media: rc: move ir-lirc-codec.c contents into lirc_dev.c

2017-12-14T15:35:23+00:00

Since removing the lirc kapi, ir-lirc-codec.c only contains lirc fops so the file name is no longer correct. By moving its content into lirc_dev.c the ugly extern struct lirc_fops is not longer needed, and everything lirc related is in one file.

media: lirc: scancode rc devices should have a lirc device too

2017-12-14T15:35:22+00:00

Now that the lirc interface supports scancodes, RC scancode devices can also have a lirc device. The only receiving feature they will have enabled is LIRC_CAN_REC_SCANCODE. Note that CEC devices have no lirc device, since they can be controlled from their /dev/cecN chardev. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: implement reading scancode

2017-12-14T15:35:20+00:00

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

2017-12-14T15:35:20+00:00

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: remove name from lirc_dev

2017-12-14T15:35:20+00:00

This is a duplicate of rcdev->driver_name. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

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

2017-12-14T15:35:19+00:00

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

media: lirc: move lirc_dev->attached to rc_dev->registered

2017-12-14T15:35:18+00:00

This is done to further remove the lirc kernel api. Ensure that every fops checks for this. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: use kfifo rather than lirc_buffer for raw IR

2017-12-14T15:35:18+00:00

Since the only mode lirc devices can handle is raw IR, handle this in a plain kfifo. Remove lirc_buffer since this is no longer needed. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: merge lirc_dev_fop_ioctl and ir_lirc_ioctl

2017-12-14T15:35:17+00:00

Calculate lirc features when necessary, and add LIRC_{S,G}ET_REC_MODE cases to ir_lirc_ioctl. This makes lirc_dev_fop_ioctl() unnecessary since all cases are already handled by ir_lirc_ioctl(). Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: validate scancode for transmit

2017-12-14T15:35:17+00:00

Ensure we reject an attempt to transmit invalid scancodes. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
