Remote control support for ASUS MyCinema P7131 in saa7134 module

[Данило Шеган]

Binary package hint: linux-source-2.6.22

The TV tuner card identified as "Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d1)" with PCI IDs 0480: 1131:7133 (rev d1) has the same GPIO IR chip as the other ASUS MyCinema TV tuner cards, so it's a simple thing of setting the appropriate remote type in saa7134-cards.c and doing the same processing in saa7134-input.c.

saa7134 recognised the card as ASUS TV-FM 7135:

The following simple patch makes the card fully auto-detected:

Fixed in my git tree.

Hi,

I have this card and it works great under FC7 except for the remote control. Since I don't have the time and know-how to recompile the entire kernel, can anyone please send me the compiled module with this patch?
Or maybe tell me if I can recompile only this module...
I'm running 2.6.22.9-91

Thanks.

Looks like this never got merged. Reassigning to kernel team.

[Leann Ogasawara (leannogasawara)]

This report is remaining open against the actively developed kernel. However, against linux-source-2.6.22 this bug does not meet the criteria for a stable release update and is being marked as Won't Fix. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates . Thanks!

[Tim Gardner (timg-tpi)]

This driver appears to have active upstream support. The 2.6.22 patch does not apply, so how about refactoring the patch and provide some evidence that it will be accepted upstream?

[Leann Ogasawara (leannogasawara)]

This bug is being closed until we receive further evidence that the patch has been submitted upstream. Please reopen this report when this has been done. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks!
