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.

Some vendors have their on keymap table that are used on
all (or almost all) models for that vendor.
So, instead of specifying the keymap table per USB ID,
let's use the Vendor ID's table by default.
At the end, this will mean less code to be added when newer
devices for those vendors are added.
Of course, if rc_map is specified per board, it takes
precedence.

This tries to make them more like other remotes, and/or

Notably, the (>>) button is made KEY_FASTFORWARD, which is the
correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD,
something else entirely.)
Likewise, KEY_STOP is the Sun keyboard "interrupt program" key;
the media key is KEY_STOPCD.
A restriction is that I try to avoid keycodes above 255, as the X11
client/server protocol is limited to 8-bit key codes. If not for
this, I would have used the KEY_NUMERIC_x codes for the numbers.

Now that the protocol is part of the scancode, it is pretty easy to merge
the rc5 and streamzap decoders. An additional advantage is that the decoder

seen with e.g. Sony protocols).

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

The generic scancode filtering has questionable value and makes it
impossible to determine from userspace if there is an actual
scancode hw filter present or not.
So revert the generic parts.

version also makes sure that only the valid sysfs files are created

This reverts 18bc174481 and changes
the code at img-ir-nec.c to use the order used by the other NEC decoders.
The original patch ignored the fact that NEC32 scancodes are generated not
only in the NEC raw decoder but also directly in some drivers. Whichever
approach is chosen it should be consistent across drivers and this patch
needs more discussion.
Furthermore, I'm convinced that we have to stop playing games trying to
decipher the "meaning" of NEC scancodes (what's the customer/vendor/address,
which byte is the MSB, etc).

The JVC timings included timings intended for the secondary decoder
(which matches messages with no leader), however they were in the wrong
part of the timings structure, repeating s00 and s01 rather than being
in s10 and s11.
Distinct repeat timings can't be properly supported yet for JVC anyway
since the scancode callback cannot determine which decoder matched the
message, so for now remove these timings and don't bother to enable the
secondary decoder.

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.

Only a single allowed and enabled protocol mask currently exists in
struct rc_dev, however to support a separate wakeup filter protocol two
of each are needed, ideally as an array.
Therefore make both rc_dev::allowed_protos and rc_dev::enabled_protocols
arrays, update all users to reference the first element
(RC_FILTER_NORMAL), and add a couple more helper functions for drivers
to use for setting the allowed and enabled wakeup protocols.
We also rename allowed_protos to allowed_protocols while we're at it,
which is more consistent with enabled_protocols.

Add generic scancode filtering of RC input events, and fall back to
permitting any RC_FILTER_NORMAL scancode filter to be set if no s_filter

potentially allows hardware decoders to set looser filters and rely on
generic code to filter out the corner cases.

Propagate errors returned by drivers from the s_filter callback back to
userland when updating scancode filters. This allows userland to see
when the filter couldn't be updated, usually because it's not a valid
filter for the hardware.
Previously the filter was being updated conditionally on success of
s_filter, but the write always reported success back to userland.

Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.
So for the raw NEC data:
(LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)
We now generate the scancodes:
(MSB) 0x0000AACC (LSB) (normal NEC)
(MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
(MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)
Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.
The TiVo keymap is updated accordingly.

Add and document a generic sysfs based scancode filtering interface for
making use of IR data matching hardware to filter out uninteresting
scancodes. Two filters exist, one for normal operation and one for
filtering scancodes which are permitted to wake the system from suspend.
The following files are added to /sys/class/rc/rc?/:
- filter: normal scancode filter value
- 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
specified filter to be applied at the right time. Drivers can convert
the scancode filter into a raw IR data filter, which can be applied
immediately or later (for wake up filters).

There are reports[1] that on some motherboards loading the nuvoton-cir
disables PS/2 keyboard input. This is caused by an erroneous write of
CIR_INTR_MOUSE_IRQ_BIT to ACPI control register.
According to datasheet the write enables mouse power management event
interrupts which will probably have ill effects if the motherboard has
only one PS/2 port with keyboard in it.
The cir hardware does not need mouse interrupts to function and should
not touch them. This patch removes the illegal writes and registry
definitions.

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
the keycode check.
