The use of current_norm to keep track of the current standard has been
deprecated for quite some time. Now that all drivers that were using it
have been converted to use g_std we can drop it from the core.
It was a bad idea to introduce this at the time: since it is a per-device
node field it didn't work for drivers that create multiple nodes, all sharing
the same tuner (e.g. video and vbi nodes, or a raw video node and a compressed
video node). In addition it was very surprising behavior that g_std was
implemented in the core. Often drivers implemented both g_std and current_norm,
because they didn't understand how it should be used.
Since the benefits were very limited (if they were there at all), it is better
to just drop it and require that drivers just implement g_std.

After the FIMC-IS driver addition the assumptions made in the link_notify

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

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.

FireWire upper layer drivers are converted from generic
struct driver.probe() and .remove()
to bus-specific
struct fw_driver.probe() and .remove().
The new .probe() adds a const struct ieee1394_device_id *id argument,
indicating the entry in the driver's device identifiers table which
matched the fw_unit to be probed. This new argument is used by the
snd-firewire-speakers driver to look up device-specific parameters and
methods. There is at least one other FireWire audio driver currently in
development in which this will be useful too.
The new .remove() drops the unused error return code.
Although all in-tree drivers are being converted to the new methods,
support for the old methods is left in place in this commit. This
allows public developer trees to merge this commit and then move to the
new fw_driver methods.

This patch uses the driver from openpli[1] as a template to restore the remote control support.
I had to divert from the original to use the in kernel rc protocol decoder. The key repetition does,
not seem to work but I cant find the problem in the driver. As a raw rc provider, no key table is

This fixes a NULL pointer deference when loading the cx88_dvb module for a
Hauppauge HVR4000.
The bugzilla bug report is here:
https://bugzilla.kernel.org/show_bug.cgi?id=56271
The cause is that the wm8775 is optional, so even though the board info says
there is one, it doesn't have to be there. Checking whether the module was
actually loaded is much safer.
Note that this driver is quite buggy when it comes to unloading and reloading
modules. Unloading cx8800 and reloading it again will still cause a crash,
most likely because either the i2c bus isn't unloaded at the right time and/or
the v4l2_device_unregister isn't called at the right time.

Throughout the zig-zag-implementations, inversion is taken into
account when reading and writing the CFR register, which contains
the derotator frequency. As swapping IQ signals changes the sign
of that register for example, the idea is to compensate that sign
change by multiplying the register value with the inversion enum
value.
The current enum values 0 and 1 for IQ_SWAP_OFF and IQ_SWAP_ON
don't work in the case IQ_SWAP_OFF, due to the multiplication by
zero (I've only found a single device which actually uses
IQ_SWAP_OFF in it's config).
I've changed the enum values to +1 and -1 to accommodate to the
intended usage.

It seems that current inversion handling addresses only the signal
routing on the PCB, i. e. IQ signals are either swapped or not.
But when the device is operated in a Satellite Channel Router (SCR)
environment, an additional inversion is required due to the way how
the SCR works. Therefore it makes sense to me to always enable auto
inversion handling and drop the enum value IQ_SWAP_AUTO.

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.

If we just declare the job finished here while the CODA is still
running, the call to v4l2_m2m_ctx_release in coda_release, which
is supposed to wait for a running job to finish, will return
immediately and free memory that the CODA is still using.
Just set the 'aborting' flag and let coda_irq_handler deal with it.

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.

In preparation for CODA7541 and CODA960 multi-stream support and for
replacement of the completion with a mutex lock, consolidate the

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.

Callback .start_streaming is called once for every queue,
so v4l2_ctrl_handler_setup was called twice during stream start.
Moving v4l2_ctrl_handler_setup to context initialization
reduces numbers of calls and seems to be more consistent with API.

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.

MFC v6 needs minimum number of output buffers to be queued
for encoder depending on the stream type and profile.
The patch modifies the driver so that encoding cannot be
started with lesser number of OUTPUT buffers than required.
This also fixes the crash happeninig during multi instance
encoder-decoder simultaneous run due to memory allocation
happening from interrupt context.
