The raw_register function exists to create input devices associated with that IR protocol.

2018-04-20media: rc: mce_kbd decoder: fix race conditionSean Young
The MCE keyboard sends both key down and key up events. We have a timeout handler mce_kbd_rx_timeout() in case the keyup event is never received; however, this may race with new key down events from occurring. The race is that key down scancode arrives and key down events are generated. The timeout handler races this and generates key up events straight afterwards. Since the keyboard generates scancodes every 100ms, most likely the keys will be repeated 100ms later, and now we have new key down events and the user sees duplicate key presses.

2018-04-20media: rc: mce_kbd decoder: fix stuck keysSean Young
The MCE Remote sends a 0 scancode when keys are released. If this is not received or decoded, then keys can get "stuck"; the keyup event is not sent since the input_sync() is missing from the timeout handler.

If two keys are pressed, then both keys are encoded in the scancode. This makes the mce keyboard more responsive. Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2018-04-20media: rc: mce_kbd decoder: low timeout values cause double keydownsSean Young
The mce keyboard repeats pressed keys every 100ms. If the IR timeout is set to less than that, we send key up events before the repeat arrives, so we have key up/key down for each IR repeat. The keyboard ends any sequence with a 0 scancode, in which case all keys are cleared so there is no need to run the timeout timer: it only exists for the case that the final 0 was not received.

2018-04-20media: rc: per-protocol repeat period and minimum keyup timerSean Young
Each IR protocol has its own repeat period. We can minimise the keyup timer to be the protocol period + IR timeout. This makes keys less "sticky" and makes IR more reactive and nicer to use. This feature was previously attempted in commit d57ea877af38 ("media: rc: per-protocol repeat period"), but that did not take the IR timeout into account, and had to be reverted.

2018-04-20media: rc: set timeout to smallest value required by enabled protocolsSean Young
The longer the IR timeout, the longer the rc device waits until delivering the trailing space. So, by reducing this timeout, we reduce the delay for the last scancode to be delivered. Note that the lirc daemon disables all protocols, in which case we revert back to the default value.

2018-04-16ARM: OMAP2+: Drop unused pm-noopTony Lindgren
Looks like these functions don't do anything in the mainline kernel so we can just drop it. Note that we must now also remove ir-rx51 pdata as it relies on the dummy platform data that does not do anything. And ir-rx51 is calling a pdata callback that doesn't do anything without checking if it exists first. For configuring device specific minimal latencies, the interface to use is pm_qos_add_request(). For an example, see what was done in commit 9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitches"). I've added some comments to ir-rx51 so people using it can add pm_qos support and test it.

NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al.

2018-01-30Merge branch 'misc.poll' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc.

2018-01-23media: rc: do not remove first bit if leader pulse is presentSean Young
The rc5 protocol does not have a leading pulse or space, but we encode the first bit using a single leading pulse. For other protocols, the leading pulse or space does not represent any bit. So, don't remove the first bit if a leading pulse is present.

2018-01-23media: rc: clean up leader pulse/space for manchester encodingSean Young
The IR rc6 encoder sends the header using manchester encoding using 0 bits, which causes the following: UBSAN: Undefined behaviour in drivers/media/rc/rc-ir-raw.c:247:6 shift exponent 4294967295 is too large for 64-bit type 'long long unsigned int' So, allow the leader code to send a pulse and space and remove the unused pulse_space_start field.

2018-01-23media: lirc: lirc daemon fails to detect raw IR deviceSean Young
Since commit 9b6192589be7 ("media: lirc: implement scancode sending"), and commit de142c324106 ("media: lirc: implement reading scancode") the lirc features ioctl for raw IR devices advertises two modes for sending and receiving. The lirc daemon now fails to detect a raw IR device, both for transmit and receive. To fix this, do not advertise the scancode mode in the lirc features for raw IR devices (however do keep it for scancode devices). The mode can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

2018-01-23media: lirc: add module alias for lirc_devSean Young
Since commit a60d64b15c20 ("media: lirc: lirc interface should not be a raw decoder"), there is no lirc_dev module any more. On Ubuntu 16.10, the /etc/init.d/lirc startup script attempts to load the lirc_dev module. Since this module does not exist any more, this script fails. Add an alias so the correct module is loaded.
