Two arrays of size 'max number of planes' have a hardcoded size instead of using TPG_MAX_PLANES. Fix that, since TPG_MAX_PLANES will be increased later on. Signed-off-by:

The plane size check was hardcoded to plane 0 instead of using the plane index. This failed when using the NV61M format which has a larger plane size for the second plane compared to the first plane. Signed-off-by:

If the vivid driver is loaded in multiplanar mode, then the capture overlay functionality should be disabled. This wasn't fully done, which led to v4l2-compliance errors. Signed-off-by:

Instead of forcing drivers to implement empty clock operations, make them optional. v4l2 clock registration in the soc-camera core should probably be conditionned on the availability of those operations, but careful review and/or testing of all drivers would be needed, so that should be a separate step.

Add device tree support for ov2640. In device tree, user needs to provide the master clock (xvclk). User can add the reset/pwdn pins if they have. Cc: devicetree@vger.kernel.org Signed-off-by:

In async probe, there is a case that ov2640 is probed before the host device which provided 'mclk'. To support this async probe, we will get 'mclk' at first in the probe(), if failed it will return -EPROBE_DEFER. That will let ov2640 wait for the host device probed. Signed-off-by:

icd->control is the sub device dev, i.e. i2c device. icd->pdev is the soc camera device's device. To be consitent with power() function, we will call reset() with icd->control as well. Signed-off-by:

V4L2 clocks, e.g. used by camera sensors for their master clock, do not have to be supplied by a different V4L2 driver, they can also be supplied by an independent source. In this case the standart kernel clock API should be used to handle such clocks. This patch adds support for such cases. Signed-off-by:

All uses of the v4l2_clk API so far only register one clock with a fixed name. This allows us to get rid of it, which also will make CCF and DT integration easier. Signed-off-by:

The check_ext_ctrls() function in v4l2-ioctl.c checks if all controls in the control array are from the same control class as c->ctrl_class. However, that check should only be done if c->ctrl_class != 0. A 0 value means that this restriction does not apply. So return 1 (OK) if c->ctrl_class == 0. Found by running v4l2-compliance on the uvc driver. Signed-off-by:

Commit c5036d61 ("media: au0828: drop vbi_buffer_filled() and re-use buffer_filled()") broke video and vbi streaming. The vb2_buffer struct was copied instead of taking a pointer to it, but vb2_buffer_done() needs the real object, not a copy, since it is hooking the buffer into a different list. Signed-off-by:

All other drivers using the TI_ST infrastructure use 'depends on' for this symbol, and it makes no sense to only enable that if CONFIG_NET is enable, because the radio driver also depends on CONFIG_NET itself: ERROR: "skb_queue_purge" [drivers/media/radio/wl128x/fm_drv.ko] undefined! ERROR: "skb_push" [drivers/media/radio/wl128x/fm_drv.ko] undefined! ERROR: "skb_pull" [drivers/media/radio/wl128x/fm_drv.ko] undefined! Making the driver dependency explicit solves randconfig build problems and makes it more obvious to the reader. Signed-off-by:

The documentation says that the bytesperline field in v4l2_pix_format refers to the largest plane in the case of planar formats (i.e. multiple planes stores in a single buffer). For almost all planar formats the first plane is also the largest (or equal) plane, except for two formats: V4L2_PIX_FMT_NV24/NV42. For this YUV 4:4:4 format the second chroma plane is twice the size of the first luma plane. Looking at the very few drivers that support this format the bytesperline value that they report is actually that of the first plane and not that of the largest plane. Rather than fixing the drivers it makes more sense to update the documentation since it is very difficult to use the largest plane for this. You would have to check what the format is in order to know to which plane bytesperline belongs, which makes calculations much more difficult. This patch updates the documentation accordingly.
