While some versions of xmlto accepts "Role" attribute for emphasis tag,
with some others, it fails. Better to replace it to "role" to fix the
issue.

libv4l: enable libv4l2 usage with devices which just support read(), this
allows applications to work with mpeg capture devices like the cx18, which
only do read() and only support mpeg and some exotic raw format
(which libv4l can convert).
Thanks to Simon Farnsworth <simon.farnsworth@onelan.com> for testing this.

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.

Depending on the model there are three different firmwares to choose from.
Unfortunately if a cx23885 is loaded first, then the global firmware name
is overwritten with that firmware and if ivtv is loaded next, then it
tries to load the wrong firmware. In addition, the original approach would
also overwrite any firmware that the user specified explicitly.

The input subsystem checks if get_keycode works for a scan code. Due to that,

From: Mauro Carvalho Chehab <mchehab@redhat.com>
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.

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.

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.

DocBook XML 4.1.2 is the docbook dialect spoken at Linux kernel. By
using it, we can now consider adding V4L2 API docs at the kernel tree.
As a bonus, added support for xmlto, with seems to be better supported
nowadays.
Another additional bounus is that two new Makefile targets were added:
make man - Create V4L2 API man pages
make man_install - Install V4L2 API man pages
By allowing the addition of V4L2 manpages, it is now easier for
developer to quickly check about a V4L2 API or libv4l2 call syntax and
expected return values.
