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 ]

What: /sys/class/rc/
Date: Apr 2010
KernelVersion: 2.6.35
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
The rc/ class sub-directory belongs to the Remote Controller
core and provides a sysfs interface for configuring infrared
remote controller receivers.
What: /sys/class/rc/rcN/
Date: Apr 2010
KernelVersion: 2.6.35
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
A /sys/class/rc/rcN directory is created for each remote
control receiver device where N is the number of the receiver.
What: /sys/class/rc/rcN/protocols
Date: Jun 2010
KernelVersion: 2.6.36
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
Reading this file returns a list of available protocols,
something like:
"rc5 [rc6] nec jvc [sony]"
Enabled protocols are shown in [] brackets.
Writing "+proto" will add a protocol to the list of enabled
protocols.
Writing "-proto" will remove a protocol from the list of enabled
protocols.
Writing "proto" will enable only "proto".
Writing "none" will disable all protocols.
Write fails with EINVAL if an invalid protocol combination or
unknown protocol name is used.
What: /sys/class/rc/rcN/filter
Date: Jan 2014
KernelVersion: 3.15
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
Sets the scancode filter expected value.
Use in combination with /sys/class/rc/rcN/filter_mask to set the
expected value of the bits set in the filter mask.
If the hardware supports it then scancodes which do not match
the filter will be ignored. Otherwise the write will fail with
an error.
This value may be reset to 0 if the current protocol is altered.
What: /sys/class/rc/rcN/filter_mask
Date: Jan 2014
KernelVersion: 3.15
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
Sets the scancode filter mask of bits to compare.
Use in combination with /sys/class/rc/rcN/filter to set the bits
of the scancode which should be compared against the expected
value. A value of 0 disables the filter to allow all valid
scancodes to be processed.
If the hardware supports it then scancodes which do not match
the filter will be ignored. Otherwise the write will fail with
an error.
This value may be reset to 0 if the current protocol is altered.
What: /sys/class/rc/rcN/wakeup_protocols
Date: Feb 2014
KernelVersion: 3.15
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
Reading this file returns a list of available protocols to use
for the wakeup filter, something like:
"rc5 rc6 nec jvc [sony]"
The enabled wakeup protocol is shown in [] brackets.
Writing "+proto" will add a protocol to the list of enabled
wakeup protocols.
Writing "-proto" will remove a protocol from the list of enabled
wakeup protocols.
Writing "proto" will use "proto" for wakeup events.
Writing "none" will disable wakeup.
Write fails with EINVAL if an invalid protocol combination or
unknown protocol name is used, or if wakeup is not supported by
the hardware.
What: /sys/class/rc/rcN/wakeup_filter
Date: Jan 2014
KernelVersion: 3.15
Contact: Mauro Carvalho Chehab <[email protected]>
Description:
Sets the scancode wakeup filter expected value.
Use in combination with /sys/class/rc/rcN/wakeup_filter_mask to
set the expected value of the bits set in the wakeup filter mask
to trigger a system wake event.
If the hardware supports it and wakeup_filter_mask is not 0 then
scancodes which match the filter will wake the system from e.g.
suspend to RAM or power off.
Otherwise the write will fail with an error.
This value may be reset to 0 if the wakeup protocol is altered.
