Please copy the Linux Media ML to all Remote Controller drivers. There's
where we're discussing those drivers. No need to c/c linux-input.

Yeah, both lirc_atiusb and lirc_i2c were now obsoleted by upstream
non-staging drivers. I suggest to just drop it from Arch Linux.

Not sure about lirc_wpc8769l. David/Sean/Juan can have a better view.

Btw, there are also a number of lirc staging drivers under
drivers/staging/media/lirc/. We'd love some help trying to convert them
to use the rc core, moving them out of staging.

I've just had a cursory look at lirc_wpc8769l. The device does look similar
to winbond-cir, but not exactly the same. I wouldn't mind doing the work but
I don't have the hardware.

Again I'd like to do some work here but I don't have the hardware. I ported
the ttusbir driver after getting the device on ebay for a small amount.

Thanks for the info, we'll drop those drivers.

IIRC, Juan had a hacked-up version of the winbond-cir driver working on
his hardware back in March (the hardware seems similar enough, basically
the WEC1022 adds some additional Wake-On-IR functionality...I seem to
recall).

But I think Juan is the one to talk to. I don't have the WEC1020
hardware and I don't have his experience of adding support for it...

I did indeed look at this at the time. I still have the hardware,
should have the hardware docs somewhere, and can look at where I left
that hacked code at the time...

I really would have liked to merge in the support for it into
winbond-cir, but real life took over.

As I said, I still have the hardware around. I might get some time
around this weekend to look at it and come back with at least an idea
of what is left to be done.

Best regards,

   Juan.

I tried to find the hacked code, but it's not there anymore.

I have the docs, through, and a rough idea of what would have to be
done in order to support WEC1020 in winbond-cir.

I cannot tell when I will be able to put time into this, though :-(


Best regards,

    Juan.
