The g_mbus_fmt video op is a duplicate of the pad op. Replace all uses by the get_fmt pad op and remove the video op. Signed-off-by:

There are a few lines longer than 80 cols for no good reason. Fix them sooner than latter, making checkpatch.pl happy. Cc: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: -

Ensure that buffers are allocated from the DMA32 zone since this device only handles 32 bit DMA addresses. Signed-off-by:

The dt3155 code is now in good shape, so move it out of staging into drivers/media/pci. Mark in MAINTAINERS that I'll do Odd Fixes for this driver. Signed-off-by:
-
Hans Verkuil authored
The dt3155 together with the J1 breakout cable supports 4 inputs. Add support for all inputs VID0 - VID3. Note that input VID0 is shared with input J2. Signed-off-by:

Fix various v4l2-compliance issues regarding format handling. Main problem was a missing colorspace value and incorrect format checks. This driver supports a single format only. Signed-off-by:
-
Hans Verkuil authored
There is no need for CONFIG_DT3155_CCIR to select between 50/60 Hz, that's why we have s_std. Since this is a simple framegrabber there is no need for g/s_parm. The frame period can be obtained via ENUMSTD instead. Signed-off-by:

Hans Verkuil authored
Don't start streaming when a buffer is queued, instead implement the start_streaming op and do it there, leaving it up to the vb2 framework to call start_streaming when enough buffers have been queued. And don't stop streaming from within the interrupt routine, instead do that in stop_streaming. Signed-off-by:
-
Hans Verkuil authored
No need to do this as a config option. Just support both MMAP and read() methods like any other driver. Signed-off-by:
-
Hans Verkuil authored
Instead of initializing the vb2_queue in open (and freeing in release) do this in probe/remove instead. And as a bonus use the vb2 helper functions to greatly simplify the driver. Signed-off-by:
-
Hans Verkuil authored
For some weird reason an attempt is made in init_board to capture a single frame. No clue why, and everything works fine without that code. I suspect this was test code that was never removed. Signed-off-by:
-
Hans Verkuil authored
No idea what the purpose is of these functions. I suspect this was used once upon a time to pre-allocate buffer memory. But the allocated memory isn't used anywhere anymore, so just remove this code. Signed-off-by:
-
Hans Verkuil authored
Add struct v4l2_device and register it. Also move the request_irq to probe instead of doing that in open(). Signed-off-by:

The REG_CTRL0 register was never written if this format was selected, instead an error was logged and whatever was last set in that register was used. Surprisingly, that seems to work if YUYV was selected, but we should program this register explicitly. Signed-off-by:

Hans Verkuil authored
I cannot get this format to work, the colors keep coming out wrong. Since this has never worked I just drop support for this. Signed-off-by:

These were calculated incorrectly for the planar formats. Signed-off-by:
-
Hans Verkuil authored
Even though the format is Y'CbCr, the colorspace used by the sensor is almost certainly SRGB. The sensor is also not generating JPEG data, so it makes no sense to use V4L2_COLORSPACE_JPEG here. Signed-off-by:
-
Hans Verkuil authored
This driver appeared to support the JPEG format when in reality that was just dead code. Remove it. Signed-off-by:
-
Hans Verkuil authored
The dma-vmalloc implementation didn't support planar formats, but with a little bit of refactoring that is easy to fix. Signed-off-by:
-
Hans Verkuil authored
If start_streaming fails or stop_streaming is called, then all queued buffers need to be given back to vb2. This prevents vb2 from calling WARN_ON when it detects that this is not done correctly. Signed-off-by:

Add VB2_DMABUF and VIDIOC_EXPBUF support. Also add VB2_USERPTR support for the vmalloc DMA mode which was missing for no good reason. Signed-off-by:

This fixes the final v4l2-compliance warning. Signed-off-by:
-
Hans Verkuil authored
Use the V4L2 core locking system instead of rolling your own. Switch to the vb2 fop and ioctl helpers to get rid of a lot of code. This also made it easy to add VB2_READ to the DMA modes, since you get read() for free with vb2 and these helpers. Finally remove the users field: this information is also available from the core framework, no need to keep track of it in the driver. Signed-off-by:
-
Hans Verkuil authored
Now that this driver uses v4l2_fh, it is trivial to add support for control events. Again, this fixes a v4l2-compliance failure. Signed-off-by:
-
Hans Verkuil authored
Use struct v4l2_fh to represent a filehandle. This fixes the missing g/s_priority handling of this driver that v4l2-compliance complained about. Signed-off-by:
-
Hans Verkuil authored
No controls were reported, even though the ov7670 does have controls. Two reasons for this: the v4l2_ctrl_handler_init() call must come before the ov7670 is loaded (otherwise the ov7670 won't know that its controls should be added to the bridge driver), and the v4l2_ctrl_handler_free() call at the end should only be called if the ret value is non-zero (otherwise you would just free all the controls that were just added).

The colorspace field wasn't filled in properly. This fixes a v4l2-compliance failure. Signed-off-by:

The width and height should be checked in the enum_frame_interval op. This fixes a v4l2-compliance failure. Signed-off-by:

TV standards make no sense for webcam drivers, so drop these dummy functions. This stops v4l2-compliance from complaining about this. Signed-off-by:

The bus_info field of struct v4l2_querycap wasn't filled in and v4l2-compliance complained about that. Fix this. Signed-off-by:

We must set timestamp_flags in vb2_queue otherwise vb2 will complain loudly about it. Signed-off-by:

Hans Verkuil authored
Running v4l2-compliance on my usbtv stick revealed two failures: 1) Correct handling of CREATE_BUFS in usbtv_queue_setup was missing. Added this. 2) The sequence counter wasn't reset to 0 when starting streaming. Signed-off-by:
