Ezequiel Garcia ddc5c1f799 media: rockchip/rga: Fix bad dma_free_attrs() parameter
In rga_remove(), dma_free_attrs is being passed the wrong
cpu address, which triggers an exception if the driver is
removed. Fix it.

Tested on a RK3399 platform, with a bind/unbind cycle.

Hans Verkuil 87e1a881e1 media: media.h: remove linux/version.h include
The media.h public header is one of only three public headers that include
linux/version.h. Drop it from media.h. It was only used for an obsolete
define.

It has to be added to media-device.c, since that source relied on media.h
to include it.

Nicolas Dufresne 43bd1dce39 media: vivid: Fix V4L2_FIELD_ALTERNATE new frame check
The vivid driver will overlay stream time on generated frames. Though,
in interlacing mode V4L2_FIELD_ALTERNATE, each field is separate and
must have the same time to ensure proper render. Though, this time was
only updated every 2 frames as the code was checking against the wrong
counter (frame counter rather then field counter).

Philipp Zabel 0dff710d1f media: coda: add SPS fixup code for frame sizes that are not multiples of 16
The CODA7541 firmware does not set the SPS frame cropping fields to
properly describe coded h.264 streams with frame sizes that are not a
multiple of the macroblock size.
This adds RBSP parsing code and a SPS fixup routine to manually replace
the cropping information in the headers produced by the firmware with
the correct values.

Philipp Zabel 7988b2532a media: coda: let CODA960 firmware set frame cropping in SPS header
When encoding h.264, if visible resolution is not aligned to macroblock
size, frame cropping has to be set in the SPS header to produce correct
streams. The CODA960 firmware can do this on its own if asked to.

Guennadi Liakhovetski e5225c820c media: uvcvideo: Send a control event when a Control Change interrupt arrives
UVC defines a method of handling asynchronous controls, which sends a
USB packet over the interrupt pipe. This patch implements support for
such packets by sending a control event to the user. Since this can
involve USB traffic and, therefore, scheduling, this has to be done
in a work queue.

Guennadi Liakhovetski 8e7a1dbc7b media: uvcvideo: Handle control pipe protocol STALLs
When a command ends up in a STALL on the control pipe, use the Request
Error Code control to provide a more precise error information to the
user. For example, if a camera is still busy processing a control,
when the same or an interrelated control set request arrives, the
camera can react with a STALL and then return the "Not ready" status
in response to a UVC_VC_REQUEST_ERROR_CODE_CONTROL command. With this
patch the user would then get an EBUSY error code instead of a
generic EPIPE.

then the first tuner is destroyed and kfrees it again. The property
should only be kfree'd if the tuner is PRIMARY_TS.

Brad Love a7853c257a media: em28xx: Fix dual transport stream operation
Addresses the following, which introduced a regression itself:

Commit 509f89652f ("media: em28xx: fix a regression with HVR-950")

The regression fix breaks dual transport stream support. Currently,
when a tuner starts streaming it sets alt mode on the USB interface.
The problem is, in a dual tuner model, both tuners share the same
USB interface, so when the second tuner becomes active and sets alt
mode on the interface it kills streaming on the other port.

This patch addresses the regression by only setting alt mode
on the USB interface during em28xx_start_streaming, if the
device is not a dual tuner model. This allows all older and
single tuner devices to explicitly set alt mode during stream
startup. Testers report both isoc and bulk DualHD models work
correctly with the alt mode set only once, in em28xx_dvb_init.

Stanimir Varbanov f012b23d64 media: venus: implementing multi-stream support
This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.

Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.

Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).

The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

Hans Verkuil d272bc92c4 media: rename MEDIA_ENT_F_DTV_DECODER to MEDIA_ENT_F_DV_DECODER
The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.

Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.

We keep an alias to avoid breaking userspace applications.

Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.

Randy Dunlap ac3167257b headers: separate linux/mod_devicetable.h from linux/platform_device.h
At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel.  It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.

   4146 #include <linux/platform_device.h>

After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.

    225 #include <linux/mod_devicetable.h>

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this control cannot be used for querying since
it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.

The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)

In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in

Jacopo Mondi 158e2a53fc media: rcar-vin: Cache the mbus configuration flags
Media bus configuration flags and media bus type were so far a property
of each VIN instance, as the subdevice they were connected to was
immutable during the whole system life time.

With the forth-coming introduction of parallel input devices support,
a VIN instance can have the subdevice it is connected to switched at
runtime, from a CSI-2 subdevice to a parallel one and viceversa, through
the modification of links between media entities in the media controller
graph. To avoid discarding the per-subdevice configuration flags retrieved by
v4l2_fwnode parsing facilities, cache them in the 'rvin_graph_entity'
member of each VIN instance, opportunely renamed to 'rvin_parallel_entity'.

Also modify the register configuration function to take mbus flags into
account when running on a bus type that supports them.

The media bus type currently in use will be updated in a follow-up patch
to the link state change notification function.

in mc-compliant code path, each VIN may register its own notifier if any
parallel subdevice is connected there.

To avoid registering a notifier twice (once for parallel subdev and one
for the CSI-2 subdevs) create a group notifier, shared by all the VIN
instances.

Ezequiel Garcia be2fff6563 media: add helpers for memory-to-memory media controller
A memory-to-memory pipeline device consists in three
entities: two DMA engine and one video processing entities.
The DMA engine entities are linked to a V4L interface.

This commit add a new v4l2_m2m_{un}register_media_controller
API to register this topology.

For instance, a typical mem2mem device topology would
look like this:

Device topology
- entity 1: source (1 pad, 1 link)
            type Node subtype V4L flags 0
	pad0: Source
		-> "proc":1 [ENABLED,IMMUTABLE]

- entity 3: proc (2 pads, 2 links)
            type Node subtype Unknown flags 0
	pad0: Source
		-> "sink":0 [ENABLED,IMMUTABLE]
	pad1: Sink
		<- "source":0 [ENABLED,IMMUTABLE]

- entity 6: sink (1 pad, 1 link)
            type Node subtype V4L flags 0
	pad0: Sink
		<- "proc":0 [ENABLED,IMMUTABLE]

Currently links between entities and an interface are just marked as

It might become possible that drivers can disable such links (if for some
reason the device node cannot be used), so we might need to add a new link
flag at some point to mark interface links that can be changed by the driver
but not by userspace.

Ezequiel Garcia b53e19e161 media: s5p-g2d: Implement wait_prepare and wait_finish
This driver is currently specifying a vb2_queue lock,
which means it straightforward to implement wait_prepare
and wait_finish.

Having these callbacks releases the queue lock while blocking,
which improves latency by allowing for example streamoff
or qbuf operations while waiting in dqbuf.

Ezequiel Garcia cd63c0288f media: sta2x11: Add video_device and vb2_queue locks
Currently, this driver does not serialize its video4linux
ioctls, which is a bug, as race conditions might appear.

In addition, video_device and vb2_queue locks are now both
mandatory. Add them, and implement wait_prepare and
wait_finish.

To stay on the safe side, this commit uses a single mutex
for both locks. Better latency can be obtained by separating
these if needed.

Luca Ceresoli 96a2c731a4 media: imx274: consolidate per-mode data in imx274_frmfmt
Data about the implemented readout modes is partially stored in
imx274_formats[], the rest is scattered in several arrays. The latter
are then accessed using the mode index, e.g.:

  min_frame_len[priv->mode_index]

Consolidate all these data in imx274_formats[], and store a pointer to
the selected mode (i.e. imx274_formats[priv->mode_index]) in the main
device struct. This way code to use these data becomes more readable,
e.g.:

  priv->mode->min_frame_len

This removes lots of scaffolding code and keeps data about each mode
in a unique place.

Also remove a parameter to imx274_mode_regs() that is now unused.

While this adds the mode pointer to the device struct, it does not
remove the mode_index from it because mode_index is still used in two
dev_dbg() calls.  This will be handled in a follow-up commit.

Luca Ceresoli 438ac1fd5e media: imx274: initialize format before v4l2 controls
The current probe function calls v4l2_ctrl_handler_setup() before
initializing the format info. This triggers call paths such as:
imx274_probe -> v4l2_ctrl_handler_setup -> imx274_s_ctrl ->
imx274_set_exposure, where priv->mode_index is accessed before being
assigned.

This is wrong but does not trigger a visible bug because priv is
zero-initialized and 0 is the default value for priv->mode_index. But
this would become a crash in follow-up commits when mode_index is
replaced by a pointer that must always be valid.

Fix the bug before it shows up by initializing struct members early.

Add a v4l2 sub-device driver for the ak7375 lens voice coil.
This is a voice coil module using the i2c bus to control the
focus position.

ak7375 can write multiple bytes of data at a time. If more
data is received instead of the stop condition after receiving
one byte of data, the address inside the chip is automatically
incremented and the data is written into the next address.

The ak7375 can control the position with 12 bits value and
consists of two 8 bit registers show as below:
register 0x00(AK7375_REG_POSITION):
    +---+---+---+---+---+---+---+---+
    |D11|D10|D09|D08|D07|D06|D05|D04|
    +---+---+---+---+---+---+---+---+
register 0x01:
    +---+---+---+---+---+---+---+---+
    |D03|D02|D01|D00|---|---|---|---|
    +---+---+---+---+---+---+---+---+

This driver support :
    - set ak7375 to standby mode once suspend and
      turn it back to active if resume
    - set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl

The banding filter ON/OFF is controlled via bit 5 of COM8 register.  It
is attempted to be enabled in ov772x_set_params() by the following line.

	ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);

But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.

On the other hand, ov772x_s_ctrl() correctly sets the bit by:

	ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);

The same fix was already applied to non-soc_camera version of ov772x
driver in the commit commit a024ee14cd ("media: ov772x: correct setting

Javier Martinez Canillas 2ec7debd44 media: omap3isp: zero-initialize the isp cam_xclk{a,b} initial data
The struct clk_init_data init variable is declared in the isp_xclk_init()
function so is an automatic variable allocated in the stack. But it's not
explicitly zero-initialized, so some init fields are left uninitialized.

This causes the data structure to have undefined values that may confuse
the common clock framework when the clock is registered.

For example, the uninitialized .flags field could have the CLK_IS_CRITICAL
bit set, causing the framework to wrongly prepare the clk on registration.
This leads to the isp_xclk_prepare() callback being called, which in turn
calls to the omap3isp_get() function that increments the isp dev refcount.

Since this omap3isp_get() call is unexpected, this leads to an unbalanced
omap3isp_get() call that prevents the requested IRQ to be later enabled,
due the refcount not being 0 when the correct omap3isp_get() call happens.

Hugues Fruchet ce85705a2a media: ov5640: add HFLIP/VFLIP controls support
Add HFLIP/VFLIP controls support by setting registers REG21/REG20.
Useless values in hardcoded mode sequences are removed and
remaining binning values are now set after mode sequence being set.
Note that due to BSI (Back Side Illuminated) technology, image capture
is physically mirrored, mirror logic is so inversed in REG21 register
to cancel this effect.

Hans Verkuil e1a98c163e media: media.h: remove __NEED_MEDIA_LEGACY_API
The __NEED_MEDIA_LEGACY_API define is 1) ugly and 2) dangerous
since it is all too easy for drivers to define it to get hold of
legacy defines. Instead just define what we need in media-device.c
which is the only place where we need the legacy define
(MEDIA_ENT_T_DEVNODE_UNKNOWN).

Javier Martinez Canillas 1831af0923 media: Revert "[media] tvp5150: fix pad format frame height"
This reverts commit 0866df8dff.

The v4l uAPI documentation [0] makes clear that in the case of interlaced
video (i.e: field is V4L2_FIELD_ALTERNATE) the height refers to the number
of lines in the field and not the number of lines in the full frame (which
is twice the field height for interlaced formats).

So the original height calculation was correct, and it shouldn't had been
changed by the mentioned commit.

Ezequiel Garcia 9aecc03555 media: rockchip/rga: Fix broken .start_streaming
Currently, rga_buf_start_streaming() is expecting
pm_runtime_get_sync to return zero on success, which
is wrong.

As per the documentation, pm_runtime_get_sync increments
the device's usage counter and return its result.
This means it will typically return a positive integer
on success and a negative error code.

Therefore, rockchip-rga driver is currently unusable
failing to start_streaming in most cases. Fix it and
while here, cleanup the buffer return-to-core logic.

Alexandre Courbot 1946117b8f media: venus: keep resolution when adjusting format
When checking a format for validity, the resolution is reset to 1280x720
whenever the pixel format is not supported. This behavior can mislead
user-space into believing that this is the only resolution supported,
and looks strange considering that if we try/set the same format with
just the pixel format changed to a valid one, the call will this time
succeed without altering the resolution.

Resolution is managed independently of the pixel format, so remove this
reset.
