Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.
This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.
Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.
For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.

echo "reset" > /proc/acpi/ibm/hotkey should do something non-useless,
so instead of setting it to Fn+F2, Fn+F3, Fn+F5, set it to

Some analysis of the ACPI DSDTs shows that the HKEY pre-enabled mask
is always 0x80c (FN+F3,FN+F4 and FN+F12), which are the hotkeys that
the second gen of HKEY firmware supported (the first gen didn't report
any hotkeys, the second reported these tree hotkeys but had no mask
support, and the third added mask support).
So, this is probably some sort of backwards compatibility with older
versions of the IBM ThinkVantage suite. We have no use for that, and
I know of exactly ZERO users of that attribute, anyway. Start the
process of getting rid of it.

Fix some locking, avoid exiting the kthread before kthread_stop() is
called on it, and clean up the hotkey poll routines a little bit.
Also, restore bits in the firmware mask after hotkey_source_mask is
changed. Without this, we leave events disabled...

For now, whitelist just these two firmware types. It is best to have
at least one more firmware type confirmed for Radeon 9xxx and Intel
GMA-2 ThinkPads before removing the confirmation requests entirely.

Due to rounding and clipping, exposure and gain settings do not map to
unique register values. Rather than read the registers and report gain
and exposure that may be different than the values that were set, just
cache the latest values that were set and report them. Reduce exposure
range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever.
Remove vestiges of driver signal processing that is now handled by
libv4l.

test status analog (PAL-B):
- Sometimes picture is noisy, but it becomes crystal clear after
switching between channels. (happens for example at 687.25 Mhz)
- On a lower frequency (511.25 Mhz) the picture is always sharp, but
lacks colour.
- No sound problems.
- radio untested.
Digital:
- DVB-T/H stream reception works.
- Would expect to see some more channels in the higher frequency region.
Overall is the impression that sensitivity still needs improvement
both in analog and digital modes.

This patch adds driver for 774 Friio White, ISDB-T USB receiver
Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/)
The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module.
This driver ignores all the frontend_parameters except frequency,
as ISDB-T shares the same parameter configuration across the country
and thus the device can work like an intelligent one.
As this device does not include a CAM nor hardware descrambling feature,
the driver passes through scrambled TS streams.
There is Friio Black, a variant for ISDB-S, which shares the same USB
Vendor/Product ID with White, but it is not supported in this driver.
They should be identified in the initialization sequence,
but this feature is not tested.

Add a driver for Earthsoft PT1
Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S
and ISDB-T demodulators.
This card has neither MPEG decoder nor conditional access module
onboard. It transmits only compressed and possibly encrypted MPEG data
over the PCI bus, so you need an external software decoder and a
decrypter to watch TV on your computer.
This driver is originally developed by Tomoaki Ishikawa
<tomy@users.sourceforge.jp> by reverse engineering.

in the same frequency. Each wave is identified by its own transport
stream ID, or TS ID. We need to provide some way to specify this ID
from user applications to handle ISDB-S frontends.
This code has been tested with the Earthsoft PT1 driver.

Following changes done for vpif driver to support vpif capture:-
1) Current version of display driver defined vpif register
space as part for vpif display platform driver resource
This is not correct since vpif is common across capture
and display drivers. So the resource iomap function is
moved to this module
2) Since there are common registers, a spinlock is added for
mutual exclusion.

This is the vpif capture bridge driver for DM6467. This video
supports two video channels each having a tvp5147 device at
the input. This allows simultaneous capture of NTSC/PAL video
in each of this channel. Both MMAP and USERPTR io mechanism
are supported. Currently buffer allocation happens at REQBUF
ioctl request. Since USERPTR IO is supported, this is not an
issue since user applications can allocate buffers and pass
the user space address to the driver. Following are TODOs :-
1) Adding support for allocation of buffers at init
2) VBI/HBI data service
