The minimum possible timeout of ite-cir is 8 samples, which is
typically about 70us. The driver however changes the FIFO trigger
level from the hardware's default of 1 byte to 17 bytes, so the minimum
usable timeout value is 17 * 8 samples, which is typically about 1.2ms.
Tests showed that using timeouts down to 1.2ms actually work fine.
The current default timeout of 200ms is much longer than necessary and
the maximum timeout of 1s seems to have been chosen a bit arbitrarily.
So change the minimum timeout to the driver's limit of 17 * 8 samples
and bring timeout and maximum timeout in line with the settings
of many other receivers.

Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.
The patch has been created with the following command without manual edits:
git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
$a=join("", <F>);
$a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m
&& $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m;
close(F);
open(F, "> $ENV{i}");
print F $a;
close(F);'; done

Thanks to the intrepid testing and debugging of Matthijs van Drunen, it
was uncovered that at least some variants of the ITE8709 need to use pnp
resource 2, rather than 0, for things to function properly. Resource 0
has a length of only 1, and if you try to bypass the pnp_port_len check
and use it anyway (with either a length of 1 or 2), the system in
question's trackpad ceased to function.
The circa lirc 0.8.7 lirc_ite8709 driver used resource 2, but the value
was (amusingly) changed to 0 by way of a patch from ITE themselves, so I
don't know if there may be variants where 0 actually *is* correct, but
at least in this case and in the original lirc_ite8709 driver author's
case, it sure looks like 2 is the right value.
This fix should probably be applied to all stable kernels with the
ite-cir driver, lest we nuke more people's trackpads.

This is a second version of an rc-core based driver for the ITE Tech IT8712F
CIR and now for a pair of other variants of the IT8512 CIR too.
This driver should replace the lirc_it87 and lirc_ite8709 currently living in
the LIRC staging directory.
The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last
one yet untested) PNP ID's.
The code doesn'te reuse code from the pre-existing LIRC drivers, but has been
written from scratch using the nuvoton.cir driver as a skeleton.
This new driver shouldn't exhibit timing problems when running under load (or
with interrupts disabled for relatively long times). It works OOTB with the
RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but
I'm unable to test it since my hardware lacks TX capability.
