media: rc-core: rename ir_raw_event_reset to ir_raw_event_overflow

2022-01-28T18:32:50Z

The driver report a reset event when the hardware reports and overflow. There is no reason to have a generic "reset" event. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: harmonize infrared durations to microseconds

2020-09-03T14:18:55Z

rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done.

media: rc: set timeout to smallest value required by enabled protocols

2018-04-20T13:14:31Z

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. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

If the lirc device supports it, set the carrier for the protocol. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: add SPDX identifiers to the code I wrote

2017-12-11T12:38:25Z

As we're now using SPDX identifiers, on the several media drivers I wrote, add the proper SPDX, identifying the license I meant. As we're now using the short license, it doesn't make sense to keep the original license text. Also, fix MODULE_LICENSE to properly identify GPL v2.

media: rc-core: consistent use of rc_repeat()

2017-08-20T13:34:39Z

The NEC decoder and the Sanyo decoders check if dev->keypressed is true before calling rc_repeat (without holding dev->keylock). Meanwhile, the XMP and JVC decoders do no such checks. This patch makes sure all users of rc_repeat() do so consistently by removing extra checks in NEC/Sanyo and modifying the check a bit in rc_repeat() so that no input event is generated if the key isn't pressed.
