[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.

[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.

Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.

Adding min delay prevents crashing the frontend on continuous

This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

[media] vivi: queue_setup improvements

Drop the vid_limit module option: there is really no need to limit this.
No other driver does that. If you try to allocate more buffers then vb2
will automatically reduce the number of buffers anyway.

Also add sanity checks if the size in the fmt argument is going to be
used and drop the code that checks against *nbuffers == 0: this can
never happen (the vb2 framework ensures that) and the code was wrong
anyway since *nbuffers should have been set to the minimum number of
required buffers which is 1 for this driver.

Since vivi is often used as a template driver it is good to have this
driver be as compliant as possible. This broken code was for example
copied to the s2255 driver (which is being fixed as well).

[media] vivi: fix sequence counting

The sequence counting was not reset to 0 between each streaming run,
and it was increased only every other frame. This is incorrect behavior:
the confusion is with FIELD_ALTERNATE systems where each field is transmitted
separately and only when both fields have been received is the frame
sequence number increased.

[media] v4l2-subdev: Allow 32-bit compat ioctls

Add support for 32-bit ioctls with v4l-subdev device nodes.

Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.

We keep forgetting to add new ioctls, so this is a more robust solution.

In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

Adds a missing section to describe the remote controller interface.

The DocBook is just addin the same documentation as written at
Documentation/ABI/testing/sysfs-class-rc, using the DocBook's
way, and dropping timestamps/contact info.

While that means that we'll have the same info on two parts, there
are parts of the remote controller interface that doesn't belong
at Documentation/ABI/, and it makes sense to have everything
on the same place. This also means that we'll need to manually
track to be sure that both places will be synchronized, but, as
it is not expected much changes on it, this sync can be done
manually.

It also adds an introduction that states that the IR is a normal
evdev/input interface, plus the sysfs class nodes.

[media] media: rc: change 32bit NEC scancode format

Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.

So for the raw NEC data:
  (LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)

We now generate the scancodes:
  (MSB) 0x0000AACC (LSB) (normal NEC)
  (MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
  (MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)

Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.

The TiVo keymap is updated accordingly.

[media] media: rc: add sysfs scancode filtering interface

Add and document a generic sysfs based scancode filtering interface for
making use of IR data matching hardware to filter out uninteresting
scancodes. Two filters exist, one for normal operation and one for
filtering scancodes which are permitted to wake the system from suspend.

The following files are added to /sys/class/rc/rc?/:
- filter: normal scancode filter value
- filter_mask: normal scancode filter mask
- wakeup_filter: wakeup scancode filter value
- wakeup_filter_mask: wakeup scancode filter mask

A new s_filter() driver callback is added which must arrange for the
specified filter to be applied at the right time. Drivers can convert
the scancode filter into a raw IR data filter, which can be applied
immediately or later (for wake up filters).

[media] nuvoton-cir: Don't touch PS/2 interrupts while initializing

There are reports[1] that on some motherboards loading the nuvoton-cir
disables PS/2 keyboard input. This is caused by an erroneous write of
CIR_INTR_MOUSE_IRQ_BIT to ACPI control register.

According to datasheet the write enables mouse power management event
interrupts which will probably have ill effects if the motherboard has
only one PS/2 port with keyboard in it.

The cir hardware does not need mouse interrupts to function and should
not touch them. This patch removes the illegal writes and registry
definitions.

[media] media: rc: only turn on LED if keypress generated

Since v3.12, specifically 153a60bb0fac ([media] rc: add feedback led
trigger for rc keypresses), an LED trigger is activated on IR keydown
whether or not a keypress is generated (i.e. even if there's no matching
keycode). However the repeat and keyup logic isn't used unless there is
a keypress, which results in non-keypress keydown events turning on the
LED and not turning it off again.

On the assumption that the intent was for the LED only to light up on
valid key presses (you probably don't want it lighting up for the wrong
remote control for example), move the led_trigger_event() call inside
the keycode check.
