[PATCH 0/6] ir-kbd-i2c conversion to the new i2c binding model (v2)
Hi all, Here comes an update of my conversion of ir-kbd-i2c to the new i2c binding model. I've split it into 6 pieces for easier review. Firstly there is 1 preliminary patch: 01-ir-kbd-i2c-dont-abuse-client-name.patch Then 3 patches doing the actual conversion: 02-ir-kbd-i2c-convert-to-new-style.patch 03-configure-ir-receiver.patch 04-ir-kbd-i2c-dont-bind-to-unsupported-devices.patch And lastly 2 patches cleaning up saa7134-input thanks to the new possibilities offered by the conversion: 04-saa7134-input-cleanup-msi-ir.patch 05-saa7134-input-cleanup-avermedia-cardbus.patch This patch set is against the v4l-dvb repository, but I didn't pay attention to the compatibility issues. I simply build-tested it on 2.6.27 and 2.6.29. This patch set touches many different drivers and I can't test any of them. My only TV card with an IR receiver doesn't make use of ir-kbd-i2c. So I would warmly welcome testers. The more testing my changes can get, the better. And of course I welcome reviews and comments as well. I had to touch many drivers I don't know anything about so it is possible that I missed something. The main difference with my initial patch set is that the ir-kbd-i2c devices are named ir_video instead of ir-kbd. The new name was chosen neutral to make it clear that alternative drivers can bind to these devices if so is the user's desire (lirc comes to mind). Such drivers will need to be updated, but with the legacy binding model going away, that had to happen anyway. I'll post all 6 patches as replies to this post. They can also be temporarily downloaded from: http://jdelvare.pck.nerim.net/linux/ir-kbd-i2c/ Additionally I've put a combined patch there, to make testing easier: http://jdelvare.pck.nerim.net/linux/ir-kbd-i2c/ir-kbd-i2c-conversion-ALL-IN-ONE.patch But for review the individual patches are much better.

I realized that ir-kbd-i2c.c:ir_probe() would need a fix-up for address 0x71 for cx18 (and ivtv) or I would need to set the parameters via struct IR_i2c_init_data. There's a usable get_key function for Hauppauge remotes in ir-kbd-i2c, but no way via struct IR_i2c_init_data to specify that one wants to use it from the bridge driver. Nor is there a way to set the RC5 ir_type from the bridge driver. So mucking with ir-kbd-i2c.c for address 0x71 is what I did next. Yeah, ir-kbd-i2c is messy, setup for some boards is done in the ir-kbd-i2c driver itself and for some other boards it is done in the bridge driver. I presume that the idea was to avoid code duplication on one hand and bloating

If Jean's change is accepted as-is, then ir-kbd-i2c will be ok but now lirc is toast. If I implement what I am suggesting, then it becomes possible at least for both cases to still work, but with a module option. Not perfect, but it is the only way I see to allow this situation to retain some sanity. In the longer term, the lirc folks are going to have to change what they are doing. Fine, that's a problem they have to solve. It's nothing I can do anyting about. But I am not going to be the instigator that breaks lirc as used by the pvrusb2 driver.
