This patch series tries to fix the lirc interface and extend it so it can
be used to send/recv scancodes in addition to raw IR:
- Make it possible to receive scancodes from hardware that generates
scancodes (with rc protocol information)
- Make it possible to receive decoded scancodes from raw IR, from the
in-kernel decoders (not mce mouse/keyboard). Now you can take any
remote, run ir-rec and you will get both the raw IR and the decoded
scancodes plus rc protocol information.
- Make it possible to send scancodes; in kernel-encoding of IR
- Make it possible to send scancodes for hardware that can only do that
(so that lirc_zilog can be moved out of staging, not completed yet)
- Possibly the lirc interface can be used for cec?
This requires a little refactoring.
- All rc-core devices will have a lirc device associated with them
- The rc-core <-> lirc bridge no longer is a "decoder", this never made
sense and caused confusion
This requires new API for rc-core lirc devices.
- New feature LIRC_CAN_REC_SCANCODE and LIRC_CAN_SEND_SCANCODE
- REC_MODE and SEND_MODE do not enable LIRC_MODE_SCANCODE by default since
this would confuse existing userspace code
- For each scancode we need:
- rc protocol (RC_TYPE_*)
- toggle and repeat bit for some protocols
- 32 bit scancode
A separate patch will introduce new v4l-utils tools ir-rec and ir-send for
displaying and sending IR, raw or scancode.
There are few FIXMEs in the code, I am sending this for early feedback. For
example there are no encoders for most IR protocols (just nec).
However the first four patches can be merged as-is should it be accepted.
