Mauro Carvalho Chehab 3f48258e50 V4L/DVB (13039): dib0700: not building CONFIG_DVB_TUNER_DIB0070 breaks compilation
As reported by Ingo Molnar:
 Here's another new build breakage that triggers in -tip testing:

 drivers/built-in.o:(.data+0xb1f40): undefined reference to `dib0070_ctrl_agc_filter'
 drivers/built-in.o:(.data+0xb1f80): undefined reference to `dib0070_ctrl_agc_filter'

triggers due to:

CONFIG_DVB_USB_DIB0700=y
CONFIG_DVB_TUNER_DIB0070 is not set

While working on a better approach, for now, let's just select tuner
dib0070 anytime we compile dib0700.

Mauro Carvalho Chehab d4c02ef91b V4L/DVB (13038): dvbdev: Remove an anoying/uneeded warning
As pointed by Marcin Slusarz <marcin.slusarz@gmail.com>, the warns happens
because CONFIG_DVB_MAX_ADAPTERS depends on CONFIG_DVB_CORE, and there are
valid configs where DVB_CORE is not selected.

This causes such warnings, for every V4L and common drivers that may or
may not be compiled with DVB support:

drivers/media/dvb/dvb-core/dvbdev.h:36:2: warning: #warning invalid CONFIG_DVB_MAX_ADAPTERS value

We can safely remove the warning.

Kay Sievers e454cea20b Driver-Core: extend devnode callbacks to provide permissions
This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.

This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

Akihiro Tsukada 5eca4823ea V4L/DVB (13000): add driver for 774 Friio White USB ISDB-T receiver
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.

Mauro Carvalho Chehab 3d17fb1be9 V4L/DVB (12999): Add a driver for Earthsoft PT1
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.

HIRANO Takahito 98293ef3e5 V4L/DVB (12997): Add the DTV_ISDB_TS_ID property for ISDB_S
In ISDB-S, time-devision duplex is used to multiplexing several waves
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.

Fixed up trivial conflicts:

 - arch/x86/include/asm/socket.h

   converted to <asm-generic/socket.h> in the x86 tree.  The generic
   header has the same new #define's, so that works out fine.

 - drivers/net/tun.c

   fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that
   switched over to using 'tun->socket.sk' instead of the redundantly
   available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks
   to the TUN driver") which added a new 'tun->sk' use.

Janne Grunau 01886255dd V4L/DVB (12685): dvb-core: check fe->ops.set_frontend return value
Various frontend driver have parameter checks in their set_frontend
functions and return an error if the parameters are not supported,
tda10021 and cx24116 to name two.

The tuning ioctls FE_SET_FRONTEND/FE_SET_PROPERTY only change values
in the property cache and return before set_frontend is called. If a
set_frontend call in software zigzag algorithm fails and the card was
previously locked it will report a lock and the new parameters but is
still tuned to the old transport. This is not detectable from
userspace.

This change checks the return values of fe->ops.set_frontend and
changes the state to the added FESTATE_ERROR for software zigzag.
No lock will be reported to userspace if the State is FESTATE_ERROR.

Mauro Carvalho Chehab a4c1cbc781 V4L/DVB (12600): dvb-usb-remote: return KEY_RESERVED if there's free space for new keys
The input subsystem checks if get_keycode works for a scan code. Due to that,
we need to return a valid value when there's some space at the table that
can be used by a scancode.

Mauro Carvalho Chehab b77f0a7630 V4L/DVB (12599): dvb-usb-remote: Allow dynamically replacing the IR keycodes
Implements handler for EVIOCGKEYCODE/EVIOCSKEYCODE via adding two new callbacks
to the input device.

Since on dvb-usb a scan code has 16 bits, to fulfill rc5 standard codes, the default
getkeycode/setkeycode input methods would require the driver to spend up to 64 Kb of
a sparse table. Instead, add two new callbacks to the event device.

With this, it is now possible to replace the keycode tables. There are, however, a few
implementation details at the current patch:

1) It will replace the existing device keytable, instead of creating an instance
of the data. This works. However, if two devices pointing to the same table
were connected, changing the IR table of one will also change the IR table for
the other (the solution for this one is simple: just kmalloc some memory);

2) In order to change the scan code, you need first to change the key to
KEY_RESERVED or KEY_UNKNOWN to free some space at the table (solution: allocate
some additional space for newer scan codes or allow dynamic table grow);

3) The table size cannot be extended. It would be easy to allow the table to
grow dynamically: just calling kmalloc(size+1); kfree(old). Yet, maybe we can
just create a bigger table with a fixed size, like for example a table with 128
entries. This should be enough even for a very big IR.

The current issues should be addressed on a later patch.

Mauro Carvalho Chehab 2e3658836e V4L/DVB (12598): dvb-usb: store rc5 custom and data at the same field
In order to be closer to V4L IR implementation, it is needed to replace
	u8 custom, data
to:
	u16 scan

This allows using non-rc5 mappings, like the 8 bit keycodes used on older
protocols. It will also allow future implementations of rc6 keystrokes
when needed.

Mauro Carvalho Chehab 715a223323 V4L/DVB (12595): common/ir: use a struct for keycode tables
Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:

1) It requires that the scancode to be at the range 00-7f;

2) keycodes should be masked on 7 bits in order for it to work;

3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;

4) it is different than what is done with dvb-usb approach;

5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.

This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
       u16     scancode;
       u32     keycode;
};

This is very close to what dvb does. So, a further integration with DVB
code will be easy.

While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.

The only notable effect is the redution of about 35% of the ir-common
module size:

   text    data     bss     dec     hex filename
   6721   29208       4   35933    8c5d old/ir-common.ko
   5756   18040       4   23800    5cf8 new/ir-common.ko

In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.

This patch itself shouldn't be doing any functional changes.
