Revert "[media] rc: rc-ir-raw: Add scancode encoder callback"

2015-08-19T10:04:49+00:00

This reverts commit 9869da5bacc5c9b865a183bd36c04be76cdd325d.

The current code is not mature enough, the API should allow a single
protocol to be specified. Also, the current code contains heuristics
that will depend on module load order.

[media] rc-core: use an IDA rather than a bitmap

2015-07-06T11:26:15+00:00

This patch changes rc-core to use the kernel facilities that are already
available for handling unique numbers instead of rolling its own bitmap
stuff.

[media] rc: nuvoton-cir: Add support for writing wakeup samples via sysfs filter callback

2015-05-14T17:37:03+00:00

Nuvoton-cir utilizes the encoding capabilities of rc-core to convert
scancodes from user space to pulse/space format understood by the
underlying hardware.

Converted samples are then written to the wakeup fifo along with other
necessary configuration to enable wake up functionality.

[media] rc: rc-core: Add support for encode_wakeup drivers

2015-05-14T17:34:53+00:00

Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true to make the
allowed wakeup protocols the same as the set of raw IR encoders.

As well as updating the sysfs interface to know which wakeup protocols
are allowed for encode_wakeup drivers, also ensure that the IR
decoders/encoders are loaded when an encode_wakeup driver is registered.

[media] rc: rc-ir-raw: Add scancode encoder callback

2015-05-14T17:17:03+00:00

Add a callback to raw ir handlers for encoding and modulating a scancode
to a set of raw events. This could be used for transmit, or for
converting a wakeup scancode filter to a form that is more suitable for
raw hardware wake up filters.
