This uses the ARCH_MXC specific iram_alloc API to allocate a work buffer in the SoC's on-chip SRAM and sets up the AXI_SRAM_USE register. In the future, the allocation will be converted to use the genalloc API. Signed-off-by:

Add support for loading a raw firmware with 16-bit chars ordered in little-endian 64-bit words, corresponding to the memory access pattern of CODA7 and above: When writing the boot code into the code download register, the chars have to be reordered back. Signed-off-by:

New mem-to-mem video drivers should use V4L2_CAP_VIDEO_M2M capability, rather than ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags, as outlined in commit a1367f1b. Signed-off-by:

Check against q->fileio to see if the queue owner should be set or not. The former check against the return value of read or write is wrong, since read/write can return an error, even if the queue is in streaming mode. For example, EAGAIN when in non-blocking mode. Signed-off-by:

The ioctl validity checks have been improved and now take vfl_type and vfl_dir into account. During the 2012 Media Workshop it was decided that these improved v4l2 core checks should be added as they simplified drivers and made drivers behave consistently. Signed-off-by:

These will be used by v4l2-dev.c to improve ioctl checking. I.e. ioctls for capture should return -ENOTTY when called for an output device. Signed-off-by:

While the documentation says that VIDIOC_CROPCAP is compulsory for all video capture and output devices, in practice VIDIOC_CROPCAP is only implemented for devices that can do cropping and/or scaling. Update the documentation to no longer require VIDIOC_CROPCAP if the driver does not support cropping or scaling or non-square pixels. Signed-off-by:

It was not entirely obvious that the sequence count should also be set for output devices. Also made it more explicit that this sequence counter counts frames, not fields. Signed-off-by:

These have been replaced by new defines without the "CUSTOM_" part. Get rid of the old ones. Signed-off-by:
-
Hans Verkuil authored
The 'custom' timings are no longer just for custom timings, but also for standard CEA/VESA timings. So rename to V4L2_IN/OUT_CAP_DV_TIMINGS. The old define is still kept for backwards compatibility. This decision was taken during the 2012 Media Workshop. Signed-off-by:

Currently the core code looks at tvnorms to see whether ENUMSTD or G_PARM should be enabled. This is not a good check for drivers that support the STD API on one input and the DV Timings API on another. In that case tvnorms may be 0. Instead check whether s_std is present (for ENUMSTD) or whether g_std or current_norm is present for g_parm. Also, in the enumstd core function return ENODATA if tvnorms is 0, because in that case the current input does not support the STD API and ENUMSTD should return ENODATA for that. Signed-off-by:
-
Hans Verkuil authored
ENODATA should be returned if the API used for getting, changing, querying or enumerating the current video timings is not supported by the current input or output. This was decided during the 2012 Media Workshop. Signed-off-by:

A number of old drivers still had the experimental tag. Time to remove it. It concerns the following drivers: VIDEO_TLV320AIC23B USB_STKWEBCAM VIDEO_CX18 VIDEO_CX18_ALSA VIDEO_ZORAN_AVS6EYES DVB_USB_AF9005 MEDIA_TUNER_TEA5761 VIDEO_NOON010PC30 This decision was taken during the 2012 Media Workshop.

V4L2_BUF_TYPE_PRIVATE was used in these driver for internal purposes. It turned out though that it wasn't used at all, so it could be removed. I know it was used in the past, but clearly later changes made this obsolete. Signed-off-by:

This buffer type isn't used at all, and since it is effectively undefined what it should do it is deprecated. The define still exists, but any internal support for such buffers is removed. The decisions to deprecate this was taken during the 2012 Media Workshop. Signed-off-by:

- S/TRY_FMT should always succeed, unless an invalid type field is passed in. - TRY_FMT should give the same result as S_FMT, all other things being equal. - ENUMFMT may return different formats for different inputs or outputs. This was decided during the 2012 Media Workshop. Signed-off-by:

During the 2012 Media Workshop it was decided to split off the control definitions into their own v4l2-controls.h header, included by videodev2.h. Because controls make up such a large part of V4L2 they made it hard to read videodev2.h. Splitting off the control definitions makes life easier. Signed-off-by:

If start_streaming() fails (e.g. out of memory) the driver needs to rewind the start procedure. This implies possibly stopping the device and clearing the buffer queue. Signed-off-by:

The driver was expecting to get a valid pixelformat on s_fmt and try_fmt. This is wrong, since the user may pass a bitmask and expect the driver to change it, returning a valid (fourcc) pixelformat. This problem was spotted by v4l2-compliance. Signed-off-by:
