The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.

This patch enables decoding of h.264 and mpeg4 streams on CODA7541.
Queued output buffers are immediately copied into the bitstream
ringbuffer. A device_run can be scheduled whenever there is either
enough compressed bitstream data, or the CODA is in stream end mode.
Each successful device_run, data is read from the bitstream ringbuffer
and a frame is decoded into a free internal framebuffer. Depending on
reordering, a possibly previously decoded frame is marked as display
frame, and at the same time the display frame from the previous run
is copied out into a capture buffer by the rotator hardware.
The dequeued capture buffers are counted to send the EOS signal to
userspace with the last frame. When userspace sends the decoder stop
command or enqueues an empty output buffer, the stream end flag is
set to allow decoding the remaining frames in the bitstream
ringbuffer.
The enum_fmt/try_fmt functions return fixed capture buffer sizes
while the output queue is streaming, to allow better autonegotiation
in userspace.
A per-context buffer mutex is used to lock the picture run against
buffer dequeueing: if a job gets queued, then streamoff dequeues
the last buffer, and then device_run is called, bail out. For that
the interrupt handler has to be threaded.

Commit 1c1d86a1ea ("[media] v4l2: always require v4l2_dev,

It converted most of the drivers using the parent field of video_device
to v4l2_dev field. G2D driver did not set the parent field. Hence it got
left out. Without this patch we get the following boot warning and G2D
driver fails to register the video device.

These changes are all to SoC-specific code, a total of 33 branches on
17 platforms were pulled into this. Like last time, Renesas sh-mobile
is now the platform with the most changes, followed by OMAP and EXYNOS.
Two new platforms, TI Keystone and Rockchips RK3xxx are added in
this branch, both containing almost no platform specific code at all,
since they are using generic subsystem interfaces for clocks, pinctrl,
interrupts etc. The device drivers are getting merged through the
respective subsystem maintainer trees.
One more SoC (u300) is now multiplatform capable and several others
(shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
towards that goal with this series but need more work.
Also noteworthy is the work on PCI here, which is traditionally part of
the SoC specific code. With the changes done by Thomas Petazzoni, we can
now more easily have PCI host controller drivers as loadable modules and
keep them separate from the platform code in drivers/pci/host. This has
already led to the discovery that three platforms (exynos, spear and imx)
are actually using an identical PCIe host controller and will be able
to share a driver once support for spear and imx is added.
Conflicts:
* asm/glue-proc.h has one CPU type getting added that conflicts
with another addition in 3.10-rc7
* Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

This patch changes the firmware file names of the FIMC-IS subsystem.
It is needed since there are different firmwares used across various
SoC series, e.g. Exynos4 and Exynos5.
Also the sensor specific "setfile" name is changed, to account for
it depends on an image sensor and is also specific to the FIMC-IS
and the SoC.
This is a change for a driver merged in 3.10.

Add compatible property for the Exynos5250 and enable the frame start
and frame end interrupts. These interrupts are needed for the Exynos5
FIMC-IS firmware. The driver enables those interrupt only where available,
depending on the 'compatible' property. This can be optimized further,
by exposing some API at the subdev driver, so the host driver can enable
extra interrupts only for the image processing chains involving FIMC-IS.

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE
IP. A 'compatible' string is added for Exynos5250 compatible devices
and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ
register, masking output DMA buffer address slots. The frame interrupt
is enabled so there are now 2 interrupts per frame. This likely can be
optimized in future by using any status registers that allow to figure
out what the last and the currently written frame buffer is. It would
also be more reliable in cases where there are high interrupt service
latencies.

The current Makefile rules to build font support are messy and buggy.
Replace them by Kconfig rules:
- Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
code,
- Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
- Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
font,
- Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
- Always process drivers/video/console/Makefile, as some drivers need
fonts even if CONFIG_VT is not set.
This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
drivers):

The parent field will eventually disappear to be replaced by v4l2_dev.
soc_camera does provide a v4l2_device struct but did not point to it in
struct video_device. This is now fixed.
Now the video nodes can be found under the correct platform bus, and
the advanced debug ioctls work correctly as well (the core implementation
of those ioctls requires that v4l2_dev is set correctly).

The ISP clock register content is not preserved over the ISP power domain
off/on cycle. Instead of setting the clock frequencies once at probe time
the clock rates set up is moved to the runtime_resume handler, which is
invoked after the related power domain is already enabled, ensuring the
clocks are properly configured when the device is actively used.
This fixes the FIMC-IS malfunctions and STREAM ON timeout errors accuring

This patch corrects the link_notify handler to support more complex
pipelines, including fimc-lite and fimc-is entities.
After the FIMC-IS driver addition the assumptions made in the link_notify
callback are no longer valid, e.g. the link between fimc-lite subdev and
its video node is not immutable any more and there is more subdevs than
just sensor, MIPI-CSIS and FIMC(-LITE).
The graph is now walked and for each video node found a media pipeline
which ends at this node is disabled/enabled (the subdevs are powered
on/off).

Currently the media device link_notify callback is invoked before the
actual change of state of a link when the link is being enabled, and
after the actual change of state when the link is being disabled.
This doesn't allow a media device driver to perform any operations
on a full graph before a link is disabled, as well as performing
any tasks on a modified graph right after a link's state is changed.
This patch modifies signature of the link_notify callback. This
callback is now called always before and after a link's state change.
To distinguish the notifications a 'notification' argument is added
to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates
notification before link's state change and
MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after
link flags change.

This patch moves the code for inheriting subdev v4l2 controls on the
FIMC video capture nodes from open()/close() fops to the link setup
notification callback. This allows for the state of the FIMC controls
to be always kept, in opposite to the current situation when it is
lost when last process closes video device.
There is no visible change for the original V4L2 compliant interface.
For the MC aware applications (user_subdev_api == true) inheriting
of the controls is dropped, since there can be same controls on the
subdevs withing single pipeline, now when the ISP (FIMC-IS) is also
used.
This patch is a prerequisite to allow /dev/video device to be opened
without errors even if there is no media links connecting it to an
image source (sensor) subdev. This is required for a libv4l2 plugin
to be initialized while a video node is opened and it also should be
possible to always open the device to query the capabilities.

that this clock is always on, left in its default state after system
reset.
Remove handling of this clock from the FIMC-IS driver to avoid breaking
other subsystems.

Use clk_prepare_enable/clk_unprepare_disable instead of preparing the
clocks during the driver initalization and then using just clk_disable/
clk_enable. The clock framework doesn't guarantee a clock will not get
enabled during e.g. clk_set_parent if clk_prepare has been called on it.
So we ensure clk_prepare() is called only when it is safe to enable
the clocks, i.e. the parent clocks and the clocks' frequencies are set.
It must be ensured the FIMC-IS clocks have proper frequencies before they
are enabled, otherwise the whole system will hang.

Not only do we need to wait for job completion when we want to
call a command on the CODA in start/stop_streaming, we also need
to make sure that a new job doesn't start before the command
finished.
Use a mutex to lock the coda command handling. On timeout, the
device_run job must be marked as finished and the mutex released,
as otherwise coda_release will block.

This patch adds a list of supported codecs per device type which is used to
determine the allowed pixel formats and maximum frame sizes depending on the
possible codecs. It allows frame sizes larger than 720 x 576 on CODA7 and adds
support for the YVU420 (planar YUV 4:2:0 with switched Cb and Cr) format.
Other uncompressed formats that could be added in the future are the chroma
interleaved NV12 and NV21 formats and the multiplanar variants YUV420M,
YVU420M, NV12M, and NV21M.
Further, rawstreamon is renamed to streamon_out and compstreamon is renamed
to streamon_cap in preparation for decoding support. The maximum encoded
frame buffer size is increased to 1 MiB.
Instead of tracking inst_type and codec across S_FMT calls, set the codec
and inst_type in start_streaming.

MFC uses two clocks - MFC gate clock and special clock
which is named as "sclk_mfc" in exynos4 and "aclk_333" in
exynos5 SoC. The driver was doing just a clk_prepare on
this special clock without a clk_enable call. As this
sclk is the parent of gate clock, it gets prepared and
enabled along with the gate clock. So there is no need
for the driver to use this sclk. This patch removes the
sclk usage from driver.

When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.
To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

Originally struct v4l2_capability driver and card name was filled
with name of the platform device. After switching to the device tree
the device names have changed and now are 4 different driver names
reported, depending on the video device opened. So instead of e.g.
"exynos4-fimc" there is now one of: 11800000.fimc, 11810000.fimc,
11820000.fimc, 11830000.fimc.
Fix this by using dev->driver_name, rather than platform device name.
A common vidioc_querycap function is created for both M2M and capture
video node.
This fixes any breakage at user space should any application/library
rely on the driver's name.

By default the VPSS clocks were enabled in capture driver
for davinci family which creates duplicates for dm355/dm365/dm644x.
This patch adds support to enable the VPSS clocks in VPSS driver,
which avoids duplication of code and also adding clock aliases.
This patch uses PM runtime API to enable/disable clock, instead
of DaVinci clock framework. con_ids for master and slave clocks of
vpss is added in pm_domain.
This patch cleanups the VPSS clock enabling in the capture driver,
and also removes the clock alias in machine file. Along side adds
a vpss slave clock for DM365 as mentioned by Sekhar
(https://patchwork.kernel.org/patch/1221261/).
The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock
is now implemented as part of the VPSS driver.

drivers/media/platform/davinci/Kconfig uses selects where
it should be using 'depends on'. This results in warnings of
the following sort when doing randconfig builds.
warning: (VIDEO_DM6446_CCDC && VIDEO_DM355_CCDC && VIDEO_ISIF && VIDEO_DAVINCI_VPBE_DISPLAY) selects VIDEO_VPSS_SYSTEM which has unmet direct dependencies (MEDIA_SUPPORT && V4L_PLATFORM_DRIVERS && ARCH_DAVINCI)
The VPIF kconfigs had a strange 'select' and 'depends on' cross
linkage which have been fixed as well by removing unneeded
VIDEO_DAVINCI_VPIF config symbol.
Similarly, remove the unnecessary VIDEO_VPSS_SYSTEM and
VIDEO_VPFE_CAPTURE. They don't select any independent functionality
and were being used to manage code dependencies which can
be handled using makefile.
Selecting video modules is now dependent on all ARCH_DAVINCI
instead of specific EVMs and SoCs earlier. This should help build
coverage. Remove unnecessary 'default y' for some config symbols.
While at it, fix the Kconfig help text to make it more readable
and fix names of modules created during module build.
Rename VIDEO_ISIF to VIDEO_DM365_ISIF as per suggestion from
Prabhakar.
This patch has only been build tested; I have tried to not break
any existing assumptions. I do not have the setup to test video,
so any test reports welcome.

This patch adds the ISP I2C bus controller driver files.
Creating a standard I2C bus adapter, even if the driver doesn't
actually communicate with the hardware and it is instead
controlled by the ISP firmware running on the Cortex-A5, allows
to use standard hardware description in the device tree. As the
sensor would have actually had a standard V4L2 sub-device driver
run on the host CPU.
This approach allows to adapt the driver with a relatively small
effort should the Imaging Subsystem architecture change so that
the I2C bus is handled by the host's CPU OS, rather than the
internal FIMC-IS ARM CPU firmware. The image sensor driver could
be a standard I2C client driver, as in case of most existing
image sensors.

This patch adds a set of core files of the Exynos4x12 FIMC-IS
V4L2 driver. This includes main functionality like allocating

host CPU <-> IS command and error code definitions.
The driver currently exposes a single subdev named FIMC-IS-ISP,
which corresponds to the FIMC-IS ISP and DRC IP blocks.
The FIMC-IS-ISP subdev currently supports only a subset of user
controls. For other controls we need several extensions at the
V4L2 API. The supported standard controls are:
brightness, contrast, saturation, hue, sharpness, 3a_lock,
exposure_time_absolute, white_balance_auto_preset,
iso_sensitivity, iso_sensitivity_auto, exposure_metering_mode.

The s5p-fimc directory now contains drivers for multiple IP blocks
found in multiple Samsung application processors. This includes FIMC
(CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver
is going to be put into same directory. Hence we rename it to
exynos4-is as s5p-fimc was only relevant for early version of this
driver, when it only supported FIMC IP block.
The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will
be included in drivers/media/platform/exynos4-is directory, with some
modules shared with exynos5 series, while the rest of exynos5 specific
modules will find their home in drivers/media/platform/exynos5-is.

Since the FIMC-IS firmware communicates with an image sensor directly
through the ISP I2C bus controllers the sub-devices power supplies
cannot be simply enabled from left to right or disabled from right
to left along the processing pipeline. Thus a subdev index to call
s_power() on is looked up from a table, rather than doing the op call
based on increasing/decreasing indexes.

In configurations where FIMC-LITE is used to capture image signal
from an external sensor only we need to ensure one of FIMC devices
is in active power state and the "fimc" gate clock is enabled.
Otherwise the CAMCLK clock output signal will be masked off
preventing an external sensor's operation.
This affect processing pipelines like:
- sensor -> FIMC-LITE -> memory
- sensor -> MIPI-CSIS -> FIMC-LITE -> memory

A second sink pad is added to each FIMC.N subdev that will be used
to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30
format is supported at this pad (FIMC_SD_PAD_SINK_FIFO).
The routine checking for mismatch in the image formats at sides of
the links is updated to account for the fact FIMC.X subdevs now have
sink pads at the pad indexes 0, 1 and source pad at pad index 2.
If link to FIMC.X pad 1 is activated we switch FIMC input data bus
type to the ISP Writeback. Only a single active link to FIMC.X pad 0
or 1 will be allowed at any time.

The sensor (I2C and/or SPI client) devices are instantiated by their
corresponding control bus drivers. Since the I2C client's master clock
is often provided by a video bus receiver (host interface) or other
than I2C/SPI controller device, the drivers of those client devices
are not accessing hardware in their driver's probe() callback. Instead,
after enabling clock, the host driver calls back into a sub-device
when it wants to activate them. This pattern is used by some in-tree
drivers and this patch also uses it for DT case. This patch is intended
as a first step for adding device tree support to the S5P/Exynos SoC
camera drivers. The second one is adding support for asynchronous
sub-devices registration and clock control from sub-device driver
level. The bindings shall not change when asynchronous probing support
is added.

I've chosen not to follow the suggestions in that thread since gamma_width is
really a different property from data_size. What you really want is to know if
gamma_width fits inside data_size and for that you need to translate each

Converting more ARM platforms to multiplatform support. This time, OMAP
gets converted, which is a major step since this is by far the largest
platform in terms of code size. The same thing happens to the vt8500
platform.
Conflicts include:
* Two mach/uncompress.h files are removed, the changes made to them
elsewhere can be discarded now.
* Moving the OMAP4 irq_match array has context clashes with turning
omap4_sar_ram_init into an omap_early_initcall()

Merge branch 'omap/multiplatform-fixes', tag 'v3.8-rc5' into next/multiplatform
The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.
There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous
#include that was causing build errors.

It is now possible to build the davinci vpss code
on multiplatform kernels, which causes a problem
since the driver tries to incude the davinci

that file is not required at all in the driver,
so we can simply remove the #include statement.

fimc[] array is erroneously accessed instead of fimc_lite[] and

Newer Exynos4 SoC are equipped with a local camera ISP that
controls external raw image sensor directly. Such sensors
can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to
the ISP, which then feeds image data to the FIMCn IP. Thus
there can be two busses associated with an image source
(sensor). Rename struct s5p_fimc_isp_info describing external
image sensor (video decoder) to struct fimc_source_info to
avoid confusion. bus_type is split into fimc_bus_type and
sensor_bus_type. The bus type enumeration is extended to
include both FIMC Writeback input types.
The bus_type enumeration and the data structure name in the
board files are modified according to the above changes.

The previous method of registering platform entities into the main
driver using driver_find() and then iterating over devices bound to
a driver was racy and is being removed here. Nothing was preventing
module from unloading during a call to try_module_get(driver->owner).
Instead, we look up a device first and then check for its driver while
holding device lock.
The platform sub-devices are looked up and registered to the top
level driver. When any sub-device is not yet initialized and ready
the main driver's probe() will be deferred.

This patch fixes regression introduced in commit 6319d6a002beb26631
'[media] fimc-lite: Add ISP FIFO output support'.
In case of a configuration where video is captured at the video node
exposed by the FIMC-LITE driver there is a following video pipeline:
sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node
In this situation s_stream() handler of the FIMC-LITE.n is called
back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video
node, through vb2_stream_on/off(), start/stop_streaming and
fimc_pipeline_call(set_stream). The fimc->lock mutex is already held
then, before invoking vidioc_streamon/off. So it must not be taken
again in the s_stream() callback in this case, to avoid a deadlock.
This patch makes fimc->out_path atomic_t so the mutex don't need
to be taken in the FIMC-LITE subdev s_stream() callback in the DMA
output case.

Modified the G2D driver (which initially supported only H/W Rev.3)
to support H/W Rev.4.1 present on Exynos4x12 and Exynos52x0 SOCs.
- Set the SRC and DST type to 'memory' instead of using reset values.
- FIMG2D v4.1 H/W uses different logic for stretching(scaling).
- Use CACHECTL_REG only with FIMG2D v3.

Make sure bytesperline for Cb, Cr planes for V4L2_PIX_FMT_YUV420M
format is half of the Y plane value, rather than having same
bytesperline for all planes.
While at it, simplify the bytesperline parameter handling by
storing it when image format is set and returning those values
when getting the format, instead of recalculating bytesperline
from intermediate parameters.

This patch fixes a bug which causes all histogram regions to start in the
top left corner of the image. The histogram region coordinates are 16 bit
values which share a 32 bit register. The bug is due to the region end
value assignments overwriting the region start values with zero.

The preview engine includes filters that consume columns and lines as
part of their operation, thus resulting in a cropped image. To allow
turning those filters on/off during streaming without affecting the
output image size, the driver adds additional cropping to make the total
number of cropped columns and lines constant regardless of which filters
are enabled.
This process needlessly includes the CFA filter, as whether the filter
is enabled only depends on the sink pad format, which can't change
during streaming.
Exclude the CFA filter from the preview engine margins.

Walking rbtree while it's modified is a Bad Idea(tm); besides,
the result of find_vma() can be freed just as it's getting returned
to caller. Fortunately, it's easy to fix - just take ->mmap_sem a bit
earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET -
in that case we don't even look at its result).
While we are at it, what prevents VIDIOC_PREPARE_BUF calling
v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() ->
__buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(),
AFAICS without having taken ->mmap_sem anywhere in process? The code flow
is bloody convoluted and depends on a bunch of things done by initialization,
so I certainly might've missed something...

This patch patch eliminates potential AB-BA deadlock when one process calls
open(), or VIDIOC_S/TRY_FMT ioctl on the FIMC capture video node, while
other thread is reconfiguring media links via media device node:
/dev/video? open() /dev/media? MEDIA_IOC_SETUP_LINK ioctl
mutex_lock(video_lock) mutex_lock(graph_lock)
fimc_pipeline_open() fimc_md_link_notify()
mutex_lock(graph_lock) mutex_lock(video_lock)
... ...
The deadlock is avoided by always taking the graph mutex first in video
node open() or an ioctl, before the video lock is acquired. Reversed
order seems impossible, since media device driver's link_notify callback
is called with media graph mutex already held.
To ensure proper locking order VIDIOC_S_FMT and VIDIOC_TRY_FMT ioctls are
not serialized in the v4l2-core and the driver takes care of it itself.

struct soc_camera_link currently contains fields, used both by sensor and

host and a subdevice parts.

Currently soc-camera has a per-device node lock, used for video operations
and a per-host lock for code paths, modifying host's pipeline. Manipulating
the two locks increases complexity and doesn't bring any advantages. This
patch removes the per-device lock and uses the per-host lock for all
operations.

Currently devm_regulator_bulk_get() is called by soc-camera during host
driver probing, but regulators are attached to the camera platform
device, that is staying, independent whether the host probed successfully
or not. This can lead to repeated regulator requesting, if the host
driver is re-probed. Move the call to platform device probing to avoid
this.

The recently introduced host_lock causes lockdep warnings, besides, list
enumeration in scan_add_host() must be protected by holdint the list_lock.
OTOH, holding .video_lock in soc_camera_open() isn't enough to protect
the host during its building of the pipeline, because .video_lock is per
soc-camera device. If, e.g. more than one sensor can be attached to a host
and the user tries to open both device nodes simultaneously, host's .add()
method can be called simultaneously for both sensors. Fix these problems
by holding list_lock instead of .host_lock in scan_add_host() and taking
it shortly at the beginning of soc_camera_open(), and using .host_lock to
protect host's .add() and .remove() operations only.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

I was testing my video-over-ethernet subsystem recently, and vivi
seemed to be perfect video source for testing when one don't have lots
of capture boards and cameras. Only its framerate was hardcoded to
NTSC's 30fps, while in my country we usually use PAL (25 fps) and I
needed that to precisely simulate bandwidth.
That's why here is this patch with ->enum_frameintervals() and
->{g,s}_parm() implemented as suggested by Hans Verkuil which passes
v4l2-compliance and manual testing through v4l2-ctl -P / -p <fps>.
Regarding newly introduced __get_format(u32 pixelformat) I decided not
to convert original get_format() to operate on fourcc codes, since >= 3
places in driver need to deal with v4l2_format and otherwise it won't be
handy.
