IR receiver using nuvoton-cir and lirc required additional configuration
steps after upgrade from kernel 3.16 to 3.17-rcX. Bisected regression to
commit da6e162d6a ("[media] rc-core:
simplify sysfs code").
The regression comes from adding function change_protocol in ir-raw.c.
It changes behaviour so that only the protocol enabled by driver's
map_name will be active after registration. This breaks user space
behaviour, lirc does not get key press signals anymore.
Enable lirc protocol by default for ir raw decoders to restore original
behaviour.

On some hardware (au0828/au8522), the hardware is broken with
regards to the initial pulse detection. So, the driver needs to
produce a fake start pulse. That limits the acceptable protocols,
as it is not possible to produce a fake pulse that would cover
all supported protocols.
So, allow the driver to explicitly set the allowed protocols.
If the driver doesn't specify, keep the old behavior.

The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.
This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

When either of the normal or wakeup filter protocols are changed,
refresh the corresponding scancode filter, i.e. try and set the same
scancode filter with the new protocol. If that fails clear the filter
instead.
If no protocol was selected the filter is just cleared, and if no
s_filter callback exists the filter is left unmodified.
Similarly clear the filter mask when the filter is set if no protocol is
currently selected.
This simplifies driver code which no longer has to explicitly worry
about modifying the filter on a protocol change. This also allows the
change_wakeup_protocol callback to be omitted entirely if there is only
a single available wakeup protocol at a time, since selecting no
protocol will automatically clear the wakeup filter, disabling wakeup.

- filter_mask: normal scancode filter mask
- wakeup_filter: wakeup scancode filter value
- wakeup_filter_mask: wakeup scancode filter mask
A new s_filter() driver callback is added which must arrange for the

the scancode filter into a raw IR data filter, which can be applied

Since v3.12, specifically 153a60bb0f ([media] rc: add feedback led
trigger for rc keypresses), an LED trigger is activated on IR keydown
whether or not a keypress is generated (i.e. even if there's no matching
keycode). However the repeat and keyup logic isn't used unless there is
a keypress, which results in non-keypress keydown events turning on the
LED and not turning it off again.
On the assumption that the intent was for the LED only to light up on
valid key presses (you probably don't want it lighting up for the wrong
remote control for example), move the led_trigger_event() call inside

This patch adds user count to rc_dev structure, the reason to add this
new member is to allow other code like lirc to open rc device directly.
In the existing code, rc device is only opened by input subsystem which
works ok if we have any input drivers to match. But in case like lirc
where there will be no input driver, rc device will be never opened.
Having this user count variable will be usefull to allow rc device to be
opened from code other than rc-main.
This patch also adds rc_open and rc_close functions for other drivers
like lirc to open and close rc devices. This functions safely increment
and decrement the user count. Other driver wanting to open rc device
should call rc_open and rc_close, rather than directly modifying the
rc_dev structure.

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.
Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.
Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.
Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).
The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).
This patch separate the different usages in preparation for
upcoming patches.
Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.
The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

For some reason, when the lirc daemon learns that a usb remote control
has been unplugged, it wants to read the sysfs attributes of the
disappearing device. This is useful for uncovering transient
inconsistencies, but less so for keeping the system running when such
inconsistencies exist.
Under some circumstances (like every time I unplug my dvb stick from
my laptop), lirc catches an rc_dev whose raw event handler has been
removed (presumably by ir_raw_event_unregister), and proceeds to
interrogate the raw protocols supported by the NULL pointer.
This patch avoids the NULL dereference, and ignores the issue of how
this state of affairs came about in the first place.

This is a custom IR protocol decoder, for the RC-6-ish protocol used by
the Microsoft Remote Keyboard, apparently developed internally at
Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and
transceiver requirements and specifications document, which also touches
on this IR keyboard/mouse device.
Its a standard keyboard with embedded thumb stick mouse pointer and
mouse buttons, along with a number of media keys. The media keys are
standard RC-6, identical to the signals from the stock MCE remotes, and
will be handled as such. The keyboard and mouse signals will be decoded
and delivered to the system by an input device registered specifically
by this driver.
Successfully tested with multiple mceusb-driven transceivers, as well as
with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware
with enough sampling resolution should be able to use this decoder,
nothing about it is at all receiver-hardware-specific.
This work is inspired by lirc_mod_mce:
The documentation there and code aided in understanding and decoding the
protocol, but the bulk of the code is actually borrowed more from the
existing in-kernel decoders than anything. I did recycle the keyboard
keycode table, a few defines, and some of the keyboard and mouse data
parsing bits from lirc_mod_mce though.
Special thanks to James Meyer for providing the hardware, and being
patient with me as I took forever to get around to writing this.

Due to commit cdda911c34, evdev only
becomes readable when the buffer contains an EV_SYN/SYN_REPORT event. If
we get a repeat or a scancode we don't have a mapping for, we never call
input_sync, and thus those events don't get reported in a timely
fashion.
For example, take an mceusb transceiver with a default rc6 keymap. Press
buttons on an rc5 remote while monitoring with ir-keytable, and you'll
see nothing. Now press a button on the rc6 remote matching the keymap.
You'll suddenly get the rc5 key scancodes, the rc6 scancode and the rc6
key spit out all at the same time.
Pressing and holding a button on a remote we do have a keymap for also
works rather unreliably right now, due to repeat events also happening
without a call to input_sync (we bail from ir_do_keydown before getting
to the point where it calls input_sync).
Easy fix though, just add two strategically placed input_sync calls
right after our input_event calls for EV_MSC, and all is well again.
Technically, we probably should have been doing this all along, its just
that it never caused any functional difference until the referenced
change went into the input layer.
