Mauro Carvalho Chehab bbc62a18b6 [media] au0828: fix checks if dvb is initialized
dev->dvb is always not null, as it is an area at the dev
memory. So, checking if (dev->dvb) is always true.

Instead of this stupid check, what the code wants to do is
to know if the DVB was successully registered.

Fix it by checking, instead, for dvb->frontend. It should
also be sure that this var will be NULL if the device was
not properly initialized.

Instead of using printk(KERN_foo, use pr_foo() macros.

No functional changes.

Note: we should do the same for dprintk(), but that would
require to remove the dprintk levels. So, for now, let's
not touch on it.

Trying to make au0828 to suspend can do very bad things, as

Mauro Carvalho Chehab 2e0cc7ee75 [media] au0828-input: Be sure that IR is enabled at polling
When the DVB code sets the frontend, it disables the IR
INT, probably due to some hardware bug, as there's no code
there at au8522 frontend that writes on register 0xe0.

Fixing it at au8522 code is hard, as it doesn't know if the
IR is enabled or disabled, and just restoring the value of
register 0xe0 could cause other nasty effects. So, better
to add a hack at au0828-input polling interval to enable int,
if disabled.

Mauro Carvalho Chehab cfd0c77d08 [media] au0828: improve I2C speed
Commits 21dc61d3c0 and 7a1dd50b89 reduced the board I2C
speed to 20 MHz by default, due to a I2C stretch issue:
while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.

However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.

So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.

The basic API of rc-core used to be:

	dev->x = a;

which is a pretty common pattern in the kernel, after the introduction of

David Härdeman 120703f9eb [media] rc-core: document the protocol type
Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

David Härdeman af3a4a9bbe [media] dib0700: NEC scancode cleanup
the RC RX packet is defined as:

        struct dib0700_rc_response {
		...
                                u8 not_system;
                                u8 system;
		...
                u8 data;
                u8 not_data;

The NEC protocol transmits in the order:
        system
        not_system
        data
        not_data

Note that the code defines the NEC extended scancode as:

        scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data;

i.e.

        scancode = poll_reply->not_system << 16 |
                   poll_reply->system     << 8  |
                   poll_reply->data;

Which, if the order *is* reversed, would mean that the scancode that
gets defined is in reality:

        scancode = poll_reply->system     << 16 |
                   poll_reply->not_system << 8  |
                   poll_reply->data;

Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.

This patch changes the code to match my assumption (the generated scancode
should, however, not change).

Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Hans Verkuil 0d5e8c4313 [media] Fix 64-bit division fall-out from 64-bit control ranges
Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.

Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

NeilBrown 743162013d sched: Remove proliferation of wait_on_bit() action functions
The current "wait_on_bit" interface requires an 'action'
function to be provided which does the actual waiting.
There are over 20 such functions, many of them identical.
Most cases can be satisfied by one of just two functions, one
which uses io_schedule() and one which just uses schedule().

So:
 Rename wait_on_bit and        wait_on_bit_lock to
        wait_on_bit_action and wait_on_bit_lock_action
 to make it explicit that they need an action function.

 Introduce new wait_on_bit{,_lock} and wait_on_bit{,_lock}_io
 which are *not* given an action function but implicitly use
 a standard one.
 The decision to error-out if a signal is pending is now made
 based on the 'mode' argument rather than being encoded in the action
 function.

 All instances of the old wait_on_bit and wait_on_bit_lock which
 can use the new version have been changed accordingly and their
 action functions have been discarded.
 wait_on_bit{_lock} does not return any specific error code in the
 event of a signal so the caller must check for non-zero and
 interpolate their own error code as appropriate.

The wait_on_bit() call in __fscache_wait_on_invalidate() was
ambiguous as it specified TASK_UNINTERRUPTIBLE but used
fscache_wait_bit_interruptible as an action function.
David Howells confirms this should be uniformly
"uninterruptible"

The main remaining user of wait_on_bit{,_lock}_action is NFS
which needs to use a freezer-aware schedule() call.

A comment in fs/gfs2/glock.c notes that having multiple 'action'
functions is useful as they display differently in the 'wchan'
field of 'ps'. (and /proc/$PID/wchan).
As the new bit_wait{,_io} functions are tagged "__sched", they
will not show up at all, but something higher in the stack.  So
the distinction will still be visible, only with different
function names (gds2_glock_wait versus gfs2_glock_dq_wait in the
gfs2/glock.c case).

Since first version of this patch (against 3.15) two new action
functions appeared, on in NFS and one in CIFS.  CIFS also now
uses an action function that makes the same freezer aware
schedule call as NFS.

Hans Verkuil 3445857b22 [media] hdpvr: fix two audio bugs
When the audio encoding is changed the driver calls hdpvr_set_audio
with the current opt->audio_input value. However, that should have
been opt->audio_input + 1. So changing the audio encoding inadvertently
changes the input as well. This bug has always been there.

The second bug was introduced in kernel 3.10 and that broke the
default_audio_input module option handling: the audio encoding was
never switched to AC3 if default_audio_input was set to 2 (SPDIF input).

In addition, since starting with 3.10 the audio encoding is always set
at the start the first bug now always happens when the driver is loaded.
In the past this bug would only surface if the user would change the
audio encoding after the driver was loaded.

Also fixes a small trivial typo (bufffer -> buffer).

Antonio Ospite 2fe152451d [media] gspca: provide a mechanism to select a specific transfer endpoint
Currently gspca selects the first ISOC input endpoint as the input
transfer endpoint, however some devices can provide streams on endpoints
different then the first one, so some subdrivers (e.g. gspca_kinect) may
want to select a specific endpoint to use as a transfer endpoint.

Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that
it accepts a parameter which represents a specific endpoint address to
look for.

If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do
that in its sd_config() callback.

Mauro Carvalho Chehab 64ea37bbd8 [media] au0828: Only alt setting logic when needed
It seems that there's a bug at au0828 hardware/firmware
related to alternate setting: when the device is already at
alt 5, a further call causes the URBs to receive -ESHUTDOWN.

I found two different encarnations of this issue:

1) at qv4l2, it fails the second time we try to open the
video screen;
2) at xawtv, when audio underrun occurs, with is very
frequent, at least on my test machine.

The fix is simple: just check if alt=5 before calling
set_usb_interface().

Mauro Carvalho Chehab b9bc7d59b7 [media] dib8000: rename dib8000_attach to dib8000_init
Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.

It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.

dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
  given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
  doesn't print who loaded the module);
- after loading the module, it runs the function associated
  with the dynamic symbol.

When compiled as builtin, it just calls the function given to it.

As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.

In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.

We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization

So, let's rename the function that probes and init the hardware
to dib7000p_init.

Change handling of signal_lock on rs2000. Use ibuf[2] to detect
lock as there is a longer wait for lock to appear in ibuf[6].

Remove last_key and key_timeout and use jiffies plus 60ms
to detect that streaming is still active.

If the current jiffies is time_after the interrupt urb overdue and
clear signal lock.

Mauro Carvalho Chehab f6fef86341 [media] au0828: reset streaming when a new frequency is set
As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.

I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.

Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.

There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.

One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.

This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.

A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

backports. Drivers should also try to avoid generic namespaces
for things like this.

Olivier Langlois 3b35fc81e7 [media] uvcvideo: Fix clock param realtime setting
timestamps in v4l2 buffers returned to userspace are updated in
uvc_video_clock_update() which uses timestamps fetched from
uvc_video_clock_decode() by calling unconditionally ktime_get_ts().

Hence setting the module clock param to realtime has no effect before
this patch.

This has been tested with ffmpeg:

ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 30 -i /dev/video0 \
 -f alsa -acodec pcm_s16le -ar 16000 -ac 1 -i default \
 -c:v libx264 -preset ultrafast \
 -c:a libfdk_aac \

Hans Verkuil e37559b22c [media] vb2: stop_streaming should return void
The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.

The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.

The pwc amd sdr-msi3101 drivers both had this construction:

        if (mutex_lock_interruptible(&s->v4l2_lock))
                return -ERESTARTSYS;

This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.

We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

Linus Torvalds 3c83e61e67 Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
 "The main set of series of patches for media subsystem, including:
   - document RC sysfs class
   - added an API to setup scancode to allow waking up systems using the
     Remote Controller
   - add API for SDR devices.  Drivers are still on staging
   - some API improvements for getting EDID data from media
     inputs/outputs
   - new DVB frontend driver for drx-j (ATSC)
   - one driver (it913x/it9137) got removed, in favor of an improvement
     on another driver (af9035)
   - added a skeleton V4L2 PCI driver at documentation
   - added a dual flash driver (lm3646)
   - added a new IR driver (img-ir)
   - added an IR scancode decoder for the Sharp protocol
   - some improvements at the usbtv driver, to allow its core to be
     reused.
   - added a new SDR driver (rtl2832u_sdr)
   - added a new tuner driver (msi001)
   - several improvements at em28xx driver to fix PM support, device
     removal and to split the V4L2 specific bits into a separate
     sub-driver
   - one driver got converted to videobuf2 (s2255drv)
   - the e4000 tuner driver now follows an improved binding model
   - some fixes at V4L2 compat32 code
   - several fixes and enhancements at videobuf2 code
   - some cleanups at V4L2 API documentation
   - usual driver enhancements, new board additions and misc fixups"

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
  indentation in of_graph_get_next_endpoint").

  The of_graph_get_next_endpoint() function was moved and renamed by
  commit fd9fdb78a9 ("[media] of: move graph helpers from
  drivers/media/v4l2-core to drivers/of").  It was originally called
  v4l2_of_get_next_endpoint() and lived in the file
  drivers/media/v4l2-core/v4l2-of.c.

  In that original location, it was then fixed to support empty port
  nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
  nodes"), and that commit clashes badly with the dropped "Reduce
  intendation" commit.  I had to choose one or the other, and decided
  that the "Support empty port nodes" commit was more important ]

Mauro Carvalho Chehab ed97a6fe53 [media] af9033: Don't export functions for the hardware filter
Exporting functions for hardware filter is a bad idea, as it
breaks compilation if:
	CONFIG_DVB_USB_AF9035=y
	CONFIG_DVB_AF9033=m

Because the PID filter function calls would be hardcoded at
af9035.

The same doesn't happen with af9033_attach() because the
dvb_attach() doesn't hardcode it. Instead, it dynamically
links it at runtime.

However, calling dvb_attach() multiple times is problematic,
as it increments module kref.

So, the better is to pass one parameter for the af9033 module
to fill the hardware filters, and then use it inside af9035.

Oleksij Rempel b1e43f2326 [media] uvcvideo: Do not use usb_set_interface on bulk EP
The UVC specification uses alternate setting selection to notify devices
of stream start/stop. This breaks when using bulk-based devices, as the
video streaming interface has a single alternate setting in that case,
making video stream start and video stream stop events to appear
identical to the device. Bulk-based devices are thus not well supported
by UVC.

The webcam built in the Asus Zenbook UX302LA ignores the set interface
request and will keep the video stream enabled when the driver tries to
stop it. If USB autosuspend is enabled the device will then be suspended
and will crash, requiring a cold reboot.

USB trace capture showed that Windows sends a CLEAR_FEATURE(HALT)
request to the bulk endpoint when stopping the stream instead of
selecting alternate setting 0. The camera then behaves correctly, and
thus seems to require that behaviour.

Replace selection of alternate setting 0 with clearing of the endpoint
halt feature at video stream stop for bulk-based devices. Let's refrain
from blaming Microsoft this time, as it's not clear whether this
Windows-specific but USB-compliant behaviour was specifically developed
to handle bulkd-based UVC devices, or if the camera just took advantage
of it.

Shuah Khan cd701c8975 [media] em28xx: implement em28xx_usb_driver suspend, resume, reset_resume hooks
Implement em28xx_usb_driver suspend, resume, and reset_resume hooks.
These hooks will invoke em28xx core em28xx_suspend_extension() and
em28xx_resume_extension() to suspend and resume registered extensions.

Approach:
Add power management support to em28xx usb driver. This driver works in
conjunction with extensions for each of the functions on the USB device
for video/audio/dvb/remote functionality that is present on media USB
devices it supports. During suspend and resume each of these extensions
will have to do their part in suspending the components they control.

Adding suspend and resume hooks to the existing struct em28xx_ops will
enable the extensions the ability to implement suspend and resume hooks
to be called from em28xx driver. The overall approach is as follows:

-- add suspend and resume hooks to em28xx_ops
-- add suspend and resume routines to em28xx-core to invoke suspend
   and resume hooks for all registered extensions.
-- change em28xx dvb, audio, input, and video extensions to implement
   em28xx_ops: suspend and resume hooks. These hooks do what is necessary
   to suspend and resume the devices they control.

Devin Heitmueller a06b429df4 [media] au0828: rework GPIO management for HVR-950q
Restructure the way we bring the various GPIOs out of reset.  In particular:

1.  we only need to setup the GPIOs as outputs once
2.  there's no point in writing 0x40 to register 0x00 since that's the EEPROM
    write protect and already it's configured as an input
3.  Separate out the act of enabling the power supply and bringing the tuner
    and demod out of reset.  If you don't then the chip may not be properly
    enabled (as the power supply is still ramping up when the chip comes
    out of reset).  This can result in probing failures.

Frank Schaefer 123a17d142 [media] em28xx-i2c: fix the error code for unknown errors
Commit e63b009d6e "em28xx-i2c: Fix error code for I2C error transfers"
changed the code to return -ETIMEDOUT on all unknown errors.
But the proper error code for unknown errors is -EIO.
So only report -ETIMEDOUT in case of the errors 0x02 and 0x04, which
are according to Mauro Carvalho Chehab's tests related to i2c clock
stretching and return -EIO for the rest.

Commit d845fb3ae5 "em28xx-i2c: add timeout debug information if i2c_debug enabled"
has added wrong error descriptions for -ENXIO.
The strings are also missing terminating newline characters, which breaks the
output format.

Frank Schaefer cb497c75fd [media] em28xx-camera: fix return value checks on sensor probing
Since commit e63b009d6e the returned error code in case of not connected/responding
i2c clients is ENXIO isntead of ENODEV, which causes several error messages on
sensor probing.
Fix the i2c return value checks on sensor probing to silence these warnings.
