WPC8769L (WEC1020) support in winbond-cir?

WPC8769L (WEC1020) support in winbond-cir?

[Tom Gundersen]

Hi David and Juan,

I'm going through the various out-of-tree LIRC drivers to see if we
can stop shipping them in Arch Linux [0]. So far it appears we can
drop all except for lirc_wpc8769l [1] (PnP id WEC1020).

I noticed the comment in windownd-cir [2]:

 *  Currently supports the Winbond WPCD376i chip (PNP id WEC1022), but
 *  could probably support others (Winbond WEC102X, NatSemi, etc)
 *  with minor modifications.

What are your thoughts on adding support for WEC1020 upstream? Is
anyone interested in doing this work (I sadly don't have the correct
device, so can't really do it myself)?

Cheers,

Tom

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.

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...

Resending, now making sure I use plain text for the email...

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.
