media: rc: Remove init_ir_raw_event and DEFINE_IR_RAW_EVENT macros

2018-10-04T18:22:27Z

This can be done with c99 initializers, which makes the code cleaner and more transparent. It does require gcc 4.6, because of this bug in earlier versions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Since commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6"), this is the case.

media: rc: default to idle on at startup or after reset

2018-05-14T11:14:51Z

Any spaces events received after a reset or startup should be discarded, so ensure the rc device is in idle mode. This also makes it much easier to detect incorrect raw events, as we will do in a following commit. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: meson-ir: add timeout on idle

2018-03-21T17:54:51Z

Meson doesn't seem to be able to generate timeout events in hardware. So install a software timer to generate the timeout events required by the decoders to prevent "ghost keypresses".

media: rc: remove IR_dprintk() from rc-core

2018-02-14T19:15:46Z

Use dev_dbg() rather than custom debug function. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc-core.h: minor adjustments at rc_driver_type doc

2017-12-18T15:16:04Z

The description of this enum doesn't match what it actually represents. Adjust it. Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: cec: move cec autorepeat handling to rc-core

2017-12-14T15:35:30Z

CEC autorepeat is different than other protocols. Autorepeat is triggered by the first repeated user control pressed CEC message, rather than a fixed REP_DELAY. This change also does away with the KEY_UP event directly after the first KEY_DOWN event, which was used to stop autorepeat from starting. See commit a9a249a2c997 ("media: cec: fix remote control passthrough") for the original change. Acked-by: Hans Verkuil Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: allow lirc device to be opened more than once

2017-12-14T15:35:25Z

This makes it possible for lircd to read from a lirc chardev, and not keep it busy. Note that this changes the default for timeout reports to on. lircd already enables timeout reports when it opens a lirc device, leaving them on until the next reboot.

media: lirc: implement reading scancode

2017-12-14T15:35:20Z

This implements LIRC_MODE_SCANCODE reading from the lirc device. The scancode can be read from the input device too, but with this interface you get the rc protocol, keycode, toggle and repeat status in addition to just the scancode. int main() { int fd, mode, rc; fd = open("/dev/lirc0", O_RDWR); mode = LIRC_MODE_SCANCODE; if (ioctl(fd, LIRC_SET_REC_MODE, &mode)) { // kernel too old or lirc does not support transmit } struct lirc_scancode scancode; while (read(fd, &scancode, sizeof(scancode)) == sizeof(scancode)) { printf("protocol:%d scancode:0x%x toggle:%d repeat:%d\n", scancode.rc_proto, scancode.scancode, !!(scancode.flags & LIRC_SCANCODE_FLAG_TOGGLE), !!(scancode.flags & LIRC_SCANCODE_FLAG_REPEAT)); } close(fd); } Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: remove last remnants of lirc kapi

2017-12-14T15:35:20Z

rc-core has replaced the lirc kapi many years ago, and now with the last driver ported to rc-core, we can finally remove it. Note this has no effect on userspace. All future IR drivers should use the rc-core api. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: create rc-core open and close lirc functions

2017-12-14T15:35:19Z

Replace the generic kernel lirc api with ones which use rc-core, further reducing the lirc_dev members. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
