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: remove name from lirc_dev

2017-12-14T15:35:20Z

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

2017-12-14T15:35:19Z

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

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

2017-12-14T15:35:18Z

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

2017-12-14T15:35:18Z

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

2017-12-14T15:35:17Z

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: lirc interface should not be a raw decoder

2017-12-14T15:35:16Z

The lirc user interface exists as a raw decoder, which does not make much sense for transmit-only devices. In addition, we want to have lirc char devices for devices which do not use raw IR, i.e. scancode only devices. Note that rc-code, lirc_dev, ir-lirc-codec are now calling functions of each other, so they've been merged into one module rc-core to avoid circular dependencies. Since ir-lirc-codec no longer exists as separate codec module, there is no need for RC_DRIVER_IR_RAW_TX type drivers to call ir_raw_event_register().

media: lirc: remove LIRCCODE and LIRC_GET_LENGTH

2017-12-14T15:35:14Z

LIRCCODE is a lirc mode where a driver produces driver-dependent codes for receive and transmit. No driver uses this any more. The LIRC_GET_LENGTH ioctl was used for this mode only. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc_dev: remove min_timeout and max_timeout

2017-10-11T16:37:36Z

There are no users of this functionality (ir-lirc-codec.c has its own implementation and lirc_zilog.c doesn't use it) so remove it. This only affects users of the lirc kapi, not rc-core drivers. Signed-off-by: David Härdeman Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

[media] media: lirc_dev: merge struct irctl into struct lirc_dev

2017-10-04T17:53:07Z

The use of two separate structs (lirc_dev aka lirc_driver and irctl) makes it much harder to follow the proper lifetime of the various structs and necessitates hacks such as keeping a copy of struct lirc_dev inside struct irctl. Merging the two structs means that lirc_dev can properly manage the lifetime of the resulting struct and simplifies the code at the same time.
