commit 49dc762cffd8305a861ca649e82dc5533b3e3344 upstream.
The driver should really call dm365_isif_setup_pinmux() through a callback,
but uses a hack to include a davinci specific machine header file when
compile testing instead. This works almost everywhere, but not on the
ARM omap1 platform, which has another header named mach/mux.h. This
causes a build failure:

Exclude omap1 from compile-testing, under the assumption that all others
still work.

commit 107927fa597c99eaeee4f51865ca0956ec71b6a2 upstream.
In imx_media_create_csi_of_links(), the 'struct v4l2_fwnode_link' must
be cleared for each endpoint iteration, otherwise if the remote port
has no "reg" property, link.remote_port will not be reset to zero.
This was discovered on the i.MX53 SMD board, since the OV5642 connects
directly to ipu1_csi0 and has a single source port with no "reg"
property.

commit 904371f90b2c0c749a5ab75478c129a4682ac3d8 upstream.
On i.MX6, the nearest upstream entity to the CSI can only be the
CSI video muxes or the Synopsys DW MIPI CSI-2 receiver.
However the i.MX53 has no CSI video muxes or a MIPI CSI-2 receiver.
So allow for the nearest upstream entity to the CSI to be something
other than those.

commit 4bc1ab41eee9d02ad2483bf8f51a7b72e3504eba upstream.
Move upstream stream off to just after receiving the last EOF completion
and disabling the CSI (and thus before disabling the IDMA channel) in
csi_stop(). For symmetry also move upstream stream on to beginning of
csi_start().
Doing this makes csi_s_stream() more symmetric with prp_s_stream() which
will require the same change to fix a hard lockup.

commit 2e0fe66e0a136252f4d89dbbccdcb26deb867eb8 upstream.
Disable the CSI immediately after receiving the last EOF before stream
off (and thus before disabling the IDMA channel). Do this by moving the
wait for EOF completion into a new function csi_idmac_wait_last_eof().
This fixes a complete system hard lockup on the SabreAuto when streaming
from the ADV7180, by repeatedly sending a stream off immediately followed
by stream on:
while true; do v4l2-ctl -d4 --stream-mmap --stream-count=3; done
Eventually this either causes the system lockup or EOF timeouts at all
subsequent stream on, until a system reset.
The lockup occurs when disabling the IDMA channel at stream off. Disabling
the CSI before disabling the IDMA channel appears to be a reliable fix for
the hard lockup.

commit a19c22677377b87e4354f7306f46ad99bc982a9f upstream.
Upstream must be stopped immediately after receiving the last EOF and
before disabling the IDMA channel. This can be accomplished by moving
upstream stream off to just after receiving the last EOF completion in
prp_stop(). For symmetry also move upstream stream on to end of
prp_start().
This fixes a complete system hard lockup on the SabreAuto when streaming
from the ADV7180, by repeatedly sending a stream off immediately followed
by stream on:
while true; do v4l2-ctl -d1 --stream-mmap --stream-count=3; done
Eventually this either causes the system lockup or EOF timeouts at all
subsequent stream on, until a system reset.
The lockup occurs when disabling the IDMA channel at stream off. Stopping
the video data stream entering the IDMA channel before disabling the
channel itself appears to be a reliable fix for the hard lockup.

Including asm/cacheflush.h first results in the following build error
when trying to build sparc32:allmodconfig, because 'struct page' has not
been declared, and the function declaration ends up creating a separate
(private) declaration of struct page (as a result of function arguments
being in the scope of the function declaration and definition, not in
global scope).
The C scoping rules do not just affect variable visibility, they also
affect type declaration visibility.
The end result is that when the actual call site is seen in
<linux/highmem.h>, the 'struct page' type in the caller is not the same
'struct page' that the function was declared with, resulting in:
In file included from arch/sparc/include/asm/page.h:10:0,

The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:
vmalloc(a * b)
with:
vmalloc(array_size(a, b))
as well as handling cases of:
vmalloc(a * b * c)
with:
vmalloc(array3_size(a, b, c))
This does, however, attempt to ignore constant size factors like:
vmalloc(4 * 1024)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:
kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)
as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().
The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

Pull media updates from Mauro Carvalho Chehab:
- remove of atomisp driver from staging, as nobody would have time to
dedicate huge efforts to fix all the problems there. Also, we have a
feeling that the driver may not even run the way it is.
- move Zoran driver to staging, in order to be either fixed to use VB2
and the proper media kAPIs or to be removed
- remove videobuf-dvb driver, with is unused for a while
- some V4L2 documentation fixes/improvements
- new sensor drivers: imx258 and ov7251
- a new driver was added to allow using I2C transparent drivers
- several improvements at the ddbridge driver
- several improvements at the ISDB pt1 driver, making it more coherent
with the DVB framework
- added a new platform driver for MIPI CSI-2 RX: cadence
- now, all media drivers can be compiled on x86 with COMPILE_TEST
- almost all media drivers now build on non-x86 architectures with
COMPILE_TEST
- lots of other random stuff: cleanups, support for new board models,
bug fixes, etc

A failed memory client reset doesn't prevent VDE from resetting, hence

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.
Note:
- The various VIDEOBUF*DMA* symbols had to loose their dependencies on
HAS_DMA, as they are selected by several individual drivers.

This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.
So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.

The atomisp driver has a long list of todo items and little has been done
to address these lately while more has been added. The driver is also not
functional. In other words, the driver would not be getting out of staging
in the foreseeable future. At the same time it consumes developer
resources in order to maintain the flaky code base. Remove it.

When atomisp got merged, there were so many warnings with W=1
that we simply disabled the ones that were causing troubles.
Since then, several changes got applied to atomisp, and the
number of warnings are a way smaller than it used to be.
So, let's reenable warnings there and fix the issues.

Since commit 50b0f0aee839 ("gpu: ipu-csi: add 10/12-bit grayscale
support to mbus_code_to_bus_cfg") the IPU CSI can be configured to
capture 10-bit and 12-bit grayscale formats, expanded to 16-bit
grayscale, in bayer/generic data mode.
This patch adds support for V4L2_PIX_FMT_Y16 captured from sensors
that provide MEDIA_BUS_FMT_Y10_1X10 or MEDIA_BUS_FMT_Y12_1X12 data.

This is Open Firmware driver, hence 'of_device.h' should be included
instead of 'platform_device.h'. Right now OF headers happen to be included

I've noticed that decoding fails sometime if size of bitstream buffer
isn't aligned to 16K, probably because HW fetches data from memory in
a 16K granularity and if the last chunk of data isn't aligned, HW reads
garbage data beyond the dmabuf and tries to parse it.

drivers/staging/media/atomisp/pci/atomisp2/hmm/hmm_bo.c:324 __bo_take_off_handling() error: we previously assumed 'bo->prev' could be null (see line 314)
Because it can't properly analize the truth table for the above

There are two functions used externally:
drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:866:6: warning: symbol 'atomisp_do_compat_ioctl' was not declared. Should it be static?
drivers/staging/media/atomisp/pci/atomisp2/atomisp_compat_ioctl32.c:1110:6: warning: symbol 'atomisp_compat_ioctl32' was not declared. Should it be static?
whose include header is missing. Add it.

The logic at get_atomisp_parameters32() is broken, as pointed by

It tries to access userspace data directly, without calling
get_user(). That should generate OOPS. Thankfully, the right
logic is already there (although commented out).

Changeset dc9f65cf9aea ("media: staging: atomisp: avoid a warning if 32
bits build") was meant to solve an impossible condition when building
with 32 bits. It turns that this impossible condition also happens wit
64 bits:
drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:698 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u64max > u64max)'
After a further analysis, this condition will always be false as, on
all architectures, size_t doesn't have more bits than unsigned long.
Also, the only two archs that really matter are x86 and x86_64, as this
driver doesn't build on other archs (as it depends on X86-specific UEFI
support).
So, just drop the useless code.
Fixes: dc9f65cf9aea ("media: staging: atomisp: avoid a warning if 32 bits build")

it makes no sense to use strncmp() with a size with is
bigger than the string we're comparing with.
Fix those warnings:
drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c:776 atomisp_open() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 32)
drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c:913 atomisp_release() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 32)
drivers/staging/media/atomisp/pci/atomisp2/atomisp_ioctl.c:2751 atomisp_vidioc_default() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 32)
