Alexandre Courbot 2abb4db289 media: mtk-vcodec: vdec: set VPI IPI handler in one place
Each of the supported decoder formats used to set the same RPC
interrupt handler by themselves, even though this could be done
by the IF init function itself. Move it to the right place and stop
making its symbol public.

Yunfei Dong dda8415e17 media: mtk-vcodec: vdec: fix incorrect pointer dereference
mtk_q_data::fmt is actually a pointer and must be dereferenced as such.
This went under the radar because mtk_v4l2_debug() evaluates to nothing
unless DEBUG is defined.

Christophe JAILLET a9cc4cbcdf media: seco-cec: Add a missing 'release_region()' in an error handling path
At the beginning of the probe function, we have a call to
'request_muxed_region(BRA_SMB_BASE_ADDR, 7, "CEC00001")()'

A corresponding 'release_region()' is performed in the remove function but
is lacking in the error handling path.

Add it.

Benoit Parrot ea169d2d65 media: am437x-vpfe: Remove per bus width static data
The bus related static data included in the vpfe_fmt
static table can be derived dynamically instead.
This simplify the table and it's use.

We instead replace the per bus data info with just
the usual bit per pixel value for each supported
pixel format.

Benoit Parrot 750ef54b7e media: am437x-vpfe: TRY_FMT ioctl is not really trying anything
The try_fmt was not actually trying out the provided format
but merely returning the current format basically like get_fmt.
In addition set_fmt should first invoked try_fmt to validate the
given format before applying it to the hardware.

To fix all of these the whole get/try/set ioctl functions had to
be reworked.
When calculating the bytesperline/stride and sizeimage format
member we don't need to locally store the current value of
bytesperpixel as it can easily get derived dynamically.

Benoit Parrot b58e69e9a5 media: am437x-vpfe: Wait for end of frame before tear-down
We were originally attempting to stop all processing as soon
as possible, but the in-progress DMA operation cannot be canceled.
This led to the module being in a busy state and prevented proper
power management functionality.

The existing implementation would attempt to clean things up by waiting
up to 50ms. However when receiving video frame at 15fps or lower,
it meant an inter frame arrival rate of 66.6 ms or higher.
In such cases upon tear down the following message could be seen:
omap_hwmod: vpfe0: _wait_target_disable failed

This patch fixes this issue by adding a stopping state where
we would wait for the next Vsync before disabling the hardware.

Shuah Khan d7fb5c361c media: vimc: Fix gpf in rmmod path when stream is active
If vimc module is removed while streaming is in progress, sensor subdev
unregister runs into general protection fault when it tries to unregister
media entities. This is a common subdev problem related to releasing
pads from v4l2_device_unregister_subdev() before calling unregister.
Unregister references pads during unregistering subdev.

The sd release handler is the right place for releasing all sd resources
including pads. The release handlers currently release all resources
except the pads.

Fix v4l2_device_unregister_subdev() not release pads and release pads
from the sd_int_op release handlers.

Shuah Khan f13d5f3619 media: vimc: Collapse component structure into a single monolithic driver
vimc uses Component API to split the driver into functional components.
The real hardware resembles a monolith structure than component and
component structure added a level of complexity making it hard to
maintain without adding any real benefit.

The sensor is one vimc component that would makes sense to be a separate
module to closely align with the real hardware. It would be easier to
collapse vimc into single monolithic driver first and then split the
sensor off as a separate module.

Collapse it into a single monolithic driver removing the Component API.
This patch removes the component API and makes minimal changes to the
code base preserving the functional division of the code structure.
Preserving the functional structure allows us to split the sensor off
as a separate module in the future.

Major design elements in this change are:
- Use existing struct vimc_ent_config and struct vimc_pipeline_config
  to drive the initialization of the functional components.
- Make vimc_device and vimc_ent_config global by moving them to
  vimc-common.h
- Add two new hooks add and rm to initialize and register, unregister
  and free subdevs.
- All component API is now gone and bind and unbind hooks are modified
  to do "add" and "rm" with minimal changes to just add and rm subdevs.
- vimc-core's bind and unbind are now register and unregister.
- Add a new field to vimc_device structure for saving the pointers to
  struct vimc_ent_device(s) subdevs create in their "add" hooks. These
  get used to create links and removing the subdevs. vimc-core allocates
  this array which sized to number of entries in the topology defined in
  the vimc_pipeline_config structure.
- vimc-core invokes "add" hooks from its vimc_register_devices().
  The "add" hooks remain the same and register subdevs. They don't
  create platform devices of their own and use vimc's pdev.dev as
  their reference device. Each "add" hook returns pointer to its struct
  vimc_ent_device. This is saved in the vimc_device ent_devs array.
- vimc-core invokes "rm" hooks from its unregister to unregister subdevs
  and cleanup.
- vimc-core invokes "add" and "rm" hooks with pointer to struct vimc_device
  and the corresponding vimc_ent_device saved in the ent_devs.

The following configure and stream test works on all devices.

media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'

Enric Balletbo i Serra 840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

Mauro Carvalho Chehab 95c520690f media: don't do a 31 bit shift on a signed int
On 32-bits archs, a signed integer has 31 bits plus on extra
bit for signal. Due to that, touching the 32th bit with something
like:

	int bar = 1 << 31;

has an undefined behavior in C on 32 bit architectures, as it
touches the signal bit. This is warned by cppcheck.

Instead, force the numbers to be unsigned, in order to solve this
issue.

As warned by cppcheck:

	[drivers/media/dvb-frontends/cx24123.c:434]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour
	[drivers/media/pci/bt8xx/bttv-input.c:87]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour
	[drivers/media/pci/bt8xx/bttv-input.c:98]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour
			...
	[drivers/media/v4l2-core/v4l2-ioctl.c:1391]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour

There are lots of places where we're doing 1 << 31. That's bad,
as, depending on the architecture, this has an undefined behavior.

The BIT() macro is already prepared to handle this, so, let's
just switch all "1 << number" macros by BIT(number) at the header files
with has 1 << 31.

In case of sensor malfunction, stop streaming timeout takes much longer
than expected. This is due to conversion of time to jiffies: milliseconds
multiplied with HZ (ticks/second) gives out a value of jiffies with 10^3
greater. We need to also divide by 10^3 to obtain the right jiffies value.
In other words FRAME_INTERVAL_MILLI_SEC must be in seconds in order to
multiply by HZ and get the right jiffies value to add to the current
jiffies for the timeout expire time.

Geert Uytterhoeven 4fd2293856 media: fdp1: Reduce FCP not found message level to debug
When support for the IPMMU is not enabled, the FDP driver may be
probe-deferred multiple times, causing several messages to be printed
like:

    rcar_fdp1 fe940000.fdp1: FCP not found (-517)
    rcar_fdp1 fe944000.fdp1: FCP not found (-517)

Fix this by reducing the message level to debug level, as is done in the
VSP1 driver.

Helen Koike 09c41a23a2 media: Revert "media: vimc: propagate pixel format in the stream"
This reverts commit b6c61a6c37.

The requested pixelformat is being propagated from the capture to the
tpg in the sensor.

This was a bad design choice, as we start having the following issues:

* We set a pixelformat in the capture;
* We set matching media bus formats in the subdevices pads;
* Link validate looks fine (sizes matches, media bus formats matches);
* Issue: if some of the subdevice doesn't know how to generate the
requested pixelformat in the capture, then stream_on fails. This is bad
because capture says it supports that pixelformat, everything looks
fine, but it is not, and there is no way to find it out through the
links.

This patch was implemented so we could request any pixelformat from the
pipeline regardeless of the media bus format configured between pads.
Not all pixelformat can be mapped into a media bus code (e.g.
multiplanar formats), so with this patch we could request those
pixelformats from the tpg.

Solution: map pixelformats to media bus codes as before, and implement
conversions to other pixelformats in the capture to support multiplanar.

So first step to this solution is to revert this patch.

- Empty bus_info in QUERYCAP.
- Overlay format handling wasn't zeroing bitmap/clips and
  didn't return the chromakey correctly.
- G_FBUF didn't fill in many of the v4l2_framebuffer values.
  Now also return the base address of the corresponding
  framebuffer that this overlays.

Hans Verkuil d555c34338 omap-dma/omap_vout_vrfb: fix off-by-one fi value
The OMAP 4 TRM specifies that when using double-index addressing
the address increases by the ES plus the EI value minus 1 within
a frame. When a full frame is transferred, the address increases
by the ES plus the frame index (FI) value minus 1.

The omap-dma code didn't account for the 'minus 1' in the FI register.
To get correct addressing, add 1 to the src_icg value.

This was found when testing a hacked version of the media m2m-deinterlace.c
driver on a Pandaboard.

The only other source that uses this feature is omap_vout_vrfb.c,
and that adds a + 1 when setting the dst_icg. This is a workaround
for the broken omap-dma.c behavior. So remove the workaround at the
same time that we fix omap-dma.c.

I tested the omap_vout driver with a Beagle XM board to check that
the '+ 1' in omap_vout_vrfb.c was indeed a workaround for the omap-dma
bug.

Rework OF endpoint parsing for the omap3isp driver. This does add some
lines of code. The benefits are still clear:

- the great complication related to callbacks in endpoint parsing is gone;
  instead endpoints are obtained port by port and

- endpoints may now have a default bus configuration which was not
  possible while using callbacks. This driver does not benefit from that
  feature, but as the omap3isp is one of the exemplary drivers, this works
  as an example for driver developers.

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.

As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.

Luckily, perhaps, there were just a handful of callers using the function.

Guillaume Tucker 79e85d1d2c media: vivid: fix device init when no_error_inj=1 and fb disabled
Add an extra condition to add the video output control class when the
device has some hdmi outputs defined.  This is required to then always
be able to add the display present control, which is enabled when
there are some hdmi outputs.

This fixes the corner case where no_error_inj is enabled and the
device has no frame buffer but some hdmi outputs, as otherwise the
video output control class would be added anyway.  Without this fix,
the sanity checks fail in v4l2_ctrl_new() as name is NULL.

Arnd Bergmann 1a03f91c2c media: vivid: work around high stack usage with clang
Building a KASAN-enabled kernel with clang ends up in a case where too
much is inlined into vivid_thread_vid_cap() and the stack usage grows
a lot, possibly when the register allocation fails to produce efficient
code and spills a lot of temporaries to the stack. This uses more
than twice the amount of stack than the sum of the individual functions
when they are not inlined:

drivers/media/platform/vivid/vivid-kthread-cap.c:766:12: error: stack frame size of 2208 bytes in function 'vivid_thread_vid_cap' [-Werror,-Wframe-larger-than=]

Marking two of the key functions in here as 'noinline_for_stack' avoids
the pathological case in clang without any apparent downside for gcc.

Colin Ian King b98fd3cb6d media: vivid: fix potential integer overflow on left shift
There is a potential integer overflow when int 2 is left shifted
as this is evaluated using 32 bit arithmetic but is being used in
a context that expects an expression of type s64.  Fix this by

Hans Verkuil b61789f53d media: drivers/media: don't set pix->priv = 0
The priv field of struct v4l2_pix_format shouldn't be set by drivers,
it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC.

Drop this from the few media drivers that still do this.

Note that the gspca patch is slightly more involved since some of the
sub-gspca drivers use the priv field internally.

Dariusz Marcinkiewicz 32a847f9fa media: cec: add struct cec_connector_info support
Define struct cec_connector_info in media/cec.h and define
CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to
uapi/linux/cec.h.

The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but
cec_allocate_adapter() will remove it again until the public API
for this can be enabled once all drm drivers wire this up correctly.

Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions,
which are needed by drm drivers to fill in the cec_connector info
based on a drm_connector.

The cec_notifier_(un)register and cec_register_cec_notifier
prototypes were moved from cec-notifier.h to cec.h since cec.h no longer
includes cec-notifier.h. These headers included each other before,
which caused various problems.

Due to these changes the seco-cec driver was changed as well: it
should include cec-notifier.h, not cec.h.
