As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.
I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.
Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.
There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.
One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.
This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.
A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

Change the I/O endpoint handling of the mceusb driver to respect the endpoint
type reported by device (bulk/interrupt), rather than treating all endpoints
as type interrupt, which breaks devices using bulk endpoints when connected
to a xhci controller. Accordingly, change the function calls to initialize
an endpoint's transfer pipe and urb handlers to use the correct function based
on the endpoint type.

This event indicates that the video device has encountered
a source parameter change during runtime. This can typically be a
resolution change detected by a video decoder OR a format change
detected by an input connector.
This needs to be nofified to the userspace and the application may
be expected to reallocate buffers before proceeding. The application
can subscribe to events on a specific pad or input port which
it is interested in.

Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:
- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;
- v6 firmware will return the number of consumed bytes, but will not
include the padding ("stuffing") bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;
The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to

- Honor return values from vb2_reqbufs on REQBUFS(0).
- Do not set the number of allocated buffers to 0 if userspace tries
to request buffers again without freeing them.
- There is no need to verify correct instance state on reqbufs, as we will
verify this in queue_setup().
- There is also no need to verify that vb2_reqbufs() was able to allocate enough
buffers (pb_count) and call buf_init on that many buffers (i.e. dst_buf_count
is at least pb_count), because this will be verified by second queue_setup()
call as well and vb2_reqbufs() will fail otherwise.

corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on "display status". Display status reflects the status
of the destination buffer, not source.
This used to work for firmwares version <= 6, because in addition to the above,
we'd check the decoded frame type register, which was set to "skipped" if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware >=7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).
To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. "decode status". The decode status register
values are confusing, because in its case "display" means "a frame has been
outputted to a destination buffer". We should copy if "decode and display"
is returned in it. This also works on <= v6 firmware, which behaves in the same
way with regards to decode status register.

Auto BLC and BLC digital offset are disabled when enabling the test
pattern and must be restored when disabling it. The driver does so by
calling the set control handler on the auto BLC and BLC offset controls,
but this programs the hardware with the new value of those controls, not
the current value. Fix this by writing to the registers directly.

The digital side of the Black Level Calibration (BLC) function must be
disabled when generating a test pattern to avoid artifacts in the image.
The driver disables BLC correctly at the hardware level, but the feature
gets reenabled by v4l2_ctrl_handler_setup() the next time the device is
powered on.
Fix this by marking the BLC controls as inactive when generating a test
pattern, and ignoring control set requests on inactive controls.

Add selection ioctl ops. For VPE, cropping makes sense only for the input to
VPE(or V4L2_BUF_TYPE_VIDEO_OUTPUT/MPLANE buffers) and composing makes sense
only for the output of VPE(or V4L2_BUF_TYPE_VIDEO_CAPTURE/MPLANE buffers).
For the CAPTURE type, V4L2_SEL_TGT_COMPOSE results in VPE writing the output
in a rectangle within the capture buffer. For the OUTPUT type, V4L2_SEL_TGT_CROP
results in selecting a rectangle region within the source buffer.
Setting the crop/compose rectangles should successfully result in
re-configuration of registers which are affected when either source or
destination dimensions change, set_srcdst_params() is called for this purpose.

Some parameters of the VPE descriptors were understood incorrectly. They are now
fixed. The fixes are explained as follows:
- When adding an inbound data descriptor to the VPDMA descriptor list, we intend
to use c_rect as the cropped region fetched by VPDMA. Therefore, c_rect->width
shouldn't be used to calculate the line stride, the original image width
should be used for that. We add a 'width' argument which gives the buffer
width in memory.
- frame_width and frame_height describe the complete width and height of the
client to which the channel is connected. If there are multiple channels
fetching data and providing to the same client, the above 2 arguments should
be the width and height of the region covered by all the channels. In the case
where there is only one channel providing pixel data to the client
(like in VPE), frame_width and frame_height should be the cropped width and
cropped height respectively. The calculation of these params is done in the
vpe driver now.
- start_h and start_v is also used in the case of multiple channels to describe
where each channel should start filling pixel data. We don't use this in VPE,
and pass 0s to the vpdma_add_in_dtd() helper.
- Some minor changes are made to the vpdma_add_out_dtd() helper. The c_rect
param is used for specifying the 'composition' target, and 'width' is added
to calculate the line stride.

For OMAP and DRA7x, we generally allocate video and graphics buffers through
omapdrm since the corresponding omap-gem driver provides DMM-Tiler backed
contiguous buffers. omapdrm is a dma-buf exporter. These buffers are used by
other drivers in the video pipeline.
Add VB2_DMABUF flag to the io_modes of the vb2 output and capture queues. This
allows the driver to import dma shared buffers.

vpe fops(vpe_open in particular) should be called only when VPDMA firmware
is loaded. File operations on the video device are possible the moment it is
registered.
Currently, we register the video device for VPE at driver probe, after calling
a vpdma helper to initialize VPDMA and load firmware. This function is
non-blocking(it calls request_firmware_nowait()), and doesn't ensure that the
firmware is actually loaded when it returns.
We remove the device registration from vpe probe, and move it to a callback
provided by the vpe driver to the vpdma library, through vpdma_create().
The ready field in vpdma_data is no longer needed since we always have firmware
loaded before the device is registered.
A minor problem with this approach is that if the video_register_device
fails(which doesn't really happen), the vpe platform device would be registered.
however, there won't be any v4l2 device corresponding to it.

Convert the saa7134 driver to vb2.
Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is
disabled. The DMA hardware only supports DMAing full pages, and in the
USERPTR memory model the first and last scatter-gather buffer is almost
never a full page.
In practice this means that we can't use the VB2_USERPTR mode.
This has been tested with raw video, compressed video, VBI, radio, DVB and
video overlays.
Unfortunately, a vb2 conversion is one of those things you cannot split
up in smaller patches, it's all or nothing. This patch switches the whole
driver over to vb2, using the vb2 ioctl and fop helper functions.
