Hello, I'm trying to use an IR driver written for my SoC: https://github.com/mansr/linux-tangox/blob/master/drivers/media/rc/tangox-ir.c I added these options to my defconfig: +CONFIG_MEDIA_SUPPORT=y +CONFIG_MEDIA_RC_SUPPORT=y +CONFIG_RC_DEVICES=y +CONFIG_IR_TANGO=y (I don't think I need the RC decoders, because the HW is supposed to support HW decoding of NEC, RC5, RC6). These are the logs printed at boot: [ 1.827842] IR NEC protocol handler initialized [ 1.832407] IR RC5(x/sz) protocol handler initialized [ 1.837491] IR RC6 protocol handler initialized [ 1.842049] IR JVC protocol handler initialized [ 1.846606] IR Sony protocol handler initialized [ 1.851248] IR SANYO protocol handler initialized [ 1.855979] IR Sharp protocol handler initialized [ 1.860708] IR MCE Keyboard/mouse protocol handler initialized [ 1.866575] IR XMP protocol handler initialized [ 1.871232] tango-ir 10518.ir: SMP86xx IR decoder at 0x10518/0x105e0 IRQ 21 [ 1.878241] Registered IR keymap rc-empty [ 1.882457] input: tango-ir as /devices/platform/soc/10518.ir/rc/rc0/input0 [ 1.889473] tango_ir_open [ 1.892105] rc rc0: tango-ir as /devices/platform/soc/10518.ir/rc/rc0 I was naively expecting some kind of dev/input/event0 node I could cat to grab all the remote control key presses.

(It works in a legacy system, using a different driver.) I suppose I am missing some important piece of the puzzle? I hope someone can point me in the right direction. Regards.
