2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab
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 Pinchart
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 Pinchart
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.

2012-01-11[media] convert drivers/media/* to use module_platform_driver()Axel Lin
This patch converts the drivers in drivers/media/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

2012-01-06[media] soc-camera: remove redundant parameter from .set_bus_param()Guennadi Liakhovetski
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>

2011-07-27[media] V4L: soc-camera: remove soc-camera bus and devices on itGuennadi Liakhovetski
Now that v4l2 subdevices have got their own device objects, having one more device in soc-camera clients became redundant and confusing. This patch removes those devices and the soc-camera bus, they used to reside on.

2011-07-27[media] Stop using linux/version.h on the remaining video driversMauro Carvalho Chehab
Standardize the remaining video drivers to return the API version for the VIDIOC_QUERYCAP version, instead of a per-driver version. Those drivers had the version updated more recently or are SoC drivers. Even so, it doesn't sound a good idea to keep a per-driver version control, so, let's use the per-subsystem version control instead.

Even though clk_put() is a no-op on most architectures it is not for some ARM implementations. To not fail on those, release the clock timer before freeing the surrounding structure.

2010-10-21[media] SoC Camera: add driver for OMAP1 camera interfaceJanusz Krzysztofik
This is a V4L2 driver for TI OMAP1 SoC camera interface. Both videobuf-dma versions are supported, contig and sg, selectable with a module option. The former uses less processing power, but often fails to allocate contignuous buffer memory. The latter is free of this problem, but generates tens of DMA interrupts per frame. If contig memory allocation ever fails, the driver falls back to sg automatically on next open, but still can be switched back to contig manually. Both paths work stable for me, even under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the oldest, least powerfull OMAP1 implementation. The interface generally works in pass-through mode. Since input data byte endianess can be swapped, it provides up to two v4l2 pixel formats per each of several soc_mbus formats that have their swapped endian counterparts. Boards using this driver can provide it with the following platform data: - if and what freqency clock is expected by an on-board camera sensor, - what is the maximum pixel clock that should be accepted from the sensor, - what is the polarity of the sensor provided pixel clock, - if the interface GPIO line is connected to a sensor reset/powerdown input and what is the input polarity. Created and tested against linux-2.6.36-rc5 on Amstrad Delta.
