I wrote the CX2388[58] integrated IR controller portion of the cx23885
IR driver changes.

They are in media_tree.git on the staging/v2.6.36 branch:

http://git.linuxtv.org/media_tree.git?a=shortlog;h=refs/heads/staging/v2.6.36

Note that Igor experienced continual interrupts with the IR on the TeVii
S470, but I didn't have a problem with the HVR-1250.  So the IR for the
TeVii S470 is disabled by default and can be re-enabled with a module
option. /sbin/modinfo cx23885

You can use the code snippets for the S470 and build IR support for your
card, provided it has a CX23885 chip, and see what happens.  If your
card has a CX23888 chip, you'll have to use some IR setup code similar
to what the Hauppauge cards used.


I still have more work to do on the cx23885 integrated IR, but it should
be good enough for now.  If you have a CX23885 chip, be prepared for
continual interrupts to make your system unusable: blacklist the cx23885
module in /etc/modprobe.conf before testing.
