Subject: [media] rc-core: ir_core_dev_number can be static

Fix sparse warning:
	drivers/media/rc/rc-main.c:27:1: sparse: symbol 'ir_core_dev_number' was not declared. Should it be static?

Subject: [media] media: rc: only turn on LED if keypress generated

Since v3.12, specifically 153a60bb0fac ([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.

Subject: [media] media: rc: add raw decoder for Sharp protocol

Add a raw decoder for the Sharp protocol. It uses a pulse distance
modulation with a pulse of 320us and a bit period of 2ms for a logical 1
and 1ms for a logical 0. The first part of the message consists of a
5-bit address, an 8-bit command, and two other bits, followed by a 40ms
gap before the echo message which is an inverted version of the main
message except for the address bits.

Subject: [media] nuvoton-cir: Don't touch PS/2 interrupts while initializing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: [media] rc: ir-raw: Load ir-sharp-decoder module at init

Commit 1d184b0bc13d ([media] media: rc: add raw decoder for Sharp
protocol) added a new raw IR decoder for the sharp protocol, but didn't
add the code to load the module at init as is done for other raw
decoders, so add that code now.

Subject: [media] media: rc: add sysfs scancode filtering interface

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).

Subject: [media] media: rc: change 32bit NEC scancode format

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.

Subject: [media] rc-main: store_filter: pass errors to userland
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: [media] nuvoton-cir: Activate PNP device when probing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On certain motherboards (mainly Intel NUC series) bios keeps the
Nuvoton CIR device disabled at boot.

This patch adds a call to kernel PNP layer to activate the device if it
is not already activated. This will improve the chances of the PNP probe
actually succeeding on Intel NUC platforms.

Subject: [media] rc-main: add generic scancode filtering
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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
callback exists. This allows raw IR decoder events to be filtered, and
potentially allows hardware decoders to set looser filters and rely on
generic code to filter out the corner cases.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

The allowed and enabled protocol masks need to be expanded to be per
filter type in order to support wakeup filter protocol selection. To
ease that process abstract access to the rc_dev::allowed_protos and
rc_dev::enabled_protocols members with inline functions.

Subject: [media] rc: add allowed/enabled wakeup protocol masks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a wakeup_protocols sysfs file which controls the new
rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of
protocols that are used for the wakeup filter.

A new RC driver callback change_wakeup_protocol() is called to change
the wakeup protocol mask.

Subject: [media] rc-main: automatically refresh filter on protocol change
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: [media] rc: img-ir: add raw driver

Add raw IR remote control input driver for the ImgTec Infrared decoder
block's raw edge interrupts. Generic software protocol decoders are used
to allow multiple protocols to be supported at a time, including those
not supported by the hardware decoder.

Subject: [media] rc: img-ir: add hardware decoder driver

Add remote control input driver for the ImgTec Infrared block hardware
decoder, which is set up with timings for a specific protocol and
supports mask/value filtering and wake events.

The hardware decoder timing values, raw data to scan code conversion
function and scan code filter to raw data filter conversion function
will be provided in separate files for each protocol which this part of
the driver can use. The new generic scan code filter interface is made
use of to reduce interrupts and control wake events.

Subject: [media] rc-main: fix missing unlock if no devno left

While playing with make coccicheck I noticed this message:
drivers/media/rc/rc-main.c:1245:3-9: preceding lock on line 1238

It was introduced by commit 587d1b06e07b ([media] rc-core: reuse device
numbers) which returns -ENOMEM after a mutex_lock without first
unlocking it when there are no more device numbers left. The added code
doesn't depend on the device lock, so move it before the lock is taken.

Subject: [media] rc: img-ir: jvc: Remove unused no-leader timings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

This fixes the following warnings with W=1:
drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: initialized field overwritten [-Woverride-init]
drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: (near initialization for ‘img_ir_jvc.timings.s00’) [-Woverride-init]

The calculated values for the minlen and maxlen fields, which were
rounded to multiples of 2 and clamped to a valid range, were left
unused. Use them in the calculation of the register value rather than
using the raw input minlen and maxlen.

This fixes the following warning with a W=1 build:

Subject: [media] rc-core: do not change 32bit NEC scancode format for now
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts 18bc17448147e93f31cc9b1a83be49f1224657b2 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).

Subject: [media] rc-core: split dev->s_filter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Overloading dev->s_filter to do two different functions (set wakeup filters
and generic hardware filters) makes it impossible to tell what the
hardware actually supports, so create a separate dev->s_wakeup_filter and
make the distinction explicit.

Subject: [media] rc-core: remove generic scancode filter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Based on a patch from James Hogan <james.hogan@imgtec.com>, but this
version also makes sure that only the valid sysfs files are created
in the first place.
