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 4329b93b283c ("of: Reduce
indentation in of_graph_get_next_endpoint").
The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9bf ("[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 b9db140c1e46 ("[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 ]

The allowed and enabled protocol masks need to be expanded to be per
filter type in order to support wakeup filter protocol selection. To
ease that process abstract access to the rc_dev::allowed_protos and
rc_dev::enabled_protocols members with inline functions.

UHID_CREATE2:
HID report descriptor data (rd_data) is an array in struct uhid_create2_req,
instead of a pointer. Enables use from languages that don't support pointers,
e.g. Python.
UHID_INPUT2:
Data array is the last field of struct uhid_input2_req. Enables userspace to
write only the required bytes to kernel (ev.type + ev.u.input2.size + the part
of the data array that matters), instead of the entire struct uhid_input2_req.
Note:
UHID_CREATE2 increases the total size of struct uhid_event slightly, thus
increasing the size of messages that are queued for userspace. However, this
won't affect the userspace processing of these events.

Multitouch touchpads built for Win 8.1 need to be sent an input mode feature report
in order to start reporting multitouch events. This is the same process sent
to Win 7 multitouch touchscreens except the value of the feature report is 3 for

touchpad to a mouse. It thus presents several generic collections which
are currently ignored by hid-multitouch. Enable them by not ignoring
them in mt_input_mapping.

The default multitouch protocol class in use since the kernel v3.9 is
working quite well. Since its inclusion, the only devices we had to tweak
were those who really need quirks (GeneralTouch, FocalTech and Wistron,
the 3 of them are Win 7 certified ones).
The flow of new unhandled devices has stopped, which is great and I think
it's time to reduce the list of registered device.
This commit removes only the registration in the kernel of devices that
use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I
checked all the recordings I have, and the produced input device and
events are the same before and after applying the patch.
This gives two benefits:
- remove a bunch of lines of codes
- prevent bad handling of existing registered devices which are using a
different protocol while using the same VID/PID (I got the case of a
Quanta 3008 recently).
I also removed the associated classes (MT_CLS*). I kept their #define in
case people use the new_id sysfs node with a non standard class (their
should be really few people now, but we never now). This is why there
are /* reserved .... */.
Last, I add a comment on top of mt_devices[] definition to remember people
(and myself) not to include devices for the beauty of it.
To people still trying to add devices with the default class:
"""
Guys, try out your device under a kernel greater or equal to v3.9. If it
works, you are all set. Adding your VID/PID to the kernel only brings us
overload and you won't get anything from it _because_ even a backport of
this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or
even 3.8.
So if it works, it works.
If it does not work, then yes, submit a patch or call for help.
In any cases, if you want me to do regression tests, I'd be happy to
get some traces of your device. But I won't patch the kernel if it works.

In HID sensor hub, HID physical ids are used to represent different sensors.
For example physical id of 0x73 in usage page = 0x20, represents an
accelerometer. The HID sensor hub driver uses this physical ids to create
platform devices using MFD. There is 1:1 correspondence between an phy id and a
client driver.
But in some cases these physical ids are reused. There is a phy id 0xe1, which
specifies a custom sensor, which can exist multiple times to represent various
custom sensors. In this case there can be multiple instances of client MFD
drivers, processing specific custom sensor. In this case when client driver
looks for report id or a field index, it should still get the report id
specific to its own type. This is also true for reports, they should be
directed towards correct instance. This change introduce a way to parse and
tie physical devices to their correct instance.
Summary of changes:
- To get physical ids, use collections. If a collection of type=physical
exist then use usage id as in the name of platform device name
- As part of the platform data, we assign a hdsev instance, which has
start and end of collection indexes. Using these indexes attributes
can be tied to correct MFD client instances
- When a report is received, call callback with correct hsdev instance.
In this way using its private data stored as part of its registry, it
can distinguish different sensors even when they have same physical and
logical ids.

In some report descriptors, they leave holes in the selectors. In
this case if we use hardcoded selector values, this will result
in invalid values. For example, if there is selectors defined for
Power State from OFF to D0 to D3. We can't use indexes of these states
if some states are not implemented or not present in the report decriptors.
In this case, we need to get the indexes from report descriptors.
One API is added to get the index of a selector. This API will
search for usage id in the field usage list and return the index.

hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)
To do so, we need to introduce two new quirks:
* HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the
transport driver to use the interrupt channel to send output report
(and thus force to use HID_REQ_SET_REPORT command)
* HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not
include the report ID in the buffer it sends to the device through
HID_REQ_SET_REPORT in case of an output report
This also fixes a regression introduced in commit 3a75b24949a8
(HID: hidraw: replace hid_output_raw_report() calls by appropriates ones).
The hidraw API was not able to communicate with the PS3 SixAxis
controllers in USB mode.

If a Sixaxis or Dualshock 4 controller is connected via USB while already
connected via Bluetooth it will cause duplicate devices to be added to the
input device list.
To prevent this a global list of controllers and their MAC addresses is
maintained and new controllers are checked against this list. If a duplicate
is found, the probe function will exit with -EEXIST.
On USB the MAC is retrieved via a feature report. On Bluetooth neither
controller reports the MAC address in a feature report so the MAC is parsed from
the uniq string. As uniq cannot be guaranteed to be a MAC address in every case
(uHID or the behavior of HIDP changing) a parsing failure will not prevent the
connection.

Only initialize force feedback for devices that actually support it (Sixaxis and
Dualshock 4) to prevent calls to schedule_work() with an uninitialized work
queue.
Move the cancel_work_sync() call out of sony_destroy_ff() since the state worker
is used for the LEDs even when force-feedback is disabled.
Remove the sony_destroy_ff() function since it is no longer used.

By default, the Dualshock 4 sends controller data via report 1. Once a valid
output report 0x11 is received or a feature report of type 0x02 is requested the
controller changes from sending data in report 1 to sending data in report 17,
which is unmapped in the default descriptor. The mappings have to be moved to
report 17 to let the HID driver properly process the incoming reports.

The Dualshock4 controller contains a RGB LED, which is enabled via
the '/sys/class/leds' interface. At present the driver only returns
whether each of the RGB LEDs is lit (ie not off), but no indication
of it's brightness.
This patch fixes the reading of the current brightnes so that it
returns the value (rather than just off=0, on=LED_FULL).
Tested on the DS4 and SixAxis (for compatibility).

hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)
hid_output_raw_report(hdev, buf, sizeof(buf), HID_FEATURE_REPORT);
is strictly equivalent to:
hid_hw_raw_request(hdev, buf[0], buf, sizeof(buf),
HID_FEATURE_REPORT, HID_REQ_SET_REPORT);
Then replace buf[0] by the appropriate define.
So use the new api.
