cx23885: Support for IR-Remote on boad TBV-6920

cx23885: Support for IR-Remote on boad TBV-6920

[Simon Waid]

Hello!

I am trying to get the remote control of my DVB 6920 (cx23885) to work. 

I found out that the wiring of the sensor is the same as on the TiVii
S470, so there is little work to be done. Unfortunately, the IR part of
cx23885 driver inside the kernel is buggy. You fixed that, right? Could
you please give me access to your current cx23885 driver? 

Best regards,
Simon Waid

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.

Andy
