Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

2022-06-20T09:30:33+00:00

The driver uses a timer, that may submit the URB and the URB may start the timer. No simple order of killing can break te cycle. Poison the URB before killing the timer. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

The coherency rules mean that you cannot embed a buffer inside a descriptor. kmalloc() separately. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc-core: rename ir_raw_event_reset to ir_raw_event_overflow

2022-01-28T18:32:50+00:00

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

Without this, some IR will be missing mid-stream and we might decode something which never really occurred. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: harmonize infrared durations to microseconds

2020-09-03T14:18:55+00:00

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.
