This series of 15 patches improves support for IR, as discussed at the
"What are the goals for the architecture of an in-kernel IR system?"
thread.
It basically adds a raw decoder layer at ir-core, allowing decoders to plug
into IR core, and preparing for the addition of a lirc_dev driver that will
allow raw IR codes to be sent to userspace.
There's no lirc patch in this series. I have also a few other patches from
David Härdeman that I'm about to test/review probably later today, but
as I prefer to first merge what I have at V4L/DVB tree, before applying
them.
There are two patches on this series that deserve a better analysis, IMO:
- V4L/DVB: ir-core: rename sysfs remote controller class from ir to rc
As discussed, "IR" is not a good name, as this infrastructure could later
be used by other types of Remote Controllers, as it has nothing that
is specific to IR inside the code, except for the name. So, I'm proposing
to replace the sysfs notes do "rc", instead of "ir". The sooner we do
such changes, the better, as userspace apps using it are still under
development. So, an API change is still possible, without causing
much hurt.
Also, as some RC devices allow RC code transmission, we probably need to add
a TX node somewhere, associated with the same RX part (as some devices
don't allow simultaneous usage of TX and RX).
So, we have a few alternatives for the RC device sysfs node:
a) /sys/class/rc/rc0
|--> rx
---> tx
b) /sys/class/rc/rcrcv0
/sys/class/rc/rctx0
c) /sys/class/rc/rc0
and have there the RX and TX nodes/attributes mixed. IMO, (b) is a bad idea,
so, I am between (a) and (c).
- V4L/DVB: input: Add support for EVIO[CS]GKEYCODEBIG
Adds two new ioctls in order to handle with big keycode tables. As already
said, we'll need another ioctl, in order to get the maximum keycode supported
by a given device. I didn't wrote the patch for the new ioctl yet.
This patch will probably have a small conflict with upstream input, but I
prefer to keep it on my tree and fix the upstream conflicts when submiting
it, as the rest of the new IR code is also on my tree, and this patch is
needed to procced with the IR code development.
