The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer than 16 bits. However, we do have specific definitions for smaller sample sizes. Therefore, this note is redundant from the API point of view. Currently only two drivers, am437x and davinci, use the V4L2_PIX_FMT_SBGGR16 pixelformat currently. The sampling precision is understood to be 16 bits in all current cases. Remove the note on sampling precision. Signed-off-by:

The other raw bayer formats had a single sample depth dependent definition whereas the 8-bit formats had one page for each. Unify the documentation of the 8-bit formats. Signed-off-by:

- Explicitly state that the most significant n bits are zeroed on 10 and 12 bpp formats. - Remove extra comma from the last entry of the format list - Add a missing colon before a list - Use figures versus word numerals consistently Signed-off-by:

The number of high order bits in samples was documented to be 6 for 12-bit data. This is clearly wrong, fix it. Signed-off-by:

The 10-bit packed raw bayer format documented that the data of the first pixel of a four-pixel group was found in the first byte and the two highest bits of the fifth byte. This was not entirely correct. The two bits in the fifth byte are the two lowest bits. The second pixel occupies the second byte and third and fourth least significant bits and so on. Signed-off-by:

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:

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:

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.

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:

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. Signed-off-by:

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:

Move the functions in the file to be regrouped into meaningful blocks : 1. pxa camera core handling functions, manipulating the herdware 2. videobuf2 functions, dealing with video buffers 3. video ioctl (vidioc) related functions 4. driver probing, removal, suspend and resume This patch doesn't modify a single line of code.

Convert pxa_camera from videobuf to videobuf2. As the soc_camera was already compatible with videobuf2, the port is quite straightforward. The special case of this code in which the vb2 to prepare is "too big" in terms of size for the new capture format, the pxa_camera will fail. Signed-off-by:

Remove the soc_camera adherence. Mostly the change removes the power manipulation provided by soc_camera, and instead : - powers on the sensor when the s_power control is activated - powers on the sensor in initial probe - enables and disables the MCLK provided to it in power on/off This patch also drops support for inverters on synchronisation and clock lines. It is assumed, if any board ever needs such inverters, support for them can be added in the future Acked-by:

This patch adds V4L2 HVA (Hardware Video Accelerator) video encoder driver for STMicroelectronics SoC. It uses the V4L2 mem2mem framework. This patch only contains the core parts of the driver: - the V4L2 interface with the userland (hva-v4l2.c) - the hardware services (hva-hw.c) - the memory management utilities (hva-mem.c) This patch doesn't include the support of specific codec (e.g. H.264) video encoding: this support is part of subsequent patches.
