f8e2e3eab8 [media] Add v4l2 subdev driver for NOON010PC30L image sensor
Add I2C/V4L2 subdev driver for Siliconfile NOON010PC30 CIF camera.
The driver implements basic functionality, i.e. CIF/QCIF/QQCIF
resolution and color format selection, automatic/manual color
balance control. Other functions like cropping, rotation/flip,
exposure etc. can be easily implemented if needed.

b25748fe61 [media] v4l: videobuf2: add read() and write() emulator
Add a generic file io (read and write) emulator for videobuf2. It uses
MMAP memory type buffers and generic vb2 calls: req_bufs, qbuf and
dqbuf. Video date is being copied from mmap buffers to userspace with
standard copy_to_user() function. To add support for file io the driver
needs to provide an additional callback - read_setup or write_setup. It
should provide the default number of buffers used by emulator and flags.

With these flags one can detemine the style of read() or write()
emulation. By default 'streaming' style is used. With
VB2_FILEIO_READ_ONCE flag one can select 'one shot' mode for read()
emulator. With VB2_FILEIO_WRITE_IMMEDIATE flag one can select immediate
conversion of write calls to qbuf for write() emulator, so the vb2 will
not wait until each buffer is filled completely before queueing it to
the driver.

e23ccc0ad9 [media] v4l: add videobuf2 Video for Linux 2 driver framework
Videobuf2 is a Video for Linux 2 API-compatible driver framework for
multimedia devices. It acts as an intermediate layer between userspace
applications and device drivers. It also provides low-level, modular
memory management functions for drivers.

Videobuf2 eases driver development, reduces drivers' code size and aids in
proper and consistent implementation of V4L2 API in drivers.

Videobuf2 memory management backend is fully modular. This allows custom
memory management routines for devices and platforms with non-standard
memory management requirements to be plugged in, without changing the
high-level buffer management functions and API.

The framework provides:
- implementations of streaming I/O V4L2 ioctls and file operations
- high-level video buffer, video queue and state management functions
- video buffer memory allocation and management

739ff04f63 [media] technisat-usb2: added driver for Technisat's USB2.0 DVB-S/S2 receiver
This patch is adding support for Technisat's new USB2.0 DVB-S/S2 receiver
device. The development was sponsored by Technisat.

The Green led is toggle depending on the frontend-state. The Red LED is turned
on all the time.

The MAC address reading from the EEPROM along with the
LRC-method to check whether its valid.

Support for the IR-receiver of the Technisat USB2 box. The keys of
small, black remote-control are built-in, repeated key behaviour are
simulated.

The i2c-mutex of the dvb-usb-structure is used as a general mutex for
USB requests, as there are 3 threads racing for atomic requests
consisting of multiple usb-requests.

A module option is there which disables the toggling of LEDs by the
driver on certain triggers. Useful when being used in a "dark"
environment.

intending to use is a milliseconds to microseconds. Lets move the
defines to a common location, expand and standardize them a touch, so
that we now have:

  MS_TO_NS - milliseconds to nanoseconds
  MS_TO_US - milliseconds to microseconds
  US_TO_NS - microseconds to nanoseconds

45f6f84af3 [media] v4l2-subdev: add (un)register internal ops
Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.

So this patch adds a struct with internal ops that the v4l2 core can call.

Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.

It is expected that in the future open and close ops will also be added.

3c7c9370fb [media] v4l2-subdev: remove core.s_config and v4l2_i2c_new_subdev_cfg()
The core.s_config op was meant for legacy drivers that needed to work with old
pre-2.6.26 kernels. This is no longer relevant. Unfortunately, this op was
incorrectly called from several drivers.

Replace those occurences with proper i2c_board_info structs and call
v4l2_i2c_new_subdev_board.

After these changes v4l2_i2c_new_subdev_cfg() was no longer used, so remove
that function as well.

b088ba658b [media] rc: Properly name the rc_map struct
The struct that describes a rc mapping had an weird and long name.
We should properly name it, to make easier for developers to work

2eb2583277 [media] ir-kbd-i2c: add rc_dev as a parameter to the driver
There are several fields on rc_dev that drivers can benefit. Allow drivers
to pass it as a parameter to the driver.

For now, the rc_dev parameter is optional. If drivers don't pass it, create
them internally. However, the best is to create rc_dev inside the drivers,
in order to fill other fields, like open(), close(), driver_name, etc.
So, a latter patch making it mandatory and changing the caller drivers is
welcome.

d8b4b5822f [media] ir-core: make struct rc_dev the primary interface
This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.

This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.

The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()

The only remaining drivers to depend on VIDEO_IR are bt8xx and
saa7134 (ir_rc5_timer_end is the only function exported by

2997137be8 [media] ir-core: convert drivers/media/video/cx88 to ir-core
This patch converts the cx88 driver (for sampling hw) to use the
decoders provided by ir-core instead of the separate ones provided
by ir-functions (and gets rid of those).

The value for MO_DDS_IO had a comment saying it corresponded to
a 4kHz samplerate. That comment was unfortunately misleading. The
actual samplerate was something like 3250Hz.

The current value has been derived by analyzing the elapsed time
between interrupts for different values (knowing that each interrupt
corresponds to 32 samples).

2f6e240479 [media] SoC Camera: add driver for OV6650 sensor
This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found
on OMAP1 SoC based Amstrad Delta videophone.

Since I have no experience with camera sensors, and the sensor documentation I
was able to find was not very comprehensive, I left most settings at their
default (reset) values, except for:
- those required for proper mediabus parameters and picture geometry and
  format setup,
- those used by controls.
Resulting picture quality may be far from perfect, but better than nothing.

In order to be able to get / set the sensor frame rate from userspace, I
decided to provide two not yet SoC camera supported operations, g_parm and
s_parm. These can be used after applying patch 4/6 from this series,
"SoC Camera: add support for g_parm / s_parm operations".

Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

bdc621fced [media] SoC Camera: add driver for OMAP1 camera interface
This is a V4L2 driver for TI OMAP1 SoC camera interface.

Both videobuf-dma versions are supported, contig and sg, selectable with a
module option. The former uses less processing power, but often fails to
allocate contignuous buffer memory. The latter is free of this problem, but
generates tens of DMA interrupts per frame. If contig memory allocation ever
fails, the driver falls back to sg automatically on next open, but still can
be switched back to contig manually. Both paths work stable for me, even
under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the
oldest, least powerfull OMAP1 implementation.

The interface generally works in pass-through mode. Since input data byte
endianess can be swapped, it provides up to two v4l2 pixel formats per each of
several soc_mbus formats that have their swapped endian counterparts.

Boards using this driver can provide it with the following platform data:
- if and what freqency clock is expected by an on-board camera sensor,
- what is the maximum pixel clock that should be accepted from the sensor,
- what is the polarity of the sensor provided pixel clock,
- if the interface GPIO line is connected to a sensor reset/powerdown input
  and what is the input polarity.

Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

be1f985ffa [media] IR/lirc: further ioctl portability fixups
>From Joris van Rantwijk <jorispubl@xs4all.nl>:

	I tested lirc_serial and found that it works fine.
	Except the LIRC ioctls do not work in my 64-bit-kernel/32-bit-user
	setup. I added compat_ioctl entries in the drivers to fix this.

	While doing so, I noticed inconsistencies in the argument type of
	the LIRC ioctls. All ioctls are declared in lirc.h as having argument
	type __u32, however there are a few places where the driver calls
	get_user/put_user with an unsigned long argument.

	The patch below changes lirc_dev and lirc_serial to use __u32 for all
	ioctl arguments, and adds compat_ioctl entries.
	It should probably also be done in the other low-level drivers,
	but I don't have hardware to test those.

I've dropped the .compat_ioctl addition from Joris' original patch,
as I swear the non-compat definition should now work for both 32-bit
and 64-bit userspace. Technically, I think we still need/want a
in getting a reply to you).

Currently videobuf uses the vb_lock mutex to lock its data structures.
But this locking will (optionally) move into the v4l2 core, which means
that in that case vb_lock shouldn't be used since the external lock is already
held.

Prepare for this by adding a pointer to such an external mutex and
don't lock if that pointer is set.

ee6869afc9 V4L/DVB: v4l2: add core serialization lock
Drivers can optionally set a pointer to a mutex in struct video_device.
The core will use that to lock before calling open, read, write, unlocked_ioctl,
poll, mmap or release.

Updated the documentation as well and ensure that v4l2-event knows about the
lock: it will unlock it before doing a blocking wait on an event and relock it
afterwards.

Ensure that the 'video_is_registered' check is done when the lock is held:
a typical disconnect will take the lock as well before unregistering the
device nodes, so to prevent race conditions the video_is_registered check
should also be done with the lock held.

The imon driver currently reimplements its own version of ir_keyup
(along with key release timer functionality also already present in the
core IR code). A follow-up imon patch will make use of ir_keyup and the
IR stack's key release code.

Trivial extraction from David Härdeman's pending rc-core merge and
device interface abstraction patchset to facilitate merging a patch
based on his imon input dev split patch ahead of the larger churn, which
is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are
merged in mainline).

creating an #ifdef mess.

The hg repository dropped support for kernels < 2.6.26 so we can remove this
header. All i2c drivers that used it have now been converted to use proper
i2c code. The header was a hack, but it did its job well. So I would call
this an honorable removal. :-)

226c0eeaea V4L/DVB: videotext: remove this obsolete API
Remove the vtx (aka videotext aka teletext) API from the v4l2 core.
This API was scheduled for removal in kernel 2.6.35.

The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.

In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.

The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

7a569f524d V4L/DVB: IR/streamzap: functional in-kernel decoding
This patch makes in-kernel decoding with the stock Streamzap PC Remote
work out of the box. There are quite a few things going on in this
patch, all related to getting this working:

1) I had to enable reporting of a long space at the end of each signal,
   or I had weird buffering and keybounce issues.

2) The keymap has been reworked slightly to match actual decoded values,
   the first edition was missing the pre-data bits present in the lirc
   config file for this remote.

3) There's a whole new decoder included, specifically for the
   not-quite-RC5 15-bit protocol variant used by the Streamzap PC
   Remote. The decoder, while usable with other recievers (tested with
   an mceusb receiver), will only be loaded by the streamzap driver, as
   its likely not of use in almost all other situations. This can be
   revisited if/when all keytable loading (and disabling of unneeded
   protocol decoder engines) is moved to userspace, but for now, I think
   this makes the most sense.

Note that I did try to enable handling the streamzap RC5-ish protocol in
the current RC5 decoder, but there's no particularly easy way to tell if
its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then,
in testing an attempted decoder merge, only 2/3 of the keys were
properly recognized as being the 15-bit variant and decoded correctly,
the rest were close enough to compliant with 14-bit that they were
decoded as such (but they have overlap with one another, and thus we
can't just shrug and use the 14-bit decoded values).

Also of note in this patch is the removal of the streamzap driver's
internal delay buffer. Per discussion w/Christoph, it shouldn't be
needed by lirc any longer anyway, and it doesn't seem to make any
difference to the in-kernel decoder engine. That being the case, I'm
yanking it all out, as it greatly simplifies the driver code.
