The configuration of the pipeline and entities directly affects the
inputs required to each entity for the partition algorithm. Thus it
makes sense to involve those entities in the decision making process.
Extend the entity ops API to provide an optional .partition() operation.
This allows entities that affect the partition window to adapt the
window based on their configuration.
Entities implementing this operation must update the window parameter in
place, which will then be passed up the pipeline. This creates a process
whereby each entity describes what is required to satisfy the required
output to its predecessor in the pipeline.

As we develop the partition algorithm, we need to store more information
per partition to describe the phase and other parameters.
To keep this data together, further abstract the existing v4l2_rect
into a partition specific structure. As partitions only have horizontal
coordinates, store the left and width values only.
When generating the partition windows, operate directly on the partition
struct rather than copying and duplicating the processed data

s5p_jpeg_parse_hdr() but the member was not used by the caller, so it did
not matter. After applying patch
"media: s5p-jpeg: Don't use temporary structure in s5p_jpeg_buf_queue"
the unnecessary assignment started overwriting already assigned "size"

This adds the frontend driver for the MaxLinear MxL5xx family of tuner-
demodulators, as used on Digital Devices MaxS4/8 four/eight-tuner cards.
The driver was picked from the dddvb vendor driver package and - judging
solely from the diff - has undergone a 100% rework:
- Silly #define's used to pass multiple values to functions were
expanded. This resulted in macro/register names not being usable
anymore for such occurences, but makes the code WAY more read-,
understand- and maintainable.
- CamelCase was changed to kernel_case
- All typedef were removed
- Overall code style was fixed, besides >80char lines in _defs.h and
_regs.h, checkpatch is happy.
- Also, signal stat acquisition was made to comply with the DVB API
ways to do these things.
Permission to reuse and mainline the driver code was formally granted by
Ralph Metzler <rjkm@metzlerbros.de>.

It is known that MSI interrupts - while working quite well so far - can
still cause issues on some hardware platforms (causing I2C timeouts due
to unhandled interrupts). The msi variable/option is set to 1 by default.
So, add a Kconfig option prefixed with "EXPERIMENTAL" that will control
the default value of that modparam, defaulting to off for a better
user experience and (guaranteed) stable operation "per default".

While it seems valid that headers can carry simple oneline static inline
annotated functions, move them into their own header file to have the
overall code more readable. Also, keep them as header (and don't put in
a separate object) and static inline to help the compiler avoid
generating function calls.

This huge patch bumps the ddbridge driver to version 0.9.29. Compared to
the vendor driver package, DD OctoNET including GTL link support, and all
DVB-C Modulator card support has been removed since this requires large
changes to the underlying DVB core API, which should eventually be done
separately, and, after that, the functionality/device support can be added
back rather easy.
While the diff is rather large, the bump is mostly a big refactor of all
data structures. Yet, the MSI support (message signaled interrupts) is
greatly improved, also all currently available CI single/duo bridge cards
are fully supported.
More changes compared to the upstream driver:
- the DDB_USE_WORKER flag/define was removed, kernel worker functionality
will be used.
- coding style is properly fixed (zero complaints from checkpatch)
- all (not much though) CamelCase has been fixed to kernel_case
- (private) IOCTLs temporarily removed (which are mainly used to provide
rarely-used FPGA update functionality)
Great care has been taken to keep all previous changes and fixes (e.g.
kernel logging via dev_*(), pointer annotations and such) intact.
Permission to reuse and mainline the driver code was formally granted by
Ralph Metzler <rjkm@metzlerbros.de>.

Backmerge tag 'v4.13-rc5' into drm-next
Linux 4.13-rc5
There's a really nasty nouveau collision, hopefully someone can take a look
once I pushed this out.
As of 0.9.9b, the ddbridge code has been split from one single file
(ddbridge-core.c) into multiple files, with the purpose of taking care of
different topics, and to be able to reuse code in different kernel modules
(ddbridge.ko and octonet.ko). This applies the same code split, with a
notable difference:
In the vendor package, the split was done by moving all code parts into
separate files, and in the "main" code files (ddbridge.c and octonet.c),
a simple "#include ddbridge-core.c" was done.
In this patch, the same split (codewise) is done, but all resulting .c/.o
files will be handled by the makefile, with proper prototyping of all
shared functions done in ddbridge.h. To avoid conflicts wrt the global
space, the I2C functions and necessary prototypes for ddbridge-i2c.c are
moved into ddbridge-i2c.h, which is to be included wherever required.

Certain syscalls like recvmmsg support 64 bit timespec values for the
X32 ABI. The helper function compat_put_timespec converts a timespec
value to a 32 bit or 64 bit value depending on what ABI is used. The
v4l2 compat layer, however, is not designed to support 64 bit timespec
values and always uses 32 bit values. Hence, compat_put_timespec must
not be used.
Without this patch, user space will be provided with bad timestamp
values from the VIDIOC_DQEVENT ioctl. Also, fields of the struct
v4l2_event32 that come immediately after timestamp get overwritten,
namely the field named id.

The driver recently switched from handling page flip completion in the
DU vertical blanking handler to the VSP frame end handler to fix a race
condition. This unfortunately resulted in incorrect timestamps in the
vertical blanking events sent to userspace as vertical blanking is now
handled after sending the event.
To fix this we must reverse the order of the two operations. The easiest
way is to handle vertical blanking in the VSP frame end handler before
sending the event. The VSP frame end interrupt occurs approximately 50µs
earlier than the DU frame end interrupt, but this should not cause any
undue harm.
As we need to handle vertical blanking even when page flip completion is
delayed, the VSP driver now needs to call the frame end completion
callback unconditionally, with a new argument to report whether page
flip has completed.
With this new scheme the DU vertical blanking interrupt isn't needed
anymore, so we can stop enabling it.

The VSP supports both header and headerless display lists. The latter is
easier to use when the VSP feeds data directly to the DU in continuous
mode, and the driver thus uses headerless display lists for DU operation
and header display lists otherwise.
Headerless display lists are only available on WPF.0. This has never
been an issue so far, as only WPF.0 is connected to the DU. However, on
H3 ES2.0, the VSP-DL instance has both WPF.0 and WPF.1 connected to the
DU. We thus can't use headerless display lists unconditionally for DU
operation.
Implement support for continuous mode with header display lists, and use
it for DU operation on WPF outputs that don't support headerless mode.

When the display start interrupt occurs, we know that the hardware has
finished loading the active display list. The driver then proceeds to
recycle the list, assuming it won't be needed anymore.
This assumption holds true for headerless display lists, as the VSP
doesn't reload the list for the next frame if it hasn't changed.
However, this isn't true anymore for header display lists, as they are
loaded at every frame start regardless of whether they have been
updated.
To prepare for header display lists usage in display pipelines, we need
to postpone recycling the list until it gets replaced by a new one
through a page flip. The driver already does so in the frame end
interrupt handler, so all we need is to skip list recycling in the
display start interrupt handler.
While the active list can be recycled at display start for headerless
display lists, there's no real harm in postponing that to the frame end
interrupt handler in all cases. This simplifies interrupt handling as we
don't need to process the display start interrupt anymore.

This patch moves the subsampling value decoding read from the JPEG
header into its own function. This new function is called
s5p_jpeg_subsampling_decode() and returns true if it successfully
decodes the subsampling value, false otherwise.

If s5p_jpeg_parse_hdr() fails to parse the JPEG header, the passed
s5p_jpeg_q_data structure is not modified so there is no need to use a
temporary structure and the field-by-field copy can be avoided.

This patch modifies the s5p_jpeg_parse_hdr() function so it only
modifies the passed s5p_jpeg_q_data structure if the jpeg header parsing
is successful.
