It is common that media drivers call subdev ops in source subdevs, and
pass NULL as the state. This was the way to indicate that the callee
should use the callee's private active state.
E.g.:
v4l2_subdev_call(priv->source_sd, pad, get_fmt, NULL, &sd_fmt);
Now that we have a real subdev active state in the v4l2_subdev struct,
we want the caller to pass a proper state (when available). And
furthermore, the state should be locked.
This would mean changing all the callers, which is the long term goal.
To fix this issue in the short term, let's add an extra wrapper layer to
all v4l2_subdev_call_pad_wrappers which deal with states. These wrappers
handle the state == NULL case by using the locked active state instead
(when available).

The V4L2 subdevs have managed without centralized locking for the state
(previously pad_config), as the try-state is supposedly safe (although I
believe two TRY ioctls for the same fd would race), and the
active-state, and its locking, is managed by the drivers internally.
We now have active-state in a centralized position, and need locking.
Strictly speaking the locking is only needed for new drivers that use
the new state, as the current drivers continue behaving as they used to.
However, active-state locking is complicated by the fact that currently
the real active-state of a subdev is split into multiple parts: the new
v4l2_subdev_state, subdev control state, and subdev's internal state.
In the future all these three states should be combined into one state
(the v4l2_subdev_state), and then a single lock for the state should be
sufficient.
But to solve the current split-state situation we need to share locks
between the three states. This is accomplished by using the same lock
management as the control handler does: we use a pointer to a mutex,
allowing the driver to override the default mutex. Thus the driver can
do e.g.:
sd->state_lock = sd->ctrl_handler->lock;
before calling v4l2_subdev_init_finalize(), resulting in sharing the
same lock between the states and the controls.
The locking model for active-state is such that any subdev op that gets
the state as a parameter expects the state to be already locked by the
caller, and expects the caller to release the lock.

At the moment when a subdev op is called, the TRY subdev state
(subdev_fh->state) is passed as a parameter even for the ACTIVE case, or
alternatively a NULL can be passed for ACTIVE case. This used to make
sense, as the ACTIVE state was handled internally by the subdev drivers.
We now have a state for the ACTIVE case in a standard place, and can
pass that also to the drivers. This patch changes the subdev ioctls to
either pass the TRY or ACTIVE state to the subdev.
Unfortunately many drivers call ops from other subdevs, and implicitly
pass NULL as the state, so this is just a partial solution. A coccinelle
spatch could perhaps be created which fixes the drivers' subdev calls.
For all current upstream drivers this doesn't matter, as they do not
expect to get a valid state for ACTIVE case. But future drivers which
support multiplexed streaming and routing will depend on getting a state
for both active and try cases.
For new drivers we can mandate that the pipelines where the drivers are
used need to pass the state properly, or preferably, not call such
subdev ops at all.
However, if an existing subdev driver is changed to support multiplexed
streams, the driver has to consider cases where its ops will be called
with NULL state. The problem can easily be solved by using the
v4l2_subdev_lock_and_get_active_state() helper, introduced in a follow
up patch.
Another follow up patch adds wrappers for pad ops dealing with subdev
state, which automate the use of
v4l2_subdev_lock_and_get_active_state() for cases where the state is
NULL.

Matching on device fwnode handles is deprecated in favour of endpoint
fwnode handles. Switch the __v4l2_async_nf_add_fwnode_remote() function
to use the latter. The match code handles backward compatibility by
falling by to the device fwnode handle, so this shouldn't introduce any
regression.

The bus_info field is set by most drivers based on the type of the device
bus as well as the name of the device. Do this in v4l_querycap() so
drivers don't need to. This keeps compatibility with non-default and silly

Upon an async fwnode match, there's some typical behaviour that the
notifier and matching subdev will want to do. For example, a notifier
representing a sensor matching to an async subdev representing its
VCM will want to create an ancillary link to expose that relationship
to userspace.
To avoid lots of code in individual drivers, try to build these links
within v4l2 core.

Add support for MEDIA_BUS_FMT_JPEG_1X8 media bus code to the
CSIS driver.
The MEDIA_BUS_FMT_JPEG_1X8 code is mapped to the RAW8 CSI-2 Data Type,
while the CSI-2 specification suggests to use User Defined Data Type 1.
As reported in the comment, the CSIS interface captures arbitrary Data
Types by using a pixel sampling mode not supported by the IP core
connected to it on i.MX SoCs.
As some sensors, such as OV5640, support sending JPEG data on the RAW8
Data Type and capture operations work correcty with such configuration,
map MEDIA_BUS_FMT_JPEG_1X8 to Data Type 0x2a.

Allow drivers to change the transmit timeout value, i.e. after how
long should a transmit be considered 'lost', i.e. the corresponding
cec_transmit_done_ts was never called.
Some CEC devices have their own timeout, and so this timeout value must be
longer than that hardware timeout value. If it is shorter then the
framework would consider the transmit lost, even though it is effectively
still in progress at the hardware level.

The results of non-blocking transmits were not correctly communicated
to userspace.
Specifically:
1) if a non-blocking transmit was canceled, then rx_status wasn't set to 0
as it should.
2) if the non-blocking transmit succeeded, but the corresponding reply
never arrived (aborted or timed out), then tx_status wasn't set to 0
as it should, and rx_status was hardcoded to ABORTED instead of the
actual reason, such as TIMEOUT. In addition, adap->ops->received() was
never called, so drivers that want to do message processing themselves
would not be informed of the failed reply.

If a transmit-in-progress was canceled, then, once the transmit
is done, mark it as aborted and refrain from retrying the transmit.
To signal this situation the new transmit_in_progress_aborted field is
set to true.
The old implementation would just set adap->transmitting to NULL and
set adap->transmit_in_progress to false, but on the hardware level
the transmit was still ongoing. However, the framework would think
the transmit was aborted, and if a new transmit was issued, then
it could overwrite the HW buffer containing the old transmit with the
new transmit, leading to garbled data on the CEC bus.

Don't enable/disable the adapter if the first fh is opened or the
last fh is closed, instead do this when the adapter is configured
or unconfigured, and also when we enter Monitor All or Monitor Pin
mode for the first time or we exit the Monitor All/Pin mode for the
last time.
However, if needs_hpd is true, then do this when the physical
address is set or cleared: in that case the adapter typically is
powered by the HPD, so it really is disabled when the HPD is low.
This case (needs_hpd is true) was already handled in this way, so
this wasn't changed.
The problem with the old behavior was that if the HPD goes low when
no fh is open, and a transmit was in progress, then the adapter would
be disabled, typically stopping the transmit immediately which
leaves a partial message on the bus, which isn't nice and can confuse
some adapters.
It makes much more sense to disable it only when the adapter is
unconfigured and we're not monitoring the bus, since then you really
won't be using it anymore.
To keep track of this store a CEC activation count and call adap_enable
only when it goes from 0 to 1 or back to 0.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

The ti-vpe/ sub-directory does not only contain the VPE-specific things.
It also contains the CAL driver, which is a completely different
subsystem. This is also not a good place to add new drivers for other TI
platforms since they will all get mixed up.
Separate the VPE and CAL parts into different sub-directories and rename
the ti-vpe/ sub-directory to ti/. This is now the place where new TI
platform drivers can be added.

Just like media bus drivers, place platform drivers on a
submenu, in order to better organize user-selection:
Media drivers --->
*** media drivers ***
[*] Media USB Adapters --->
[*] Media PCI Adapters --->
-*- Radio Adapters --->
[*] Media platform devices --->
*** MMC/SDIO DVB adapters ***
< > Siano SMS1xxx based MDTV via SDIO interface
[*] V4L test drivers --->
[*] DVB test drivers --->
*** FireWire (IEEE 1394) Adapters ***
<*> FireDTV and FloppyDTV
*** common driver options ***
[ ] Enable Remote Controller support for Siano devices
[ ] Enable debugfs for smsdvb
As this submenu depends on MEDIA_PLATFORM_DRIVERS and defaults to "y",
there's no need to change already-existing .config entries, nor touch
the several make *_defconfig.
