2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab1-1099/+0
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-05-15[media] soc-camera: Add plane layout information to struct soc_mbus_pixelfmtLaurent Pinchart1-0/+1
To compute the value of the v4l2_pix_format::bytesperline field, we need information about planes layout for planar formats. The new enum soc_mbus_layout conveys that information.

2012-05-15[media] soc_camera: Use soc_camera_device::sizeimage to compute buffer sizesLaurent Pinchart1-14/+3
Instead of computing the buffer size manually in the videobuf queue setup and buffer prepare callbacks, use the previously negotiated soc_camera_device::sizeimage value.

2012-01-06[media] soc-camera: remove redundant parameter from .set_bus_param()Guennadi Liakhovetski1-1/+1
The "pixfmt" parameter of the struct soc_camera_host_ops::set_bus_param() method is redundant, because at the time, when this method is called, pixfmt is guaranteed to be equal to icd->current_fmt->host_fmt->fourcc. Remove this parameter and update all drivers accordingly. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-11-07[media] drivers/media/video/atmel-isi.c: eliminate a null pointer dereferenceJulia Lawall1-1/+1
The variable isi might be null or might be freed at the point of the call to clk_put. pclk contains the value that isi->pclk is expected to point to. The semantic match that finds this problem is as follows: // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...) S1 else S2 when != E = E1 *E->f ... when any return ...; } else S3 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-09-06[media] media: vb2: change queue initialization orderMarek Szyprowski1-5/+15
This patch changes the order of operations during stream on call. Now the buffers are first queued to the driver and then the start_streaming method is called. This resolves the most common case when the driver needs to know buffer addresses to enable dma engine and start streaming. Additional parameter to start_streaming method have been added to simplify drivers code. The driver are now obliged to check if the number of queued buffers is high enough to enable hardware streaming. If not - it can return an error. In such case all the buffers that have been pre-queued are invalidated. This patch also updates all videobuf2 clients to work properly with the changed order of operations.

2011-09-06[media] media: vb2: dma contig allocator: use dma_addr instread of paddrMarek Szyprowski1-1/+1
Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested that this is the physical address in system memory. For most ARM platforms these two are the same, but this is not a generic rule. 'dma_addr' will also point better to dma-mapping api.

2011-09-06[media] media: vb2: change plane sizes array to unsigned int[]Marek Szyprowski1-1/+1
Plane sizes array was declared as unsigned long[], while unsigned int is more than enough for storing size of the video buffer. This patch reduces the size of the array by definiting it as unsigned int[].

2011-07-28[media] V4L: soc-camera: remove soc-camera bus and devices on itGuennadi Liakhovetski1-32/+32
Now that v4l2 subdevices have got their own device objects, having one more device in soc-camera clients became redundant and confusing.
