Only cx231xx-video needs linux/version.h, due to KERNEL_VERSION macro, that is used by V4L2 API. This patch moves the KERNEL_VERSION to its proper place and starts with 0,0,1. There are still much more to be fixed on later patches Signed-off-by: -

If usb_interface.dev is used as dev parameter for v4l2_device_register v4l2_dev.name contains the v4l driver/module name and usb device and interface instead of a simple "usb x-y". It also matches the recommendation to set the parent devices for usb drivers. Signed-off-by:

With the i.MX31 transition to clkdev clock names have changed, but mistakenly the "mx3-camera.0" has been registered with a non-NULL connection ID, which is not necessary, since this is the only clock, used by the capture interface driver. Fix the clock definition and the driver to use NULL as a connection ID. Signed-off-by:

Setup the i2c clock speed to be definable on a per-board basis. This allows us to explicitly set the clock speed to 30 KHz on the 950q, and also gets rid of code which sets it on a basis of what chip the i2c master is talking to at any given time (which could have caused issues because i2c slaves should never receive commands at a clock higher than their supported clock speed).

Any time a struct (especially one not defined by this driver) is allocated, we MUST zero its underlying storage. This makes our usage of the struct predictable and robust against future changes where fields might be added that we don't know about. Failing to do this with tuner_setup left the config field uninitialized which then caused trouble with the tuner type used for HVR-1950 devices. Signed-off-by:

MT9M001 datasheet says, that the data is ready on the falling edge of the pixel clock, but the driver wrongly sets the SOCAM_PCLK_SAMPLE_RISING flag. Changing this doesn't seem to produce any visible difference, still, it is better to comply to the datasheet. Reported-by:

soc-camera re-uses struct devices multiple times in calls to device_register(), therefore it has to reset the embedded struct kobject to avoid the "tried to init an initialized object" error, which then also erases its name. Now with the transition to kobject's name for device names, we have to re-initialise the name before each call to device_register(). Signed-off-by:

pxa_dma_update_sg_tail() is called only once, runs exactly the same loop as the caller and has to recalculate the last element in an sg-list, that the caller has already calculated. Eliminate redundancy by merging the two loops and re-using the calculated pointer. This also saves a bit of performance which is always good during video-capture. Signed-off-by:

The last buffer queued will often overrun, as the DMA chain is finished, and the time the dma irq handler is activated, the QCI fifos are filled by the sensor. The fix is to ignore the overrun condition on the last queued buffer, and restart the capture only on intermediate buffers of the chain. Moreover, a fix was added to the very unlikely condition where in YUV422P mode, one channel overruns while another completes at the very same time. The capture is restarted after the overrun as before, but the other channel completion is now ignored. Signed-off-by:

The DMA transfers in pxa_camera showed some weaknesses in multiple queued buffers context : - poll/select problem The bug shows up with capture_example tool from v4l2 hg tree. The process just "stalls" on a "select timeout". - multiple buffers DMA starting When multiple buffers were queued, the DMA channels were always started right away. This is not optimal, as a special case appears when the first EOF was not yet reached, and the DMA channels were prematurely started. - Maintainability DMA code was a bit obfuscated. Rationalize the code to be easily maintainable by anyone. - DMA hot chaining DMA is not stopped anymore to queue a buffer, the buffer is queued with DMA running. As a tribute, a corner case exists where chaining happens while DMA finishes the chain, and the capture is restarted to deal with the missed link buffer. This patch attemps to address these issues / improvements. create mode 100644 Documentation/video4linux/pxa_camera.txt Signed-off-by:

All planes were PAGE aligned (ie. 4096 bytes aligned). This is not consistent with YUV422 format, which requires Y, U and V planes glued together. The new implementation forces the alignement on 8 bytes (DMA requirement), which is almost always the case (granted by width x height being a multiple of 8). The test cases include tests in both YUV422 and RGB565 : - a picture of size 111 x 111 (cross RAM pages example) - a picture of size 1023 x 4 in (under 1 RAM page) - a picture of size 1024 x 4 in (exactly 1 RAM page) - a picture of size 1025 x 4 in (over 1 RAM page) - a picture of size 1280 x 1024 (many RAM pages) Signed-off-by:

Due to DMA constraints, the DMA chain always transfers bytes from the QCI fifos to memory in 8 bytes units. In planar formats, that could mean 0 padding between Y and U plane (and between U and V plane), which is against YUV422P standard. Therefore, a frame size is required to be a multiple of 16 (so U plane size is a multiple of 8). It is enforced in try_fmt() and set_fmt() primitives, be aligning height then width on 4 multiples as need be, to reach a 16 multiple. Signed-off-by:
