Arnd Bergmann b82e39f856 [media] pulse8-cec: avoid uninitialized data use
Building with -Wmaybe-uninitialized reveals the use on an uninitialized
variable containing the physical address of the device whenever
firmware before version 2 is used:

drivers/staging/media/pulse8-cec/pulse8-cec.c: In function 'pulse8_connect':
drivers/staging/media/pulse8-cec/pulse8-cec.c:447:2: error: 'pa' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This sets the address to CEC_PHYS_ADDR_INVALID in this case, so we don't
try to write back the uninitialized data to the device.

Since we really don't want to have to use any of the soc-camera code this patch
copies the relevant code and data structures from soc_mediabus and renames it to pxa_mbus_*.

The large table of formats has been culled a bit, removing formats that are not supported
by this driver.

Laurent Pinchart fd44aa9a25 [media] v4l: rcar-fcp: Don't force users to check for disabled FCP support
The rcar_fcp_enable() function immediately returns successfully when the
FCP device pointer is NULL to avoid forcing the users to check the FCP
device manually before every call. However, the stub version of the
function used when the FCP driver is disabled returns -ENOSYS
unconditionally, resulting in a different API contract for the two
versions of the function.

As a user that requires FCP support will fail at probe time when calling
rcar_fcp_get() if the FCP driver is disabled, the stub version of the
rcar_fcp_enable() function will only be called with a NULL FCP device.
We can thus return 0 unconditionally to align the behaviour with the
normal version of the function.

Robert Jarzmik fcdf9bbc91 [media] media: platform: pxa_camera: change stop_streaming semantics
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.

Robert Jarzmik 283e4a8299 [media] media: platform: pxa_camera: make a standalone v4l2 device
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.

Robert Jarzmik 226ad6a18f [media] media: platform: pxa_camera: remove set_selection
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.

Robert Jarzmik 295ab497d6 [media] media: platform: pxa_camera: make printk consistent
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.

Robert Jarzmik b36bcbd6f2 [media] media: platform: pxa_camera: introduce sensor_call
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.

Robert Jarzmik 6f28435d1c [media] media: platform: pxa_camera: trivial move of functions
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.
