| | | | | | | | | | | If the driver reports that the hardware had an overflow, report this to userspace. It would be nice to know when this happens, and not just get a long space.

* media: mtk-cir: remove superfluous ir_raw_event_reset()Sean Young2022-01-241-12/+11
| | | | | | | | | | | | | | | | | This IR receiver has two limitations: 1) Any IR pulse or space longer than 12ms will be truncated to 12ms 2) Any pulses/spaces after the first 68 are lost ir_raw_event_reset() won't help here. If the IR cannot be decoded, any decoder should reset itself, and if it does not, this is a bug in the decoder.

* media: mtk-cir: reduce message end to fix nec repeatsSean Young2022-01-241-4/+5
| | | | | | | | | | | | | | | | The ir receiver generates an interrupt with the IR data, once a space of at least ok_count is has been seen. Currently this is about 110ms; when holding down a button on a nec remote, no such space is seen until the button is released. This means nothing happens until you release the button. The sample rate is fixed at 46us, so the maximum space that can be encoded is about 12ms. So, the set ok_count above that at 23ms.

* media: lirc: simplify gap calculationSean Young2022-01-241-13/+6
| | | | | | | | | | | | When a driver reports a timeout, no more IR activity will be reported until the next pulse. A space is inserted between the timeout and the next pulse, based on ktime. The timeout reports already a duration, so this duration should not be added to the gap. Otherwise there is no change to the functionality.

There is no reason to turn them off, and I cannot find any software which does this, so we can safely remove it. This makes the ioctl LIRC_SET_REC_TIMEOUT_REPORTS a no-op.

| | | | | | | | | | | | | | | This driver is a port of the lirc_sir driver to rc-core. However, for this driver I could not find any hardware to test, so it was done without testing. This is a mistake. There are clear bugs in the code. For example the two arguments to ktime_us_delta() are reversed, which means the result is garbage. The driver has been in the kernel for four years, and noone has ever reported an issue. So, remove this driver.
