no properties so far. Booting with DT also requires platform data to be optional. Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] soc-camera: don't attach the client to the host during probing

2013-06-21T18:47:10Z

During client probing we only have to turn on the host's clock, no need to actually attach the client to the host. Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
