address for the next run. Rename it to set_memory and pass it a new

The Timberdale FPGA video driver has not seen any real development
since 2011 (and very little before that).
One of the problems with the timblogiw driver is that it uses videobuf
instead of the newer vb2 framework. The long term goal is to either
convert or remove any driver still using videobuf. Since none of the
core v4l developers has the hardware, we cannot convert it ourselves.
As far as I can tell it was only used in an Intel demo board in 2009
using Meego:
http://www.chinait.com/intelcontent/intelprc/admin/PDFFile/20106411545.pdf
which has since been superseded.
Moving this driver to staging is the first step towards removal. After 2 or
3 kernel cycles it will be removed altogether unless someone steps up to
clean up this driver.

Sometimes when a Bayer pixelformat is selected the rendering of the OSD text
by vivid was all wrong: every other line of the text was shifted by half the width
or more.
It turned out that to render Bayer formats the interleaved boolean is set to true
in the tpg. This mode indicates a semi-biplanar mode where two interleaved planes
are used to render the frame. From outside the tpg it looks like a single plane,
but internally it is two planes.
However, in the tpg_s_bytesperline() function the interleaved bool wasn't checked
and only the bytesperline value for plane 0 was updated. But for the interleaved
mode the same value has to be copied to bytesperline[1] as well.
The effect was that whatever old value was left in bytesperline[1] was used, which
caused all sorts of weird and seemingly unpredictable shifts.

omapfb and omapdrm have shared low level drivers (omapdss and panel drivers),
making further development of omapdrm difficult. After these patches omapfb and
omapdrm have their own versions of the drivers, which are more or less

omapfb and omapdrm have shared low level drivers (omapdss and panel
drivers), making further development of omapdrm difficult. After
these patches omapfb and omapdrm have their own versions of the

soon.
This also means that omapfb (everything under drivers/video/fbdev/omap2/)
is now in maintenance mode, and all new development will be done for

Currently, v4l2_device_register() doesn't use the media_device
struct. So, calling media_device_init() could be called either
before or after v4l2_device_register().
Yet, it is a good practice to initialize everything before calling
the register functions. Also, the other drivers call
media_device_init() before registering the V4L2 device.
So, move the call for media_device_init() to happen earlier on
exynos4-is and s3c-camif.
This is just a cleanup patch.

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.
To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().
The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.
Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

The for loop in the vsp1_create_entities() function that create the links,

it uses continue to force the next iteration of the loop to take place and

The entities to video nodes links were created on separate functions for
each ISP module but since the only thing that these functions do is to
call media_create_pad_link(), there's no need for that indirection level
and all link creation logic can be just inlined in the caller function.
Also, since the only possible failure for the link creation is a memory
allocation, there is no need for error messages since the core already
reports a very verbose message in that case.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

Instead of relying on media subtype, use the new macros to detect
if an entity is a subdev or an A/V DMA entity.
Please note that most drivers assume that there's just AV_DMA or
V4L2 subdevs. This is not true anymore, as we've added MC support
for DVB, and there are plans to add support for ALSA and FB/DRM
too.
Ok, on the current pipelines supported by those drivers, just V4L
stuff are there, but, assuming that some day a pipeline that also
works with other subsystems will ever added, it is better to add
explicit checks for the AV_DMA stuff.

The omap3isp driver parses the graph endpoints to know how many subdevices
needs to be registered async and register notifiers callbacks for to know
when these are bound and when the async registrations are completed.
Currently the entities pad are linked with the correct ISP input interface
when the subdevs are bound but it happens before entitities are registered
with the media device so that won't work now that the entity links list is
initialized on device registration.
So instead creating the pad links when the subdevice is bound, create them
on the complete callback once all the subdevices have been bound but only
try to create for the ones that have a bus configuration set during bound.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).
