[media] rc: interim support for 32-bit NEC-ish scancodes
The Apple and TiVo remotes I've got use an NEC-ish protocol, but rather
than a command/not_command pair, they have what appear to be vendor ID
bytes. This change makes the NEC decoder warn if the command/not_command
checksum fails, but then passes along a full 32-bit scancode for keymap
lookup. This change should make no difference for existing keymaps,
since they simply won't have 32-bit scancodes, but allows for a 32-bit
keymap. At the moment, that'll have to be uploaded by the user, but I've
got Apple and TiVo remote keymaps forthcoming.
In the long run (2.6.40, hopefully), we should probably just always use
all 32 bits for all NEC keymaps, but this should get us by for 2.6.39.
(Note that a few of the TiVo keys actuallly *do* pass the command
checksum, so for now, the keymap for this remote will have to be a mix
of 24-bit and 32-bit scancodes, but so be it).

[media] rc/keymaps: Remove the obsolete rc-rc5-tv keymap
This keymap were used for the Hauppauge Black remote controller
only. It also contains some keycodes not found there. As the
Hauppauge Black is now part of the hauppauge keymap, just remove
it.
Also, remove the modprobe hacks to select between the Gray
and the Black versions of the remote controller as:
- Both are supported by default by the keymap;
- If the user just wants one keyboard supported,
it is just a matter of changing the keymap via
the userspace tool (ir-keytable), removing
the keys that he doesn't desire. As ir-keytable
auto-loads the keys via udev, this is better than
obscure modprobe parameters.

[media] remove the old RC_MAP_HAUPPAUGE_NEW RC map
The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

[media] rc/keymaps: Rename Hauppauge table as rc-hauppauge
There are two "hauppauge-new" keymaps, one with protocol
unknown, and the other with the protocol marked accordingly.
However, both tables are miss-named.
Also, the old rc-hauppauge-new is broken, as it mixes
three different controllers as if they were just one.
This patch solves half of the problem by renaming the
correct keycode table as just rc-hauppauge. This table
contains the codes for the four different types of
remote controllers found on Hauppauge cards, properly
mapped with their different addresses.

[media] lirc_zilog: Add ref counting of struct IR, IR_tx, and IR_rx
This is a major change to add pointer reference counting for

This ref counting gets lirc_zilog closer to gracefully handling
bridge drivers and hot-unplugged USB devices disappearing out from
under lirc_zilog when the /dev/lircN node is still open. (mutexes
to protect the i2c_client pointers in struct IR_tx and struct IR_rx
still need to be added.)
This reference counting also helps lirc_zilog clean up properly

[media] lirc_zilog: Remove broken, ineffective reference counting
The set_use_inc() and set_use_dec() functions tried to lock
the underlying bridge driver device instance in memory by
changing the use count on the device's i2c_clients. This
worked for PCI devices (ivtv, cx18, bttv). It doesn't
work for hot-pluggable usb devices (pvrusb2 and hdpvr).
With usb device instances, the driver may get locked into
memory, but the unplugged hardware is gone.
The set_use_inc() set_use_dec() functions also tried to have
lirc_zilog change its own module refernce count, which is
racy and not guaranteed to work. The lirc_dev module does
actually perform proper module ref count manipulation on the
lirc_zilog module, so there is need for lirc_zilog to
attempt a buggy module get on itself anyway.
lirc_zilog also errantly called these functions on itself
in open() and close(), but lirc_dev did that already too.
So let's just gut the bodies of the set_use_*() functions,
and remove the extra calls to them from within lirc_zilog.
Proper reference counting of the struct IR, IR_rx, and IR_tx
objects -- to handle the case when the underlying
bttv, ivtv, cx18, hdpvr, or pvrusb2 bridge driver module or
device instance goes away -- will be added in subsequent
patches.

[media] lirc: remove staging lirc_it87 and lirc_ite8709 drivers
Remove older drivers lirc_it87 and lirc_ite8709 from the LIRC staging area,
since they're now superceded by ite-cir.

[media] rc: New rc-based ite-cir driver for several ITE CIRs
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.

-1. Both ir-kbd-i2c and lirc_zilog provide support for RX events.
-The 'tx_only' lirc_zilog module parameter will allow ir-kbd-i2c
-and lirc_zilog to coexist in the kernel, if the user requires such a set-up.
-However the IR unit will not work well without coordination between the
-two modules. A shared mutex, for transceiver access locking, needs to be
-supplied by bridge drivers, in struct IR_i2_init_data, to both ir-kbd-i2c
-and lirc_zilog, before they will coexist usefully. This should be fixed
-before moving out of staging.
-
-2. References and locking need careful examination. For cx18 and ivtv PCI

-counting and locking is acceptable if not correct. For USB connected units
-like HD PVR, PVR USB2, HVR-1900, and HVR1950, the likelyhood of an Ooops on
-unplug is probably great. Proper reference counting and locking needs to be
-implemented before this module is moved out of staging.
-
-3. The binding between hdpvr and lirc_zilog is currently disabled,

-drivers were loaded in his system. More details can be seen at:

-More tests need to be done, in order to fix the reported issue.

-4. In addition to providing a shared mutex for transceiver access
-locking, bridge drivers, if able, should provide a chip reset() callback
+1. Both ir-kbd-i2c and lirc_zilog provide support for RX events for
+the chips supported by lirc_zilog. Before moving lirc_zilog out of staging:
+
+a. ir-kbd-i2c needs a module parameter added to allow the user to tell
+ ir-kbd-i2c to ignore Z8 IR units.
+
+b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c
+ does.
+
+
+2. lirc_zilog module ref-counting need examination. It has not been
+verified that cdev and lirc_dev will take the proper module references on
+lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node
+is open.
+
+(The good news is ref-counting of lirc_zilog internal structures appears to be
+complete. Testing has shown the cx18 module can be unloaded out from under
+irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
+effects. The cx18 module could then be reloaded and irw properly began
+receiving button presses again and ir_send worked without error.)
+
+
+3. Bridge drivers, if able, should provide a chip reset() callback
to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines
-to perform Z8 chip resets via GPIO manipulations. This will allow lirc_zilog
+to perform Z8 chip resets via GPIO manipulations. This would allow lirc_zilog
to bring the chip back to normal when it hangs, in the same places the
original lirc_pvr150 driver code does. This is not strictly needed, so it
is not required to move lirc_zilog out of staging.

and installed on Hauppauge products. When working on either module, developers
must consider at least the following bridge drivers which mention an IR Rx unit
at address 0x71 (indicative of a Z8):

- * The ITE8709 device seems to be the combination of IT8512 superIO chip and
- * a specific firmware running on the IT8512's embedded micro-controller.
- * In addition of the embedded micro-controller, the IT8512 chip contains a
- * CIR module and several other modules. A few modules are directly accessible
- * by the host CPU, but most of them are only accessible by the
- * micro-controller. The CIR module is only accessible by the micro-controller.
- * The battery-backed SRAM module is accessible by the host CPU and the
- * micro-controller. So one of the MC's firmware role is to act as a bridge
- * between the host CPU and the CIR module. The firmware implements a kind of
- * communication protocol using the SRAM module as a shared memory. The IT8512
- * specification is publicly available on ITE's web site, but the communication
- * protocol is not, so it was reverse-engineered.
