Earlier version of dma-contig allocator in user ptr mode assumed that in

Commit e15dab752d4c588544ccabdbe020a7cc092e23c8 introduced correct support
for converting userpage to dma address, but unfortunately it broke the

physical frame has no struct page associated with it (this happens if one

This commit restores support for such cases.

upstream: [media] smiapp: Fix determining the need for 8-bit read access

8-bit reads are needed in some cases; however the condition used was wrong.
Regular access (register width) was used if:

len == SMIAPP_REG_8BIT && !only8

This causes 8-bit read access to be used always. The operator should be ||
instead: regular access can be used for 8-bit reads OR if allowed otherwise.

upstream: [media] vb2: fix compiler warning

When compiling this for older kernels using the compatibility build

upstream: [media] v4l2-ioctl.c: fix sparse __user-related warnings

Fix the use of __user in the check_array_args() prototype: instead of
using 'void * __user *' you should use 'void __user **' for sparse to
understand this correctly.

This also required the use of __force in the '*kernel_ptr = user_ptr'
assignment.

Also replace a wrong cast (void *) with the correct one (void **)
in check_array_args().

This fixes these sparse warnings:

The notify function is a void function, yet the v4l2_subdev_notify

Replace the define by a static inline function and move it to
v4l2-device.h, which is where it belongs since it needs to know the
v4l2_device struct. This wasn't a problem when it was a define, but

upstream: [media] gpsca: remove the risk of a division by zero

As reported by Coverity, there's a potential risk of a division
by zero on some calls to jpeg_set_qual(), if quality is zero.

As quality can't be 0 or lower than that, adds an extra clause
to cover this special case.

upstream: [media] v4l: ti-vpe: Set correct field parameter for output and capture buffers

The vpe driver wasn't setting the correct field parameter for dequed CAPTURE
type buffers for the case where the captured output is progressive.

Set the field to V4L2_FIELD_NONE for the completed destination buffers when
the captured output is progressive.

For OUTPUT type buffers, a queued buffer's field is forced to V4L2_FIELD_NONE
if the pixel format(configured through s_fmt for the buffer type
V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE specifies) the field type isn't interlaced.
If the pixel format specified was V4L2_FIELD_ALTERNATE, and the queued buffer's
field isn't V4L2_FIELD_TOP or V4L2_FIELD_BOTTOM, the vb2 buf_prepare op returns
an error.

This ensures compliance, and that the dequeued output and captured buffers
contain the field type that the driver used internally.

upstream: [media] v4l: ti-vpe: Allow usage of smaller images

The minimum width and height for VPE input/output was kept as 128 pixels. VPE
doesn't have a constraint on the image height, it requires the image width to
be at least 16 bytes.

Change the minimum supported dimensions to 32x32. This allows us to de-interlace
qcif content. A smaller image size than 32x32 didn't make much sense, so stopped
at this.

upstream: [media] v4l: ti-vpe: Use video_device_release_empty

The video_device struct is currently embedded in the driver data struct vpe_dev.
A vpe_dev instance is allocated by the driver, and the memory for the vfd is a
part of this struct.

The v4l2 core, however, manages the removal of the vfd region, through the
video_device's .release() op, which currently is the helper
video_device_release. This causes memory corruption, and leads to issues when
we try to re-insert the vpe module.

Use the video_device_release_empty helper function instead.

upstream: [media] v4l: ti-vpe: Make sure in job_ready that we have the needed number of dst_bufs

VPE has a ctrl parameter which decides how many mem to mem transactions the
active job from the job queue can perform.

The driver's job_ready() made sure that the number of ready source buffers are
sufficient for the job to execute successfully. But it didn't make sure if
there are sufficient ready destination buffers in the capture queue for the
VPE output.

If the time taken by VPE to process a single frame is really slow, then it's
possible that we don't need to imply such a restriction on the dst queue, but
really fast transactions(small resolution, no de-interlacing) may cause us to
hit the condition where we don't have any free buffers for the VPE to write on.

Add the extra check in job_ready() to make sure we have the sufficient amount
of destination buffers.

upstream: [media] v4l2-common: fix warning when used on userpace

As reported by Linus, make headers_check is reporting:
   usr/include/linux/v4l2-common.h:72: found __[us]{8,16,32,64} type without #include <linux/types.h>

   which seems to have come in through commits 777f4f85b75f1 and
   254a47770163f.

That happens because struct v4l2_edid should be visible by both
subdev and V4L2 APIs. So, it was moved to v4l2-common.h.

As Linus pointed, the proper fix is to just add an include for
linux/types.h at v4l2-common.h.
