5393db43f4 V4L/DVB: cx25840: support new vbi ops to set/get VBI format
Also removed the bogus zeroing of fmt.sliced when setting up raw VBI.

Switching between raw and sliced VBI changed in 2.6.28 and this memset
should have been removed at that time. It was never noticed because
the bridge driver will fill in the fmt.vbi values anyway.

d922b8ea33 V4L/DVB: cx88: fix setting input when using DVB
In cx88-mpeg.c, there is code that sets core->input to CX88_VMUX_DVB.
However, this may be incorrect, since core->input is actually an
index to core->board.input[], which has not enough elements to be
indexed by the value of CX88_VMUX_DVB. So, the modified code searches
core->board.input[] for an input with a type of CX88_VMUX_DVB, and if
it does not find one, the index is simply set to zero.
The change may not have much effect, though, since it appears the only
case when core->input is actually used is when the current input is
being queried.

5a143b12eb V4L/DVB: ir-core: remove IR_TYPE_PD
Pulse-distance is not a protocol, it is a line coding (used by some protocols,
like NEC). Looking at the uses of IR_TYPE_PD, the real protocol seems to be
NEC in all cases (drivers/media/video/cx88/cx88-input.c is the only user).

So, remove IR_TYPE_PD while it is still easy to do so.

6718e8ad95 V4L/DVB: IR/imon: convert to ir-core protocol change handling
Drop the imon driver's internal protocol definitions in favor of using
those provided by ir-core. Should make ir-keytable Just Work for
switching protocol on the fly on the imon devices that support both the
native imon remotes and mce remotes.

The imon-no-pad-stabilize pseudo-protocol was dropped as a protocol, and
converted to a separate modprobe option (which it probably should have
been in the first place). On the TODO list is to convert this to an as yet
unwritten protocol-specific options framework.

While the mce remotes obviously map to IR_TYPE_RC6, I've yet to look at
what the actual ir signals from the native imon remotes are, so for the
moment, imon native ir is mapped to IR_TYPE_OTHER. Nailing it down more
accurately is also on the TODO list.

1babcb460f V4L/DVB: V4L: File handles
This patch adds a list of v4l2_fh structures to every video_device.
It allows using file handle related information in V4L2. The event interface
is one example of such use.

The use of v4l2_fh is not mandatory for drivers.

96d8eab5d0 V4L/DVB: [v5,2/2] v4l: Add a mem-to-mem videobuf framework test device
This is a virtual device driver for testing the memory-to-memory framework.

This virtual device uses in-memory buffers for both its source and destination.
It is capable of multi-instance, multi-buffer-per-transaction operation
(via the mem2mem framework).

7f98639def V4L/DVB: add memory-to-memory device helper framework for videobuf
A mem-to-mem device is a device that uses memory buffers passed by
userspace applications for both their source and destination data. This
is different from existing drivers, which utilize memory buffers for either
input or output, but not both.

In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type.

Examples of such devices would be: image 'resizers', 'rotators',
'colorspace converters', etc.

This patch adds a separate Kconfig sub-menu for mem-to-mem devices as well.

The enum fe_caps provides flags that allow an application to detect
whether a device is capable of handling various modulation types etc.
A flag for detecting PSK_8, however, is missing.
This patch adds the flag FE_CAN_PSK_8 to frontend.h and implements
it for the gp8psk-fe.c and cx24116.c driver (apparently the only ones
with PSK_8). Only the gp8psk-fe.c has been explicitly tested, though.

b400f09246 V4L/DVB: Fix default state Beholder H6 tuner
The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF. This
tuner has internal I2C switch. This switch switch I2C bus between DVB-T
and IF part. Default state is DVB-T. When module saa7134 is load it
can't find IF tda9887 and disable analog TV mode.

Sets internal I2C switch of the tuner to IF by send special value to the
tuner as for receive analog TV from low band. It can be usefule for
other cards.

I didn't set configure a tuner by a tuner model because this tuner can
have different I2C address. May be we can do it later after discuss for
more robust support a tuners.

0a062033f7 Revert "V4L/DVB (11906): saa7134: Use v4l bounding/alignment function"
This reverts commit bc52d6eb44.

On newer kernels, a saa7134 board stopped to display TV video output
properly. After a bisect, I found it as the commit causing the issue.
Turns out that v4l_bound_align_image isn't doing the same bounding
calculation as manually done previously in saa7134_try_fmt_vid_cap.

What isn't equal is the calculation done in clamp align, while
previously it did "f->fmt.pix.width &= ~0x03", clamp_align function
does "Round to nearest aligned value" as stated in the comment, which
yields a different result. If I comment the round calculation in
clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask",
I get it fixed too, because this way the calculation is the same then.

3f113e3610 V4L/DVB: ir-core: move subsystem internal calls to ir-core-priv.h
ir-core.h has the kABI to be used by the bridge drivers, when needing to register
IR protocols and pass IR events. However, the same file also contains IR subsystem
internal calls, meant to be used inside ir-core and between ir-core and the raw
decoders.

Better to move those functions to an internal header, for some reasons:

1) Header will be a little more cleaner;

2) It avoids the need of recompile everything (bridge/hardware drivers, etc),
   just because a new decoder were added, or some other internal change were needed;

3) Better organize the ir-core API, splitting the functions that are internal to
   IR core and the ancillary drivers (decoders, lirc_dev) from the features that
   should be exported to IR subsystem clients.

724e249550 V4L/DVB: Teach drivers/media/IR/ir-raw-event.c to use durations
drivers/media/IR/ir-raw-event.c is currently written with the assumption
that all "raw" hardware will generate events only on state change (i.e.
when a pulse or space starts).

However, some hardware (like mceusb, probably the most popular IR receiver
out there) only generates duration data (and that data is buffered so using
any kind of timing on the data is futile).

Furthermore, using signed int's to represent pulse/space durations is a
well-known approach when writing ir decoders.

With this patch:

- s64 int's are used to represent pulse/space durations in ns

- a workqueue is used to decode the ir protocols outside of interrupt context

- #defines are added to make decoders clearer

- decoder reset is implemented by passing a zero duration to the kfifo queue
  and decoders are updated accordingly

b320f80a6a V4L/DVB: ir-core: properly present the supported and current protocols
Hardware decoders have a more limited set of decoders than software ones.
In general, they support just one protocol at a given time, but allow
changing between a few options.

Rename the previous badly named "current_protocol" as just "protocol",
meaning the current protocol(s) accepted by the driver, and
add a "support_protocols" to represent the entire universe of supported
protocols by that specific hardware.

As commented on http://lwn.net/Articles/378884/, the "one file, one value"
rule doesn't fit nor does make much sense for bitmap or enum values. So, the
supported_protocols will enum all supported protocols, and the protocol
will present all active protocols.

Some devices have in-hardware Remote Controller decoder, while others
need a software decoder to get the IR code. As each software decoder
can be enabled/disabled individually, allowing multiple protocol
decoding capability.

On the other hand, hardware decoders have a limited protocol
support, often being able of decoding just one protocol each time.
So, each type needs a different set of capabilities to control the

I know we haven't reached any agreement on whether transmission will

least make the device name non-receive-specific which will make it
possible in the future (and if a different approach is finally

a table with IR_TYPE_UNKNOWN would make change_protocol to return -EINVAL.

As this function is fundamental to initialize some data, including a
callback to the getkey function, this caused the driver to stop working,
hanging the machine most of the times.

The fix were simply to add a handler for the IR type, but, to avoid further
issues, explicitly call change_protocol and handle the error before
initializing the IR. Also, let input_dev to start/stop IR handling,
after the opening of the input device.

9dfe4e8339 V4L/DVB: ir-core: Add support for badly-implemented hardware decoders
A few hardware Remote Controller decoders, even using a standard protocol,
aren't able to provide the entire scancode. Due to that, the capability
of using other IR's are limited on those hardware.

Adds a way to indicate to ir-core what are the bits that the hardware
provides, from a scancode, allowing the addition of a complete IR table
to the kernel and allowing a limited support for changing the Remote

2f16f6315f V4L/DVB: ir-nec-decoder: Reimplement the entire decoder
Thanks to Andy Walls <awalls@md.metrocast.net> for pointing me his
code, that gave me some ideas to better implement it.

After some work with saa7134 bits, I found a way to catch both IRQ
edge pulses. By enabling it, the NEC decoder can now take both
pulse and spaces into account, making it more precise.

Instead of the old strategy of handling the events all at once,
this code implements a state machine. Due to that, it handles
individual pulse or space events, validating them against the
protocol, producing a much more reliable decoding.

With the new implementation, the protocol trailer bits are properly
handled, making possible for the repeat key to work.

Also, the code is now capable of handling both NEC and NEC extended
IR devices. With NEC, it produces a 16 bits code, while with NEC
extended, a 24 bits code is returned.

All knowledge of keystates etc is now internal to ir-keytable.c

it doesn't belong).

In addition, I've changed the API slightly so that ir_input_dev is
passed as the first argument rather than input_dev. If we're ever
going to support multiple keytables we need to move towards making
ir_input_dev the main interface from a driver POV and obscure away
the input_dev as an implementational detail in ir-core.

b3074c0a3f V4L/DVB: drivers/media/IR - improve keytable code
The attached patch rewrites much of the keytable code in
drivers/media/IR/ir-keytable.c.

The scancodes are now inserted into the array in sorted
order which allows for a binary search on lookup.

The code has also been shrunk by about 150 lines.

In addition it fixes the following bugs:

Any use of ir_seek_table() was racy.

ir_dev->driver_name is leaked between ir_input_register() and
ir_input_unregister().

ir_setkeycode() unconditionally does clear_bit() on dev->keybit
when removing a mapping, but there might be another mapping with
a different scancode and the same keycode.

This version has been updated to incorporate patch feedback from
Mauro Carvalho Chehab.

bdf1c98e42 V4L/DVB: saa7134: Add support for both positive and negative edge IRQ
The code that enables IRQ for the Remote Controller on saa7134 is a little
messy: it is outside saa7134-input, it checks if RC is GPIO based, and
it mixes both serial raw decode with parallel reads from a hardware-based
IR decoder.

Also, currently, it doesn't allow to trigger both transition edges at GPIO16
and GPIO18 lines. A rework on the code is needed to provide a better way
to specify what saa7134-input needs, maybe even moving part of the code from
saa7134-core and saa7134-cards into saa7134-input.

Yet, as a large rework is happening at RC core, it is better to wait until
the core changes stablize, in order to rework saa7134 RC internals.While
this don't happen, let's just change the logic a little bit to allow
enabling IRQ to be generated on both edge transitions, in order to better
support pulse/space raw decoders.

6686fa6917 V4L/DVB: Break Remote Controller keymaps into modules
The original Remote Controller approach were very messy: a big file,
that were part of ir-common kernel module, containing 64 different
RC keymap tables, used by the V4L/DVB drivers.

Better to break each RC keymap table into a separate module,
registering them into rc core on a process similar to the fs/nls tables.

As an userspace program is now in charge of loading those tables,
adds an option to allow the complete removal of those tables from
kernelspace.

Yet, on embedded devices like Set Top Boxes and TV sets, maybe the
only available input device is the IR. So, we should keep allowing
the usage of in-kernel tables, but a latter patch should change
the default to 'n', after giving some time for distros to add
the v4l-utils with the ir-keytable program, to allow the table
load via userspace.

IR is an alias for Infrared Remote, while RC is an alias for Remote

While currently all implementations are with Infrared Remote Controller,
this subsystem is not meant to be used only by IR type of RC's. So,
as discussed on both linux-media and linux-input, the better is to
rename the subsystem as Remote Controller.

While, currently, the only application that uses the /sys/class/irrcv is
ir-keytable application, and its sysfs support works only with the
current linux-next code, it is still possible to change the userspace API
without the risk of breaking applications. So, better to rename this
sooner than later.

Later patches will be needed to rename the files and to move them away
from drivers/media, but this is not a critical issue. So, for now,
let's just change the name of the sysfs class/nodes.

At raw_decode mode, the key is processed after the end of a timer. The
previous code resets the timer every time something is received at the IR
port. While this works fine with IR's that don't implement repeat, like
Avermedia RM-JX IR, it keeps waiting until keydown, on IR's that implement
NEC repeat command, like the Terratec yellow.

The solution is to change the behaviour to do the timeout after the first
received data.

The timeout is currently set to 15 ms, as it works fine with NEC protcocol.
It may need some adjustments to support other protocols and to better handle
spurious detections that may happen with some IR sensors.

For the sequence streamon -> streamoff and again s_input, it fails
to lock the signal, since streamoff puts TVP514x into power off state
which leads to failure in sub-sequent s_input.

So add powerup sequence in s_routing (if disabled), since it is
important to lock the signal at this stage.

085b54a24f V4L/DVB: V4L: vpfe_capture: Add call back function for interrupt clear for vpfe_cfg
For the devices like AM3517, it is expected that driver clears the
interrupt in ISR. Since this is device spcific, callback function
added to the platform_data.
