77e05ef7d4 media: vim2m: ensure that width is multiple of two
The copy logic assumes that the data width is multiple of two,
as this is needed in order to support YUYV.

There's no reason to force it to be 8-pixel aligned, as 2-pixel
alignment is enough.

de5c46ad48 media: vim2m: improve debug messages
1) Use two levels for debug:
	- level 1: setup stuff
	- level 2: add queue/dequeue messages

2) Better display the debug output, translating buffer
   type, fourcc and making some messages clearer.

1875a7c857 media: vim2m: add bayer capture formats
The vim2m device is interesting to simulate a webcam. As most
sensors are arranged using bayer formats, the best is to support
to output data using those formats.

So, add support for them.

All 4 8-bit bayer formats tested with:

	$ qvidcap -p &
	$ v4l2-ctl --stream-mmap --stream-out-mmap --stream-to-host localhost --stream-lossless --stream-out-hor-speed 1 -v pixelformat=RGGB

It was tested also with GStreamer with:

	$ gst-validate-1.0 filesrc location=some_video.mp4 ! qtdemux ! avdec_h264 ! videoconvert ! videoscale ! v4l2convert disable-passthrough=1 extra-controls="s,horizontal_flip=0,vertical_flip=0" ! bayer2rgb ! videoconvert ! xvimagesink

For all possible HFLIP/VFLIP values.

Add a flag 'FWHT_FL_I_FRAME' that indicates that
this is an I-frame. This requires incrementing
to version 3

This flag is needed for the upcoming stateless FWHT
decoder since it has to know if an encoded frame is
an I or a P frame.

ffaec3b21a media: exynos4-is: remove redundant check on type
The check to see if type is V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE is redundant
as this has been already checked at the start of the function and if
it's not that value then -ENOSYS is returned. Hence the sprintf can be
replaced by a simpler string copy.

35deee1418 media: sun6i: Add support for JPEG media bus format
The CSI controller can take raw data from the data bus and output it
directly to capture buffers. This can be used to support the JPEG media
bus format.

While the controller can report minimum and maximum bytes per line, it
has no way to report how many lines were captured in the last frame.
Thus, even when the on-bus data is framed correctly, we have no way to
accertain the actual amount of data captured, unless we scan the buffer
for JPEG EOI markers, or sequential zeros. For now we leave bytesused
alone, and leave it up to userspace applications to parse the data.

d31b282e2c media: sun6i: Fix CSI regmap's max_register
max_register is currently set to 0x1000. This is beyond the mapped
address range of the hardware, so attempts to dump the regmap from
debugfs would trigger a kernel exception.

Furthermore, the useful registers only occupy a small section at the
beginning of the full range. Change the value to 0x9c, the last known
register on the V3s and H3.

On the A31, the register range is extended to support additional
capture channels. Since this is not yet supported, ignore it for now.

smatch missed that if pipe->brx was NULL, then later on it will be

so smatch doesn't get confused.

CSI block in Allwinner A64 has similar features as like in H3,
but the default CSI_SCLK rate cannot work properly to drive the

The tested mod cock rate is 300 MHz and BSP vfe media driver is also
using the same rate. Unfortunately there is no valid information about
clock rate in manual or any other sources except the BSP driver. so more
faith on BSP code, because same has tested in mainline.

So, add support for A64 CSI block by setting updated mod clock rate.

6fd369dd1c media: vimc: fill in bus_info in media_device_info
It is good practice to fill in bus_info.

Also just use 'platform:vimc' when filling in the bus_info in querycap:
the bus_info has nothing to do with the video device name.

The v4l2_m2m_buf_copy_data helper is used to copy the buffer
metadata, such as its timestamp and its flags.

Therefore, the v4l2_m2m_buf_copy_metadata name is more clear
and avoids confusion with a payload data copy.

f0ef022c85 media: vim2m: allow setting the default transaction time via parameter
While there's a control to allow setting it at runtime, as the
control handler is per file handler, only the application setting
the m2m device can change it. As this is a custom control, it is
unlikely that existing apps would be able to set it.

Due to that, and due to the fact that v4l2-mem2mem serializes all
accesses to a m2m device, trying to setup two GStreamer
v4l2videoconvert instance at the same time will cause frame drops.

So, add an alternate way of setting its default via a modprobe parameter.

It doesn't make sense to have a per-device work queue, as the
scheduler should be called per file handler. Having a single
one causes failures if multiple streams are filtered by vim2m.

So, move it to be inside the context structure.

8aa153f103 media: vim2m: fix driver for it to handle different fourcc formats
Despite vim2m is reporting that it supports RGB565BE and YUYV,
that's not true.

Right now, it just says that it supports both format, but it
doesn't actually support them.

Also, horizontal flip is not properly implemented. It sounds
that it was designed to do a pseudo-horizontal flip using 8
tiles. Yet, as it doesn't do format conversion, the result
is a mess.

I suspect that it was done this way in order to save CPU time,
at the time of OMAP2 days.

That's messy and doesn't really help if someone wants to
use vim2m to test a pipeline.

Worse than that, the unique RGB format it says it supports is
RGB565BE, with is not supported by Gstreamer. That prevents
practical usage of it, even for tests.

So, instead, properly implement fourcc format conversions,
adding a few more RGB formats:

	- RGB and BGR with 24 bits
	- RGB565LE (known as RGB16 at gstreamer)

Also allows using any of the 5 supported formats as either
capture or output.

Note: The YUYV conversion routines are based on the conversion code
written by Hans de Goede inside libv4lconvert (part of v4l-utils),
released under LGPGL 2.1 (GPL 2.0 compatible).

Tested all possible format combinations except for RGB565BE,
as Gstreamer currently doesn't support it.

checking the payload size for plane 1, which doesn't exist.

Note: vfmt->buffers refers to the number of per-plane-buffers that
should be allocated. vfmt->planes refers to the number of planes
that make up an image. vfmt->planes may be > vfmt->buffers.
